[0010] Regulations aimed at reducing greenhouse gas emissions and air pollutants in the shipping sector are rapidly being strengthened by regulatory bodies worldwide, including the International Maritime Organization (IMO). Consequently, the shipping and shipbuilding industries are expanding the application of various eco-friendly technologies, such as fuel switching, exhaust gas purification systems, energy efficiency improvement technologies, and low-carbon operation technologies. However, since the environmental effects of these eco-friendly technologies vary depending on factors such as the timing of application, equipment specifications, vessel type and operational characteristics, weather conditions, and cargo conditions, verifying the effectiveness of these technologies based on actual operational data is essential, and the standardization of an eco-friendly ship management system based on this verification is required.

[0011] Domestically and internationally, ship management systems are bifurcated into the IMO system, which handles ocean-going vessels operating between nations, and national systems, which manage vessels operating within domestic ports. Furthermore, existing management focuses primarily on basic ship information (such as size and performance), lacking a foundation for integrated analysis of environmental effects. In particular, to verify the practical benefits of adopting eco-friendly technologies, the entire lifecycle—from design and construction to operation and decommissioning—must be managed in an integrated manner. However, information for each stage—such as operational records, maintenance history, inspection results, and certification documents—is currently stored across multiple systems in a fragmented manner. This results in poor data consistency and limited traceability, causing environmental impact analysis to remain an indirect evaluation based on documents and reports.

[0012] For example, even if emission reduction technologies are applied to vessels, the lack of a baseline comparison basis to evaluate performance before and after application under the same route, cargo, and environmental conditions makes quantitative verification difficult during the performance evaluation of policy support projects and the reporting of environmental regulation compliance. Furthermore, due to insufficient real-time information linkage with national core systems, port control systems, and remote vessel monitoring systems, it is virtually impossible to dynamically and transparently analyze and verify the emission reduction effects resulting from the application of eco-friendly technologies.

[0013] Furthermore, while the "Eco-friendly Ship Certification System" and "Eco-friendly Ship Supply Support Project" are being promoted domestically following the enactment of the Eco-friendly Ship Act, market confusion may arise because the classification and certification criteria for eco-friendly ships, as well as the methods of linking policy support, are not fully aligned with international standards and IMO regulatory guidelines. Additionally, there is a concern that the effectiveness of certification may be diminished due to the lack of a system for continuous performance verification through subsequent operational data of certified vessels. Moreover, since information regarding the application of eco-friendly technologies is managed separately from individual vessels, it is difficult to verify whether the effects persist throughout the ship's entire lifecycle, and it is challenging to closely track performance degradation based on the aging of equipment, such as low-NOx and desulfurization devices, and maintenance history.

[0014] Furthermore, as the results of environmental impact analyses are not effectively and automatically linked to national decision-making systems—such as policy agencies' support decisions, equipment certification reviews, the operation of eco-friendly ship systems, and fuel conversion investment strategies—data-driven policy implementation and industrial investment decisions are being hindered, and the momentum for the widespread adoption of technology is not being sufficiently secured. Consequently, uncertainty regarding the verification of the effectiveness of eco-friendly technology adoption persists, which may lead to a contraction in industrial investment and a decline in technological competitiveness.

[0015] Accordingly, there is an urgent need to secure standardized eco-friendly ship management system technology that can integrate and manage the entire lifecycle of a vessel from design to decommissioning into a single flow, quantitatively and multidimensionally evaluate environmental impact reduction effects based on actual operational data, and promote the expanded adoption of eco-friendly technologies by directly linking with policy support projects and industrial decision-making systems.

[0016] Patent documents related to the present invention include Registered Patent Publication No. 10-1714028 (Registration date: March 22, 2017), Registered Patent Publication No. 10-2232540 (Registration date: March 29, 2021), Registered Patent Publication No. 10-2344468 (Registration date: December 29, 2021), and Published Patent Publication No. 10-2024-0008502 (Publication date: January 19, 2024).

[0017] An embodiment of the present invention provides an eco-friendly ship full-life history-based environmental effect management system that automatically determines whether eco-friendly technology is applied to individual ships based on certification information and policy standards, generates a standardized ship ledger capable of full-life history management of the results, and enables the continuous and consistent integrated management of full-life data extending from the design, construction, operation, and decommissioning stages.

[0018] Furthermore, by integrating and processing actual data collected from external linked systems—such as port control systems and policy agency systems, as well as technology application history by vessel, energy operation information based on actual operation, and information on equipment performance fluctuations—we provide an eco-friendly vessel full-lifecycle history-based environmental effect management system that calculates the environmental impact reduction effect compared to the same vessel or a baseline vessel as quantitative performance indicators (e.g., emission reduction, energy efficiency improvement) and establishes a scientific verification foundation directly linked to various national decision-making systems, such as certification audits, performance evaluations of policy support projects, and feasibility reviews for eco-friendly technology investments.

[0019] Furthermore, by grouping calculated environmental performance indicators according to ship technology characteristics, operation patterns, and policy response levels to provide visualization and analysis services optimized for user needs, we provide an eco-friendly ship full-lifecycle history-based environmental effect management system that supports shipowners and shipping companies in establishing strategies for improving operational efficiency and optimizing maintenance, and creates a data-driven decision-making environment capable of providing policy agencies with real-time objective information necessary for verifying the effectiveness of eco-friendly ship deployment policies and designing future regulations.

[0020] Furthermore, we aim to contribute to the creation of an eco-friendly ship ecosystem capable of proactively responding to changes in international environmental regulations by eliminating uncertainty regarding the effectiveness of introducing eco-friendly vessels, accelerating the pace of technology adoption and stimulating investment across the industry through a standardized full-lifecycle management system, and strengthening domestic technological competitiveness.

[0024] Additionally, the full-cycle history management unit may include: a data linkage management unit that performs verification according to data quality standards by applying at least one of data transmission standards, verification rules, and error correction rules to full-cycle history information input from a ship operation management system, and converts the verified full-cycle history information into a format according to a pre-set linkage standard to synchronize with existing history information; and a history information maintenance management unit that performs a function to maintain the latest state by analyzing collection time information and change history to determine whether the information is up to date, and performs a correction function for detected missing information by applying a pre-set missing information detection rule to maintain the reliability of the previously stored full-cycle history information.

[0025] Additionally, the above-mentioned environmental impact assessment unit includes: an emission calculation unit that calculates greenhouse gas emissions based on at least one of fuel consumption, energy consumption, sailing distance, and applied technology history among the full-cycle history information managed by the above-mentioned full-cycle history management unit; an effectiveness comparison unit that quantifies the environmental impact reduction effect by comparing the greenhouse gas emissions calculated by the emission calculation unit with the greenhouse gas emissions of a baseline vessel or greenhouse gas emissions prior to the application of eco-friendly technology; and an effectiveness indicator unit that converts the environmental impact reduction effect quantified by the above-mentioned effectiveness comparison unit into a performance indicator by normalizing it based on at least one of vessel size, vessel type, and operating characteristics.

[0029] Furthermore, by monitoring environmental performance based on ship operational characteristics and actual operation data, and quantitatively calculating greenhouse gas emissions, the level of performance improvement compared to a baseline vessel or prior to the application of technology can be scientifically verified. This ensures the rationality of certification procedures and the fairness of policy support program evaluations, while enhancing market confidence in eco-friendly technologies and stimulating industrial growth.

[0030] Furthermore, by providing visualized environmental performance information tailored to the specific purposes and requirements of each user, various data-driven decisions—such as improving ship operational efficiency, optimizing maintenance plans, and establishing policy response strategies—can be executed quickly and accurately. This contributes to achieving harmonious management efficiency, verifying compliance with environmental regulations, and proactively addressing risk factors.

[0031] Furthermore, based on the effects of introducing eco-friendly vessels, the policy effectiveness and operational economics of eco-friendly technologies applied at the level of the entire fleet, as well as individual vessels, can be verified. This can be utilized to support national-level technical and policy decision-making and institutional improvements. Additionally, by combining this with ship ICT technologies currently under research in Korea, it can provide a foundation for expanding a standardized eco-friendly vessel management system into the global eco-friendly vessel market, thereby contributing to strengthening international competitiveness.

[0038] FIG. 1 is a schematic diagram showing the hardware configuration and overall operation process of an eco-friendly ship full-life history-based environmental effect management system according to an embodiment of the present invention.

