Description

Technical Field

[0002] Currently, hull structure data, equipment data, piping and cable data during the ship design phase are generated into electronic data using 3D models. However, during the actual construction phase, these