[0039] Referring to FIG. 1, the eco-friendly ship full-cycle history-based environmental effect management system (1000) according to the present embodiment includes a full-cycle history management server (10), a ship operation management system (20), an external linkage system (30), and a user terminal (40), and can be implemented as an integrated intelligent operation platform that collects full-cycle history data of a ship, such as technical information, operation information, and energy usage information applied to the eco-friendly ship, and quantitatively calculates the environmental impact reduction effect based on this data to evaluate the performance of the eco-friendly ship.

[0040] The above-mentioned full-cycle history management server (10) is a core component of the present invention and can be implemented as a central processing unit for integrating and analyzing certification information, technology application history information, and operation information of eco-friendly ships, and for evaluating the performance of eco-friendly technology application based on the analysis results. The full-cycle history management server (10) can be configured based on a high-performance server including one or more processors and memory, and can quantitatively compare and quantify eco-friendly performance for each ship by incorporating a data linkage management function, a full-cycle history maintenance function, and an environmental impact assessment engine. In addition, the full-cycle history management server (10) can be configured to control access rights to user terminals (40) and external linkage systems (30) and to provide data only upon approved requests.

[0041] The above-mentioned ship operation management system (20) can be implemented as an operation management device for monitoring and storing operation information, fuel usage information, energy operation information, and equipment status information generated in the operating environment of an eco-friendly ship in real time. The ship operation management system (20) can continuously generate operation data by linking with an engine monitoring device, equipment status monitoring device, navigation information collection device, and energy management system installed in the ship, and the collected information can be transmitted to a full-cycle history management server (10) to be used for analyzing the effects of applying eco-friendly technology.

[0042] The above external linkage system (30) can be implemented as an external information providing device to provide eco-friendly ship certification information, exception approval information, and policy support project linkage information from certification bodies, policy support agencies, or classification societies. The external linkage system (30) can be linked with a national certification database and an administrative information linkage system to provide the latest certification information to the full-cycle history management server (10), and can also transmit the latest standards and evaluation criteria for eco-friendly technology. Through this, the full-cycle history management server (10) can be able to generate evaluation information that conforms to the latest certification standards.

[0043] The above user terminal (40) can be implemented as an interface layer for shipowners, shipping companies, and operators to interact with the system. The user terminal (40) may include a PC-based administrator terminal, a web-based screen, a mobile terminal, or a field control panel device, and can transmit user commands, such as viewing full-cycle history information, checking performance indicators, reviewing policy project applications, and requesting data provision, to the full-cycle history management server (10). Additionally, the user terminal (40) can visualize and provide to the user the environmental impact reduction effect and performance indicators calculated by the full-cycle history management server (10).

[0044] The eco-friendly ship full-cycle history-based environmental effect management system (1000) configured in this manner receives real-time operation information and technology application history from the ship operation management system (20), and can secure eco-friendly certification information and policy support linkage information through an external linkage system (30). The full-cycle history management server (10) can standardize and store the input and linked data, and quantitatively evaluate the eco-friendly performance of each ship by performing comparative analysis based on unit emission standards and operation characteristics. The generated evaluation information can be utilized through a user terminal (40) for reviewing participation in policy support projects, establishing ship operation strategies, and determining the additional application of eco-friendly technologies.

[0045] In addition, the full-cycle history management server (10) can control requests for full-cycle history information input from a user terminal (40) and an external linkage system (30) according to authentication and approval procedures, and can strengthen data security and distribution management systems by managing the items and formats provided only for approved requests.

[0046] The eco-friendly ship full-cycle history-based environmental effect management system (1000) according to the present embodiment can continuously identify the eco-friendly performance of each ship by performing a data transmission and reception procedure between a ship operation management system (20), an external linkage system (30), and a user terminal (40) centered on a full-cycle history management server (10).

[0047] First, the ship operation management system (20) can continuously transmit key operation information, such as fuel consumption, energy consumption, sailing distance, and operation history of eco-friendly technology equipment generated during the operation of the eco-friendly ship, to the full-cycle history management server (10), and the full-cycle history management server (10) can build cumulative history information in full-cycle units based on the collected information.

[0048] Subsequently, the full-cycle history management server (10) can transmit data verification, error correction, and missing value correction commands to the ship operation management system (20) to maintain the timeliness and reliability of the collected full-cycle history information, and the results of the command execution can be reflected back into the full-cycle history management server (10). In addition, the full-cycle history management server (10) can request the provision of policy standard information from an external linkage system (30) to secure emission standards and policy linkage information for accurately calculating the environmental impact reduction effect, and the external linkage system (30) can transmit the latest certification standards and emission standard values ​​in conjunction with a certification body or a policy support agency.

[0049] Afterwards, the user terminal (40) can input authentication information and a data lookup request for the full-cycle history management server (10), and the full-cycle history management server (10) can provide the results of the analysis of environmental impact reduction effects within the permitted request range to the user terminal (40) after verifying the user's authority.

[0050] As such, the eco-friendly ship full-life history-based environmental effect management system (1000) according to the present embodiment enables comprehensive eco-friendly performance evaluation based on ship full-life data, and can integrally perform data quality maintenance, secure information linkage security, and policy support utilization, thereby contributing to the diffusion of eco-friendly ships and the optimization of their operation.

[0051] Meanwhile, the eco-friendly ship full-life history-based environmental effect management system (1000) according to the present embodiment may also be implemented as a software-based computing device in which one or more processors operate by executing program instructions stored in memory. Software for performing core functions of the system, such as an authentication information processing module, a full-life history collection and storage module, a data linkage management module, a history maintenance management module, an environmental impact calculation module, an effectiveness comparison and indicator module, an information display module, and an information linkage control module, may be stored in the memory. These modules may operate by exchanging data with each other through a common data buffer, an asynchronous message queue, or an event-based processing engine.

[0052] The above processor can execute an authentication information processing module to convert eco-friendly ship certification application information input from a user terminal (40) or an external linkage system (30) into an analyzable internal data format, and generate authentication information by performing a verification procedure for conformity to authentication standards. The generated authentication information can be transmitted to a full-cycle history collection and storage module and registered as a target for ship ledger creation and full-cycle history management.

[0053] Additionally, the processor can execute a full-cycle history collection and storage module to collect operational information, fuel usage information, energy management information, etc., that are input periodically or in real-time from the ship operation management system (20), and store them in a structured form. The stored data can be transmitted to a data linkage management module to perform consistency verification and format conversion processes according to the linkage specifications and data quality standards of the ship operation management system (20).

[0054] In addition, the processor can execute a history maintenance module to perform procedures for verifying the timeliness of stored full-cycle history information, managing change history, and correcting missing information, and can improve data quality based on reliability. The quality-maintained full-cycle history information is provided to an environmental impact calculation module and can be utilized to calculate greenhouse gas emissions per vessel.

[0055] In addition, the processor can quantify the environmental impact reduction effect by executing the environmental impact calculation module and the effectiveness comparison and quantification module to compare the calculated emissions with those of a baseline vessel or emissions prior to the application of technology, and can convert these results into performance indicators based on vessel size, type, and operational characteristics. The converted performance indicators can be utilized to support the evaluation of policy support projects and to formulate vessel operation strategies.

[0056] Additionally, the processor can execute an information display module to provide full-cycle history information and environmental impact reduction effects to the user terminal (40) in a visualized form, and can dynamically adjust the scope of data provision according to the display request conditions. Furthermore, through an information linkage control module, it can perform approval verification of data provision requests received from an external organization or the user terminal (40), set provision items, and control access rights.

[0057] As configured in this way, the eco-friendly ship full-life history-based environmental effect management system (1000) can perform all functions of certification information processing, full-life history collection and verification, environmental impact assessment, information provision, and access control based on software modules, and the processor can execute each module in a parallel or asynchronous manner to simultaneously perform real-time data quality management and analysis.

[0058] FIG. 2 is a block diagram showing the overall configuration of an environmental effect management system based on the full lifecycle history of an eco-friendly ship according to an embodiment of the present invention, FIG. 3 is a block diagram showing the detailed configuration of an eco-friendly ship determination unit according to an embodiment of the present invention, FIG. 4 is a block diagram showing the detailed configuration of a full lifecycle history management unit according to an embodiment of the present invention, FIG. 5 is a block diagram showing the detailed configuration of an environmental impact assessment unit according to an embodiment of the present invention, and FIG. 6 is a block diagram showing the detailed configuration of an information display unit according to an embodiment of the present invention.

[0059] Referring to FIG. 2, the eco-friendly ship full-cycle history-based environmental effect management system (1000) according to the present embodiment may include at least one of an eco-friendly ship determination unit (100), a full-cycle history management unit (200), an environmental impact assessment unit (300), an information display unit (400), and an information linkage control unit (500).

[0060] The above-mentioned eco-friendly ship determination unit (100) determines whether each ship is an eco-friendly ship based on the certification information of the eco-friendly ship, and can generate a ship ledger for full-cycle history management of the eco-friendly ship according to the determination result.

[0061] To this end, the eco-friendly ship determination unit (100) may include at least one of the certification information processing unit (110), the eco-friendly determination unit (120), and the ledger generation unit (130), as shown in FIG. 3.

[0062] The above certification information processing unit (110) can receive certification application information for an eco-friendly ship, convert it into a verifiable data format, and generate certification information by checking the validity of each item.

[0063] More specifically, the certification information processing unit (110) electronically collects certification application information entered for the registration of eco-friendly ships and normalizes the format and structure of the input data into a standardized data format that can be processed by the full-cycle history management server (10). In this process, essential items such as ship identification information, construction information, shipowner information, ship specifications, eco-friendly technology application information, and fuel characteristics are classified to determine whether there are abnormal or missing values, and a request for correction can be made to the inputter or the linked system for the detected error values.

[0064] In addition, the certification information processing unit (110) can verify the essential items required to be recognized as an eco-friendly ship in accordance with the Korea Eco-friendly Ship Act and the International Maritime Organization (IMO) standards, and can ensure the timeliness and accuracy of the information by comparing the declaration information submitted at the certification application stage with the databases of policy agencies or classification societies. Through this, key information such as the certification grade, certification number, and certification validity period can be legally registered.

[0065] In addition, the certification information processing unit (110) can support a structure that enables policy performance analysis by storing information on the relevant support items and support period in conjunction with the certification information when the vessel participates in a government supply support project or policy support program.

[0066] In addition, the certification information processing unit (110) can automatically verify the consistency of the technology application by comparing the eco-friendly technology application plan submitted during the design phase with the history of the actual installed equipment during the drying phase. Through this, if a discrepancy occurs between the certification application information and the actual installation information, it can automatically identify it and support subsequent verification.

[0067] In addition, the authentication information processing unit (110) can separately manage items to verify whether there is a linkage with the policy support project. For example, information such as whether there is participation in the dissemination support project, the type of supported technology, and the application period can be stored separately to provide basic data for policy performance analysis.

[0068] In addition, the authentication information processing unit (110) can maintain a personal information and sensitive information protection system by structuring and storing the generated authentication information and controlling access rights according to each user terminal (40). Through this, the authentication information can be managed integrally by linking with the full lifecycle history of the shipbuilding, operation, and decommissioning stages in the future.

[0069] In addition, the authentication information processing unit (110) can maintain the up-to-date nature of the authentication information by linking with an external linkage system (30) and updating the information in real time when additional events occur, such as updating, changing, or canceling the authentication grade.

[0070] In this way, the certification information processing unit (110) provides highly reliable basic data for the conformity determination procedure of the eco-friendly ship judgment unit (120), and can improve the efficiency and accuracy of the entire lifecycle management by converting the paper document-centered verification system into an electronic, data-based verification system.

[0071] The above-mentioned eco-friendly determination unit (120) can determine whether the certification information generated by the certification information processing unit (120) is suitable for at least one of the certification criteria and the exception approval criteria to determine whether it is an eco-friendly ship.

[0072] More specifically, the eco-friendly determination unit (120) can systematically verify whether the vessel meets the essential requirements for being recognized as an eco-friendly vessel based on the certification information transmitted from the certification information processing unit (110). To this end, the eco-friendly determination unit (120) can quantitatively determine the suitability of the input data by reflecting the emission regulation standards presented by the International Maritime Organization (IMO), the standards of eco-friendly ship laws by country, and the exception approval regulations set by policy agencies. For example, it can determine whether the vessel's environmental performance meets regulatory standards by reviewing information such as the type of applied eco-friendly technology, fuel usage method, performance of emission reduction devices, and possession of a certificate.

[0073] In addition, the eco-friendly determination unit (120) can verify whether the vessel satisfies the same environmental standards even when the vessel is modified from an existing vessel. In this process, the eco-friendliness of the modified vessel can be accurately verified by comparing the scope of technology application before and after modification, changes in equipment, and the performance certification history of the installed equipment. Through this verification procedure, not only newly built vessels but also modified vessels can be determined as eco-friendly vessels according to objective standards.

[0074] Additionally, the eco-friendly judgment unit (120) can determine the conditions for an exception approval. An exception approval refers to a procedure that allows for the temporary operation of an eco-friendly vessel even if it does not meet some eco-friendly standards, for the purpose of specific policy objectives or technology verification. The eco-friendly judgment unit (120) can determine whether the approval was legally granted by verifying relevant supporting documents. Through this, technology demonstration projects, test vessels applying new fuels, etc., can also be operated consistently within the management system.

[0075] Additionally, the eco-friendly judgment unit (120) can perform a subsequent verification procedure to monitor the consistency between the certification information and the actual field installation and operation information. For example, if equipment changes, performance degradation, or certification cancellation occur after certification, the eco-friendly judgment unit (120) can adjust the judgment grade of the vessel or determine whether renewal is necessary. This enables continuous management of the certification results.

[0076] Additionally, the eco-friendly judgment unit (120) transmits the judgment status of the vessel to the vessel ledger generation unit (130) based on the certification examination results, and can register the vessel as a full-cycle history management target upon judgment approval. Conversely, if the judgment criteria are not met, the reason for disapproval can be clearly presented to induce a re-verification procedure or the application of additional technology.

[0077] In addition, if a reason such as equipment replacement, performance degradation, or certification cancellation occurs after certification, the eco-friendly judgment unit (120) can review the existing judgment and determine whether to adjust the eco-friendly certification grade or renew it when the relevant history is transmitted through the certification information processing unit (110). Through this, the continuity and reliability of the certification can be ensured.

[0078] In this way, the eco-friendly judgment unit (120) can provide reliable standard information to be used in policy support evaluation, certification management, and full-cycle effectiveness verification stages by performing a systematic and objective suitability judgment function for eco-friendly ships.

[0079] The above ledger generation unit (130) generates a basic ledger structure including at least one of identification information, specification information, and applied eco-friendly technology information of a ship, depending on whether the ship is eco-friendly determined by the eco-friendly determination unit (120), and can register the generated basic ledger structure as a full-cycle history management target.

[0080] More specifically, the ledger generation unit (130) receives the result determined by the eco-friendly determination unit (120) and, if the vessel is certified as an eco-friendly vessel, can immediately generate a basic ledger structure to include the vessel as a subject of management for full-cycle history management. The basic ledger structure can manage the certification items that serve as the basis for determining the vessel as an eco-friendly vessel, along with the vessel's basic metadata such as vessel identification information, registered port, international identification number (IMO number), year of construction, vessel type, and gross tonnage. The ledger generation unit (130) can store this as a structured data model and allocate data storage space so that operational information, technical change history, and policy support linkage information can be accumulated thereafter.

[0081] Additionally, the ledger generation unit (130) may include basic specification information of the vessel to reflect the actual operating environment and the scope of technology application. For example, it may be configured to include specifications of the main engine and auxiliary engine, the type of propulsion system, applicable maximum output, the type and characteristics of the fuel used, and information related to emission factors, so that accurate comparison and standard calculation can be made during future environmental impact assessments. This specification information can be managed so that changes can be managed by the shipowner or shipping company, and the latest information can be updated through an external linkage system.

[0082] In addition, the ledger generation unit (130) can register information on the application of eco-friendly technologies by including it as a core attribute. For example, it can store items such as whether an alternative fuel propulsion system (LNG, ammonia, hydrogen, eFuel) is applied, whether a waste exhaust gas purification technology (SCR, EGCS) is applied, whether an energy efficiency improvement technology (EMS) is applied, and whether a heat recovery device is applied, and can manage details such as the specifications, installation location, manufacturer, and date of initial application of each technology. This information can be directly used as a basis for performance verification of each technology.

[0083] Additionally, the ledger generation unit (130) can store the modification history and the resulting changes in performance levels separately when the vessel has secured eco-friendliness through modification or performance improvement. At this time, metadata can be recorded separately at each point of history management so that the differences before and after modification can be clearly reflected, and if necessary, it can be linked with the eco-friendliness judgment unit (120) to evaluate the suitability of the modification items. Through this, not only information from the initial design stage but also changes during the actual technology application stage can be managed from a full-cycle perspective.

[0084] Additionally, the ledger generation unit (130) can be configured to register the generated basic ledger as a management target of the full-cycle history management server (10) so that it can be automatically linked with data input from the operation information collection unit (220) and the technology application history collection unit (210). At this time, the ledger generation unit (130) can set data access rights, open scope, and provision policies differently according to user types such as shipowners, policy agencies, and research institutions.

[0085] In addition, the ledger generation unit (130) may store information on policy support projects in which the vessel participated, supported technologies, support application periods, and performance indicators, and this information may be used as a basis for future environmental impact assessments and policy support performance analysis.

[0086] In addition, the ledger generation unit (130) can structure and record detailed specifications for eco-friendly technology components such as electric propulsion devices, energy storage devices, and auxiliary equipment, in addition to the main engine and propulsion device.

[0087] In this way, the ledger generation unit (130) can generate a full-cycle management ledger that serves as the starting point for management based on the core information of the vessel whose eco-friendly status has been finally confirmed, and can provide an infrastructure capable of integratedly managing various information generated during the design, construction, operation, and decommissioning stages of the vessel.

[0088] The above-mentioned full-cycle history management unit (200) collects full-cycle history information according to the lifecycle stage of an eco-friendly ship based on the ship ledger generated by the eco-friendly ship determination unit (100), and can manage the full-cycle history information through data linkage with the ship operation management system (20).

[0089] To this end, the full-cycle history management unit (200) may include at least one of a technology application history collection unit (210), an operation information collection unit (220), a full-cycle information integration unit (230), a data linkage management unit (240), and a history information maintenance management unit (250), as illustrated in FIG. 4.

[0090] The above technology application history collection unit (210) receives and collects eco-friendly technology application information registered in the ledger generation unit (130), and can structure and store the collected eco-friendly technology application information.

[0091] More specifically, the technology application history collection unit (210) can receive and collect the application time, application method, and technology specifications of each technology in chronological order, based on the eco-friendly technology application information recorded in the ship ledger generated by the ledger generation unit (130). In this process, it can identify whether the eco-friendly technology applied to the ship is a single technology or a combination of multiple technologies, and can store the identification information for each technology separately in the form of metadata to enable tracking of the effects of the technology application. The technology application history collection unit (210) can ensure the completeness of the technology application by continuously updating not only the initial installation time but also the history of technology changes such as maintenance, improvement, and upgrade.

[0092] In addition, the technology application history collection unit (210) can classify and store applied eco-friendly technologies by type. For example, it can be classified into fuel conversion technologies such as LNG, ammonia, and hydrogen propulsion systems, emission reduction technologies such as SCR and EGCS, energy efficiency improvement equipment such as EMS and waste heat recovery devices, and can store the performance specifications of each technology, such as rated output, throughput, emission reduction efficiency, installation location, manufacturer, and certification standards, as standardized attribute values. Through this, comparative analysis of technologies and review of policy effects can be easily performed.

[0093] In addition, the technology application history collection unit (210) can distinguish and store whether the technology was initially installed during new construction or was a technology resulting from modification or additional installation on an existing vessel, depending on the form of technology application. At this time, the modification or additional installation history can be clearly managed based on the time point of the data so that it can be used as a basis for environmental impact assessment considering the difference in performance before and after modification. Accordingly, even for the same vessel, if the level of the applied technology and the emission reduction capability improve over time, such changes can be quantitatively recorded.

[0094] In addition, the technology application history collection unit (210) can check whether the certification information of the installed equipment has changed by linking with an external linkage system (30), and can immediately reflect the relevant history information if negative factors such as certification cancellation or technical defects occur. Through this, the continuous up-to-dateness and reliability of the technology application information can be maintained, and error-free data can be provided during subsequent environmental impact assessment and policy support review processes.

[0095] Additionally, the technology application history collection unit (210) can store the collected technology information in a structured data format that can be processed by the full-cycle information integration unit (230) of the full-cycle history management unit (200). In this storage process, data continuity can be maintained by systematically mapping the relationship between the unique identification information for each vessel and the technology application data, thereby enabling correlation analysis between the technology application history and operational performance.

[0096] In addition, the technology application history collection unit (210) can clearly manage the history of technology application by distinguishing whether the eco-friendly technology was applied during new construction or modified or additionally installed on an existing vessel.

[0097] In addition, the technology application history collection unit (210) can separately store the equipment performance degradation rate due to long-term operation, maintenance history, and upgrade history to track how the technology performance changes over time.

[0098] In addition, the technology application history collection unit (210) can store whether the applied technology is a government-supported technology in conjunction with policy support items such as distribution support projects, and can be used as standard data for policy performance analysis.

[0099] In this way, the technology application history collection unit (210) can accurately and systematically collect and manage the entire history of eco-friendly technology applied to the ship, from installation to modification and renewal, thereby providing key basic data for future verification of the effectiveness of each eco-friendly technology and judgment of the validity of policy support.

[0100] The above-mentioned operation information collection unit (220) can collect and record operation information, including fuel consumption, energy consumption, and sailing distance, generated during the operation of an eco-friendly vessel, in chronological order.

[0101] More specifically, the operation information collection unit (220) can automatically collect operation-related information, such as fuel consumption, energy consumption, sailing distance, sailing speed, loading status, and weather conditions, which are continuously generated during the actual operation of the eco-friendly vessel, in chronological order. Through this, a detailed history of how the vessel operated at a specific point in time or on a specific route can be secured, and the collected data can be used as a key input value for an environmental impact assessment based on operation characteristics. The operation information collection unit (220) can collect information in real-time or periodic reporting manner by linking with the vessel operation management system (20), and can perform an omission verification procedure in parallel to prevent data loss.

[0102] In addition, the operational information collection unit (220) can classify and store fuel consumption information not merely at a simple aggregation level, but by detailed items to enable analysis of consumption by main engine and auxiliary engine, consumption ratio by fuel type, and fuel efficiency by operating conditions. For example, it is possible to track differences in fuel efficiency due to changes in speed on the same route and changes in energy consumption due to increased load weight, thereby enabling precise derivation of the effects of applying eco-friendly technology.

[0103] In addition, the operation information collection unit (220) can store data related to ship energy management, such as power operation information and heat source usage information. For example, in the case of a ship equipped with an electric propulsion system or electric auxiliary equipment, the coordination status between the power supply source and the consumption source can be identified, and energy usage patterns by operation mode can be analyzed, which can be utilized for future energy efficiency optimization.

[0104] In addition, the operation information collection unit (220) manages navigation record information and operation schedule information including anchoring time, so that it can comprehensively record energy consumption characteristics in non-operational states, such as standby mode while anchored. Through this, it is possible to quantitatively compare how emissions change depending on changes in operation patterns, even for the same vessel.

[0105] In addition, the operational information collection unit (220) receives both weather information and sea condition information, thereby creating a data environment that allows for the analysis of the impact of external factors, such as wave height, wind speed, and current conditions, on changes in fuel and energy consumption. Accordingly, a precise comparative evaluation reflecting actual operating conditions can be performed during the environmental impact assessment process.

[0106] Additionally, the operation information collection unit (220) can convert the collected operation information into a dedicated data structure that can be processed by the full-cycle information integration unit (230) within the full-cycle history management unit (200) and store it. At this time, the stored information is automatically mapped based on the ship identification information to enable the implementation of a long-term performance monitoring system for each ship.

[0107] In addition, the operation information collection unit (220) can store energy usage, such as propulsion energy, auxiliary power, and thermal energy, by dividing them into detailed components in conjunction with the ship energy management system.

[0108] In addition, the operation information collection unit (220) can be configured to enable overall energy efficiency analysis by accumulating and managing the use of reserve power during not only operation but also during docking.

[0109] In addition, the operation information collection unit (220) can track and manage changes in fuel consumption based on external environmental factors such as wind speed, wave height, and tides by linking with a weather information system.

[0110] In this way, the operational information collection unit (220) can provide a data base that can verify the operational effects of eco-friendly technology based on facts by securing data based on the actual operation of the ship, and can play a key role in full-cycle environmental impact assessment and policy support verification.

[0111] The above-mentioned full-cycle information integration unit (230) can store at least one of the technology application history information and operation information in an integrated manner according to the linkage standard with the ship operation management system (20), and can manage the integrated stored information as cumulative history information in full-cycle units.

[0112] More specifically, the full-cycle information integration unit (230) can integrate and store eco-friendly technology application information collected from the technology application history collection unit (210) and actual operation-based data aggregated from the operation information collection unit (220) in a format that matches the linkage specifications used by the ship operation management system (20). At this time, the data can be mapped based on the same ship identification information to enable cross-referencing between the data, and sorted by time so that the history information generated across the design, construction, operation, and decommissioning stages can be connected as a single data flow. Through this, a foundation can be established to track and analyze how performance changes or fluctuations in operating conditions after a specific technology has been applied have affected the environmental impact results.

[0113] In addition, the full-cycle information integration unit (230) can prevent information damage caused by inconsistencies in representation methods by applying a data standardization procedure during integrated storage, even if the form and source of the collected data differ. For example, since operational information may be provided as time-unit data and information provided based on specific events, the full-cycle information integration unit (230) can convert and store such data so that it aligns with a common timeline. Through this, even data transmitted from various sensors and systems can be utilized as consistent input values ​​during the analysis stage.

[0114] In addition, the full-cycle information integration unit (230) can manage the history of technical changes, policy support status, and changes in operation results over a long period based on the accumulated data stored. To this end, it can be configured to include a record of data changes, a history tracking function, and a version management function, enabling the retrieval of past information and the review of reasons for changes. These functions can significantly improve the management efficiency of eco-friendly vessels that have a history of frequent modifications and performance improvements.

[0115] In addition, the full-cycle information integration unit (230) can perform an automatic missing data verification and correction procedure when missing items are found in the technology application history or operation information in order to maintain data completeness. For example, if fuel consumption information for a specific operation section is missing, an estimated correction value can be generated by referring to surrounding time point data or equipment logs, and the correction status can be recorded separately to ensure reliability.

[0116] In addition, the full-cycle information integration unit (230) can organize the stored full-cycle history information into a hierarchical or relational data structure in preparation for information exchange with internal system analysis modules and external linked systems, and optimize it to process information inquiries by ship, period, and technology at high speed based on this. Through this, it can respond quickly to real-time or batch environmental impact analysis requests performed by the environmental impact assessment unit (300).

[0117] In addition, the full-cycle information integration unit (230) can clearly analyze the correlation between the application of technology and changes in environmental performance by aligning and storing all information generated during the design phase, construction phase, and operation phase based on the same time standard.

[0118] In addition, the full-cycle information integration unit (230) can be configured to record data change history and version information so that information from the past can be used as a basis for regression analysis or certification review.

[0119] In this way, the full-cycle information integration unit (230) can synchronize and integrate the history of technology application and actual operation information of the ship from a full-cycle perspective, and by maintaining the quality and continuity of the accumulated history information, it can provide basic data essential for supporting accurate environmental impact assessment and policy decision-making.

[0120] The above data linkage management unit (240) applies at least one of a data transmission standard, a verification rule, and an error correction rule to the full-cycle history information input from the ship operation management system (20) to perform verification according to the data quality standard, and converts the verified full-cycle history information into a format according to a pre-set linkage standard to synchronize with the existing history information.

[0121] More specifically, the data linkage management unit (240) receives full-cycle history information input through the ship operation management system (20) or an external linkage system and can first verify whether the data conforms to the transmission standard. At this time, the data linkage management unit (240) can automatically verify the suitability of the data format based on predefined linkage specifications such as transmission unit, item composition, time stamp, and data unit. This verification can detect data corruption, transmission omission, or value inconsistency that may occur during the transmission process at an early stage, thereby ensuring stable data management quality.

[0122] Additionally, the data linkage management unit (240) can apply item-specific validation rules to the received full-cycle history information. For example, it can filter out obvious abnormal values ​​or request corrections, such as when fuel consumption is negative, when the operating time is displayed as an abnormally short value, or when the equipment operating status is entered as a log with conflicting values ​​simultaneously. Through this, the reliability of the full-cycle history information can be maintained and analysis errors can be prevented.

[0123] Additionally, the data linkage management unit (240) can perform correction work on missing information or outliers according to error correction rules. In this process, missing sections can be reasonably supplemented by referring to past data patterns of the same vessel or operation logs of adjacent time periods, or items with a high probability of input error can be flagged so that they can be properly processed in a subsequent analysis stage.

[0124] Additionally, the data linkage management unit (240) can convert full-cycle history information that has passed the data quality standards into a format suitable for a pre-set internal storage standard and synchronize it with existing information stored in the full-cycle information integration unit (230). At this time, the data linkage management unit (240) can automatically perform sorting and merging according to criteria such as ship identification information, collection time, and technology application status, thereby managing the data so that duplicate storage or unnecessary overwriting does not occur.

[0125] In addition, the data linkage management unit (240) can continuously analyze the main causes affecting data quality and, if abnormal data inflow patterns are repeated, request an error warning or improvement of the data transmission format from the ship operation management system (20). Through this, the data ecosystem of the entire system can be continuously maintained and advanced.

[0126] In addition, the data linkage management unit (240) receives data only upon request from an authorized transmission system and user terminal (40) to ensure data security, and can discard or block data in the event of unauthorized access. Through this, the integrity of the full-cycle history information and access control can be maintained.

[0127] In addition, the data linkage management unit (240) can monitor the linkage status with the ship operation management system (20) in real time and, if data is missing or communication abnormalities occur, record the time and cause of the error and automatically request retransmission.

[0128] Additionally, the data linkage management unit (240) can support subsequent review by applying a reliability verification rule when values ​​collected from multiple sources differ for data at the same point in time, selecting a value with higher reliability, or marking it as conflicting data.

[0129] In addition, the data linkage management department (240) can ensure data linkage efficiency with policy organizations by supporting national and international standard data exchange formats, such as data structure conversion standards like IMO and ISO standards.

[0130] In this way, the data linkage management unit (240) performs format verification, outlier removal, specification conversion, and data synchronization functions at the input stage, thereby systematically maintaining the quality of the full-cycle history information and ensuring the reliability of the information to be used for the performance evaluation of eco-friendly ships.

[0131] The above history information maintenance management unit (250) analyzes the collection time information and change history of the full-cycle history information synchronized from the data linkage management unit (240) to determine whether it is up to date and performs a function to maintain the latest state, and can maintain the reliability of the previously stored full-cycle history information by applying a pre-set missing information detection rule and performing a correction function for the detected missing information.

[0132] More specifically, the history information maintenance unit (250) receives full-cycle history information synchronized through the data linkage management unit (240) and can determine the timeliness of the data by verifying whether the information matches the actual time of operation and the time of technology application. To this end, the history information maintenance unit (250) can determine whether an update is necessary for items that have not been updated for a specific period based on the collection timestamp assigned to each piece of information, and can apply warning criteria or an automatic update request procedure when an update delay occurs. Through this, data obsolescence due to the passage of time can be prevented.

[0133] In addition, the history information maintenance department (250) can continuously track data change history and perform a version control system so that when major events such as technology updates or equipment replacements occur, the history can be clearly distinguished from past data. For example, even if the technology is the same, if a change in manufacturer, a change in specifications, or an improvement in the application method occurs, the data before the change and the data after the change can be organized and stored in a history unit so that they are not mixed.

[0134] In addition, the history information maintenance unit (250) can automatically detect whether there is missing information among the items included in the full-cycle history information. At this time, the missing information detection rule may include detection based on an allowable range, detection based on comparison of consecutive time points, and detection based on data interrelationships. For example, if the fuel usage log is not recorded during normal operating hours, it is determined to be missing, and the missing value can be estimated by referring to the operating conditions of adjacent times.

[0135] In addition, the history information maintenance unit (250) can maintain the continuity and utility value of the data by performing a correction function rather than simple deletion when information with a high probability of missing or error is found. In this process, a correction value is set in correspondence with the past pattern or analysis standard value of the same vessel, and the correction status and correction method can be recorded as a separate history so that they can be verified later.

[0136] In addition, the history information maintenance department (250) can periodically evaluate the reliability level of the data and convert it into a quality indicator. For example, by quantifying the quality status in the form of a verification success rate, a missing data ratio, and a recency score, an environment can be provided that allows for the systematic analysis and improvement of the management level of the entire lifecycle data.

[0137] In addition, the history information maintenance department (250) can analyze the cause of repeated quality degradation of specific data items or specific equipment and, if necessary, request corrective measures from an external linkage system (30) or a user terminal (40). This can play a role in ensuring that quality management is not limited to simple inspections but is continuously improved.

[0138] In addition, the history information maintenance department (250) can automatically supplement missing data by applying a time estimation algorithm or a technical characteristic-based correction rule when missing data occurs according to the data quality management policy.

[0139] In addition, the history information maintenance department (250) can improve storage space efficiency by applying a storage policy that separates core data that must be stored for a long time from data that is deleted or summarized after the storage period.

[0140] In addition, the history information maintenance department (250) can store audit trail information for all changes in the full-cycle history information and immediately provide supporting data at the time of certification review or policy evaluation.

[0141] In addition, the history information maintenance unit (250) can maintain the integrity of the entire cycle environment information by controlling whether the original data is changed according to the access rights of the user terminal (40).

[0142] In this way, the history information maintenance department (250) can consistently ensure the reliability of eco-friendly ship performance evaluation and the accuracy of policy decision-making by performing core quality management functions to maintain the up-to-date, accurate, continuous, and complete nature of the full-cycle history information.

[0143] The above environmental impact assessment unit (300) can calculate the environmental impact reduction effect for eco-friendly ships as quantitative assessment information based on the full-cycle history information managed by the full-cycle history management unit (200).

[0144] To this end, the environmental impact assessment unit (300) may include at least one of the emission calculation unit (310), the effectiveness comparison unit (320), and the effectiveness indicator unit (330), as shown in FIG. 5.

[0145] The above emission calculation unit (310) can calculate greenhouse gas emissions based on at least one of fuel consumption, energy consumption, flight distance, and applied technology history among the full cycle history information.

[0146] More specifically, the emission calculation unit (310) receives key operational information such as fuel consumption, energy consumption, mileage, and whether eco-friendly technology is applied from the full-cycle history information, and can calculate greenhouse gas emissions generated during the actual operation process using a mathematical model or an emission factor-based calculation method. The emission calculation unit (310) can accurately reflect the difference in emissions due to changes in operating conditions, even for the same vessel, by considering the type of vessel, propulsion method, type and quality of fuel used, and specifications of equipment together.

[0147] In addition, the emission calculation unit (310) applies emission factors for each fuel type to CO₂, NO x , SO x The emissions of air pollutants, such as [mention specific fuels], can be calculated individually. For instance, when using liquefied natural gas (LNG), low-sulfur oil, biofuels, or hydrogen-based fuels, accurate emission calculations can be achieved by applying differences in carbon content and combustion efficiency for each fuel as emission factors. This enables a comparison of environmental effects resulting from different fuel application strategies.

[0148] In addition, the emission calculation unit (310) can reflect the influence of external variables such as engine load rate, operating speed, route characteristics, and weather conditions, so that the emission amount can be calculated differently depending on the operating environment even with the same fuel consumption. For example, if propulsion resistance increases due to strong wind speed or high wave height, the fuel required to maintain the same speed increases, and the emission amount may also increase, so these conditions can be reflected in the calculation process.

[0149] In addition, the emission calculation unit (310) can utilize technology application history information to reflect the performance or efficiency effect of the emission reduction device in the calculation. For example, if an SCR device is installed, the nitrogen oxide reduction efficiency, and if an EGCS device is applied, the sulfur oxide removal efficiency can be applied to the calculation to correct the actual emission amount. Through this, it is possible to calculate the emission amount that reflects actual environmental improvement effects rather than a simple theoretical value.

[0150] In addition, the emission calculation unit (310) can take into account performance degradation due to changes in applied technology or an increase in the age of the vessel, even if it is the same vessel. If the performance of the emission reduction device deteriorates due to long-term operation, the accuracy of the calculation can be maintained by reflecting the performance reduction rate compared to the time of design. This continuous performance tracking function can also be utilized for emission source management and maintenance decision-making.

[0151] In addition, the emission calculation unit (310) can enable the analysis of emission patterns in specific routes or port schedules by separating and storing the emission calculation results by time unit or route unit. Through this, high-emission routes or sections where device inefficiency occurs can be identified and used as a basis for analysis to establish future improvement strategies.

[0152] In addition, the emission calculation unit (310) can ensure the reliability of the emission calculation based on international standard calculation methods such as the Energy Efficiency Operational Indicator (EEOI), Carbon Intensity Indicator (CII), and IPCC emission factors defined by the IMO.

[0153] In addition, the emission calculation unit (310) includes a variable emission factor table that reflects emission characteristics for each propulsion system (diesel, LNG, hybrid, electric propulsion, etc.), and can accurately reflect changes in emission due to changes in fuel quality and operating conditions.

[0154] In addition, the emission calculation unit (310) can quantitatively correct the emission by applying actual emission sensor data or maintenance log information when an emission reduction facility is installed, and can automatically detect performance degradation.

[0155] In this way, the emission calculation unit (310) can provide a core function that can scientifically and quantitatively verify the application effect of eco-friendly ships by performing greenhouse gas emission calculations that comprehensively reflect actual operation-based data and technical efficiency information.

[0156] The above-mentioned effectiveness comparison unit (320) can quantify the environmental impact reduction effect by comparing the greenhouse gas emissions calculated by the emission calculation unit (310) with the greenhouse gas emissions of a baseline vessel or the greenhouse gas emissions prior to the application of eco-friendly technology, and can calculate the unit emission standard by applying at least one of the ship engine specifications, propulsion system type, and emission factor according to classification society standards, and calculate the environmental impact reduction effect relative to the unit emission standard. Here, the baseline vessel refers to a reference vessel set as a reference point for comparing environmental effects among vessels to which eco-friendly technology is not applied.

[0157] More specifically, the effectiveness comparison unit (320) can quantitatively calculate the improvement effect resulting from the application of eco-friendly technology by comparing the greenhouse gas emissions of the eco-friendly vessel calculated by the emission calculation unit (310) with the emissions of the reference vessel. The reference vessel refers to a reference vessel to which eco-friendly technology has not been applied, selected based on the same type, specifications, and operating history on the same route, and the reference data can be standardized and managed so that performance differences under the same operating conditions can be evaluated. Through this, the effectiveness comparison unit (320) can evaluate performance changes based on actual conditions in a real environment, rather than a simple theoretical comparison.

[0158] In addition, the effectiveness comparison unit (320) can apply emission factors that consider emission characteristics by ship type, propulsion method, and fuel type to calculate baseline emissions. For example, when comparing a diesel-propelled cargo ship with an electric-propelled eco-friendly ship, baseline emissions can be calculated by reflecting the carbon content of each fuel, engine thermal efficiency, and propulsion loss coefficient. Through this, changes in environmental performance due to differences in equipment efficiency can be accurately reflected even with the same amount of fuel used.

[0159] Additionally, the effectiveness comparison unit (320) includes a function to calculate the unit emission standard. The unit emission standard is a standard for ensuring comparability by correcting for differences in ship size or operating distance, and can be calculated in the form of emissions per ton-mile, emissions per kWh, or emissions corrected for cargo loading rate. When calculating the unit, the margin of error can be minimized by applying a correction factor based on the ship engine specifications, propulsion system type, ship age, classification society standards, etc.

[0160] In addition, the effectiveness comparison unit (320) can individually derive the reduction effect for each greenhouse gas emission component. For example, since the contribution to the greenhouse effect of CO₂, CH₄, N₂O, etc., differs, an emission conversion factor for each component can be applied to calculate a comprehensive environmental indicator in the unit of CO₂ equivalent tons, and it can be possible to analyze the performance impact of each technology. Based on this, it can be possible to interpret the emission reduction ranking, environmental impact cost reduction effect, etc.

[0161] In addition, the effectiveness comparison unit (320) can apply a differential method of calculating emissions depending on the characteristics of the applied eco-friendly technology. For example, if an emission reduction device SCR is applied, the nitrogen oxide reduction efficiency and, if an EGCS is applied, the sulfur oxide removal rate can be reflected based on actual values ​​or maintenance logs, and in the case of fuel conversion technology, it can be corrected by considering not only theoretical emission changes but also variables based on fuel supply quality. Through this, the calculation and comparison of emissions can be converted from a simple model-based analysis to an actual measurement-based analysis.

[0162] Additionally, the effectiveness comparison unit (320) also supports comparisons based on periods or events. Since performance deviations may occur during the stabilization period in the initial stage of technology application, analysis can be performed by excluding specific periods or by separating performance differences before and after the technology upgrade point. This makes it possible to analyze performance trends by lifecycle of eco-friendly technology.

[0163] In addition, the effectiveness comparison unit (320) may include a comparison index by route, an analysis of differences in emission patterns by sea area, and a function to apply a correction coefficient reflecting adverse weather conditions, taking into account that there are differences in emissions even within the same vessel due to changes in route, weather conditions, and loading rate. These functions can be utilized by policy agencies to manage emission-regulated sea areas and establish routes optimization strategies.

[0164] Additionally, the effectiveness comparison unit (320) can calculate the comparison results in the form of reduction amount, reduction rate, improvement index, etc., and can structure and store the analysis results so that they can be provided as visual information. For example, intuitive indicators such as a 30 percent reduction in CO₂ compared to the existing one can be generated and directly used as policy support review materials or for technology adoption decision-making.

[0165] Additionally, the effectiveness comparison unit (320) can detect performance degradation or the need for technical maintenance early through long-term trend analysis. For example, if the emission reduction device becomes old, it can estimate the reduction efficiency reduction rate and generate a maintenance warning signal if performance drops below a standard.

[0166] In addition, the effectiveness comparison unit (320) can perform an environmental effect analysis by statistically analyzing the emission deviations due to differences in operating technology and ship management levels even in the same ship type and same operating environment, thereby separating the contribution of the technology effect and the operation efficiency.

[0167] Additionally, the effectiveness comparison unit (320) can generate certification maintenance evaluation indicators by continuously comparing with a baseline established based on the period prior to the application of eco-friendly technology, and can generate a warning event if performance drops below the standard.

[0168] In this way, the effectiveness comparison unit (320) can systematically compare actual operation emission data based on full-cycle history information with a baseline vessel or a state prior to application, thereby presenting the environmental improvement results resulting from the introduction of eco-friendly technology as a highly reliable quantitative indicator and further supporting the optimization of vessel operation and policy decision-making.

[0169] The above effectiveness indicator unit (330) can convert the environmental impact reduction effect quantified by the effectiveness comparison unit (320) into a performance indicator by normalizing it based on at least one of the ship size, ship type, and operation characteristics.

[0170] More specifically, the effectiveness indicator unit (330) can convert the environmental impact reduction effect calculated by the effectiveness comparison unit (320) into a standardized performance indicator that can fairly compare the performance of each ship by normalizing it according to comparison criteria such as ship size, ship type, and operational characteristics. At this time, the effectiveness indicator unit (330) can support the evaluation of environmental performance even between ships of different sizes by receiving standard values ​​representing the ship size, such as the ship's gross tonnage, deadweight tonnage (DWT), number of passengers, and engine output, and calculating the reduction effect relative to the same size.

[0171] In addition, the effectiveness indicator unit (330) can calculate performance indicators that reflect the characteristics of each ship type. For example, since cargo ships, container ships, passenger ships, tankers, etc., have different operation patterns and efficiency characteristics, the indicator can be calculated by reflecting the representative operational characteristics, fuel consumption coefficient, and loading rate characteristics of each ship type. Through this, even with the same reduction amount, the relative improvement effect in the corresponding ship type can be objectively compared.

[0172] In addition, the effectiveness indicator unit (330) can convert and store the reduction effect resulting from the application of eco-friendly technology into a unit-based indicator rather than a simple emission reduction amount standard. For example, by applying standards such as CO₂ emissions per ton-mile, emissions per passenger, and emissions per transport energy, it is possible to conduct a comprehensive performance evaluation that takes into account the operating distance and transport efficiency. Through this, the actual economic and environmental contribution of eco-friendly technology can be reflected more accurately.

[0173] In addition, the effectiveness indicator unit (330) can calculate environmental improvement performance as a weighted composite indicator. For example, by assigning a high weight to the CO₂ reduction effect and reflecting differential weights according to the level of regulation to the SO₂ or NO reduction effect, it can provide a comprehensive evaluation score that aligns with specific environmental policy goals. This can support the decision to adopt strategic technologies in response to the trend of strengthening international regulations.

[0174] In addition, the effectiveness indicator unit (330) performs a function of tracking changes in indicators over time, thereby monitoring whether the eco-friendly performance of the vessel is being maintained or improved. For example, it may be possible to determine the environmental performance improvement index compared to the previous year, identify the stabilization period after the application of technology, and calculate the rate of performance degradation due to aging. Through this, continuous management of operational efficiency and preventive maintenance can be induced.

[0175] In addition, the effectiveness indicator unit (330) can provide the calculated performance indicators in a visualized data format to support policy agencies and shipowners in intuitively understanding them. For example, it can automatically generate graphs comparing performance indicators between ships, charts of improvement trends over time, and visualized reports of achievement rates relative to targets. This can be directly utilized for renewing eco-friendly certifications, verifying policy support, and reporting environmental performance.

[0176] In addition, the effectiveness indicator unit (330) can generate a performance grade indicator that can be linked to the incentive payment conditions or certification renewal conditions of the policy agency, and can automatically determine whether policy support requirements are met based on changes in performance grade.

[0177] In addition, the effectiveness indicator unit (330) includes a normalization function that applies a correction coefficient for the influence of route characteristics and weather conditions to ensure fair comparison between ships, thereby ensuring equity in performance evaluation between ships with different actual operating environments.

[0178] In addition, the effectiveness indicator unit (330) can support maintenance decision-making, such as detecting performance inflection points based on long-term performance data and predicting the timing of technology upgrades.

[0179] In this way, the effectiveness indicator unit (330) can complete a data-based eco-friendly ship performance evaluation system by normalizing the quantitatively derived environmental impact reduction performance according to ship size and operation characteristics and converting it into a key evaluation indicator that can objectively compare environmental performance among various ships.

[0180] The above information display unit (400) can classify and display at least one of the policy support project participation information and eco-friendly technology application performance information based on the full-cycle history information managed by the full-cycle history management unit (200) according to the display request conditions.

[0181] To this end, the information display unit (400) may include at least one of an eco-friendly performance display unit (410) and a group-specific information provision unit (420), as shown in FIG. 6.

[0182] The above-mentioned eco-friendly performance display unit (410) can visualize full-cycle history information by corresponding to at least one of eco-friendly technology items, application time, and vessel.

[0183] More specifically, the eco-friendly performance display unit (410) can provide visualized information on the application status of eco-friendly technology and changes in environmental performance for each vessel based on the full-cycle history information stored in the full-cycle history management server (10). For example, when a specific vessel is selected, the flow of the type of applied eco-friendly technology, the time of application, and the modification history can be diagrammed and displayed based on a time axis, and the user can intuitively check the performance changes resulting from the application of technology in the form of a graph or chart. Through this, continuous effectiveness before and after the application of technology can be analyzed visually, rather than performance values ​​at a single point in time.

[0184] In addition, the eco-friendly performance display unit (410) can display the performance contribution of each eco-friendly technology item separately. For example, the CO₂ reduction effect by fuel conversion technology, the NO and SO reduction effect by emission reduction device, and the fuel efficiency improvement effect by energy efficiency technology can be expressed as individual colors, icons, or hierarchical information, allowing the contribution of each technology to environmental impact to be grasped at a glance. Through this, the ship operator can identify the technology element that contributes most to performance improvement.

[0185] In addition, the eco-friendly performance display unit (410) can display performance changes by application time in the form of cumulative performance. For example, based on the time when a specific piece of equipment is installed, a trend chart comparing the performance difference before and after that time can be automatically generated, and sections of performance degradation caused by technological obsolescence or changes in the operating environment can be visually highlighted. Through this, the time when maintenance or the introduction of additional technology is necessary can be identified early.

[0186] In addition, the eco-friendly performance display unit (410) can provide map-based, table-based, or ranking-based display functions by normalizing performance indicators for each vessel according to the same standard so that multiple vessels can be selected for comparative analysis. For example, high-performance and low-performance vessels can be visualized by comparing the environmental performance of a group of vessels operating on the same route, which can be utilized in establishing an overall operation strategy for the shipping company.

[0187] In addition, the eco-friendly performance display unit (410) can provide a function to automatically configure and download a comprehensive report including performance indicators, emission comparison data, and reduction effects to support the generation of reports to be provided to policy agencies or research institutions. Through this, performance evaluation data for eco-friendly ship support projects can be systematically secured.

[0188] In addition, the eco-friendly performance display unit (410) may include an information security system that differentiates the scope of information provision according to the access rights of the user terminal (40), thereby protecting sensitive information while making essential information available. For example, a policy agency user can check the entire history and comparative analysis data, while a general shipowner can only check the performance data of the vessel they have registered.

[0189] In addition, the eco-friendly performance display unit (410) can automatically generate and provide certification certificates, eco-friendly performance result reports, and policy verification data in a format that can be submitted, and the time of report generation and submission history can be recorded together.

[0190] Additionally, the eco-friendly performance display unit (410) can visually display a warning message or provide immediate notification to the operator when a rapid trend of performance change, signs of technical failure, or a trend of increasing emissions is detected.

[0191] In this way, the eco-friendly performance display unit (410) provides various visualization functions that analyze full-cycle history information, thereby conveying the results of eco-friendly technology application as intuitive and reliable information, and actively supporting ship operation and policy-based decision-making.

[0192] The above group-specific information provision unit (420) can display information visualized by the eco-friendly performance display unit (410) by applying user-customized display rules to correspond to at least one of the shipowner, shipping company, and operator groups.

[0193] More specifically, the group-specific information provision unit (420) can display the visualization information generated by the eco-friendly performance display unit (410) in a customized manner, categorized according to the characteristics of user groups such as shipowners, shipping companies, and operators. At this time, the group-specific information provision unit (420) can set the display priority, detailed data exposure level, and information access rights for each group, taking into account that the scope of information and the method of expression required by each user group differ depending on the business purpose. For example, shipowners can check key information such as the overall environmental performance and certification maintenance status of the vessels they own, while operators can check real-time operational performance and data.

[0194] In addition, the group-specific information provision unit (420) can apply different information screen configuration methods depending on the user group. For shipping companies, since they need to compare the entire fleet and establish an operation strategy based on performance evaluation results, a performance comparison dashboard between ships can be provided as the default screen. On the other hand, for ship operators, the interface can be configured so that they can prioritize checking operational indicators such as real-time operation efficiency, status of applied technology, and changes in emissions of a single ship. Through this, customized information services optimized for the performance of tasks by each user can be provided.

[0195] In addition, the group-specific information provision unit (420) may apply information de-identification and phased disclosure methods according to user roles and authority. For example, it may provide the entire full-cycle history information and performance analysis results to users of classification societies or policy organizations, but may restrict general users to providing only summary indicators that do not include sensitive information. This allows for achieving a balance between data usability and information security requirements.

[0196] In addition, the group-specific information provision unit (420) can provide a notification function based on specific events. For example, when events such as performance degradation, scheduled certification expiration, or an increasing trend in emissions are detected, the information can be immediately provided to user groups that need it, so that follow-up actions can be taken quickly. This ensures the immediacy of environmental performance maintenance.

[0197] In addition, the group-specific information provision unit (420) can provide a reporting function tailored to the performance evaluation requirements of policy agencies. For example, it can automatically organize and submit reports such as verification of the effectiveness of eco-friendly technologies applied according to government support projects, and rankings of environmental performance by shipping company or vessel. Through this, policy-related supporting data can be efficiently secured and the administrative burden reduced.

[0198] In addition, the group-specific information provision unit (420) can support various outputs, such as a web-based interface, mobile UI, and API responsive data, depending on the display environment of the user terminal (40). This improves user accessibility and supports rapid decision-making at the ship operation site.

[0199] In addition, the group information provision unit (420) can automatically adjust the scope of data anonymization, specific item masking, and information disclosure according to user grade by applying personal information protection regulations and ship operation secret protection policies.

[0200] In addition, the group-specific information provision unit (420) can provide a role-based user interface, such as providing integrated performance information by region and ship type to policy agency users and providing summary indicators by ship to general users.

[0201] In this way, the group-specific information provision unit (420) can maximize the utilization value of full-cycle-based environmental performance information and simultaneously improve the sustainability of ship operations and policy linkage effects by optimizing and displaying the same eco-friendly performance information according to the purpose and authority of each user group.

[0202] The above information linkage control unit (500) can receive an external request for full-cycle history information and verify the authentication information of the requesting entity and the scope of the request for provision to determine whether to approve it, and if approved, it can control at least one of the provision items and provision methods of the full-cycle history information provided to the information display unit (400) or the external linkage system (30).

[0203] More specifically, when a request for provision is input from an external agency or user terminal (40) regarding the full-cycle history information stored in the full-cycle history management server (10), the information linkage control unit (500) can verify the access rights of the requesting entity and determine the scope of information that can be provided. In this process, the information linkage control unit (500) can verify user identification information, certificate-based access rights, policy agency designation rights, and ownership information of ship personnel to determine first whether the request for provision is legitimate. Through this, data leakage and unauthorized access can be prevented, and the legal consistency of information provision can be ensured.

[0204] Additionally, the information linkage control unit (500) can select items to be provided to suit the purpose of information utilization for each requesting entity. For example, in the case of a policy agency, extensive information such as the entire full-cycle history or the results of effectiveness analysis may be provided, whereas for general shipowners, only information related to their own vessels may be provided in a limited manner. The scope of such provision is set differentially based on the certification grade, user group type, and security grade.

[0205] Additionally, when the information linkage control unit (500) determines permission to provide, it may provide visualized information through the information display unit (400) or transmit it to an external linkage system (30) in a machine-readable data structure, selecting at least one of these methods. For example, it may control the provision method suitable for the purpose of the request among a dashboard method based on analysis results, a standard API response method, and a report download method. Through this, full-cycle information utilization can be efficiently carried out in various institutional and system environments.

[0206] In addition, the information linkage control unit (500) can automatically apply security policies, such as de-identification of personal information, masking of non-public items related to technical equipment, and limited disclosure of policy support linkage information, by considering the sensitivity level of the information provided. Therefore, legal regulations and security requirements can be satisfied even while providing information.

[0207] In addition, the information linkage control unit (500) can maintain log records regarding the time of information provision, the target of provision, the method of provision, and the items of provision, thereby enabling post-audit tracking. Through this, transparency of the information provision process is ensured, and the cause can be identified immediately in the event of unauthorized access or inappropriate use of information.

[0208] Additionally, the information linkage control unit (500) can ensure safe information linkage by automatically stopping the provision procedure and sending a notification or warning if an error occurs during information provision or if an illegal access attempt is detected. If necessary, it may require the relevant external system or user terminal (40) to re-implement the security policy or impose an additional authentication procedure.

[0209] In this way, the information linkage control unit (500) can perform the role of a key security gateway that controls the full-cycle history information so that it can be utilized externally in a stable and reliable manner through functions such as verifying authority for external provision requests, controlling provision items, managing information security, and managing provision history.

[0210] Additionally, when an external provision request is input from a third-party certification body or classification society inspection body, the information linkage control unit (500) can restrict the purpose of access and keep a record so that the provided information is used only for verification and audit purposes.

[0211] Additionally, the information linkage control unit (500) may apply different levels of encryption to transmitted data according to the security risk of the external linkage system (30), and may apply double encryption or secure channel communication to important information.

[0212] According to the present embodiment, by integrally managing data generated throughout the entire lifecycle of an eco-friendly vessel, from the design stage to construction, operation, and maintenance, the performance of applying eco-friendly technology can be calculated in an objective and highly reliable form. Through this, the environmental performance of the vessel can be systematically evaluated to verify the actual greenhouse gas emission reduction effect, and the economic and policy value of introducing eco-friendly technology can be clearly presented.

[0213] Furthermore, by collecting information generated during ship operations in real time and automatically quantifying emission calculations and environmental impact analyses, environmental improvement performance can be continuously tracked and managed by ship and operating conditions. This enables the early identification of performance degradation or maintenance needs for eco-friendly technologies and supports decision-making aimed at improving ship operational efficiency.

[0214] Furthermore, according to this embodiment, since environmental performance evaluation data can be automatically generated in accordance with standards required by policy agencies, it becomes easier to simplify eco-friendly certification procedures and prepare supporting data for policy support. This can alleviate the administrative burden of investing in eco-friendly technologies and strengthen the incentive for shipowners and shipping companies to participate in policy-making.

[0215] Furthermore, since environmental indicators can be standardized to enable comparisons between vessels of different types, operating environments, and sizes, it becomes possible to establish fleet-level eco-friendly operational strategies and manage vessels based on performance. This allows shipping companies to continuously improve the environmental efficiency of their entire fleet.
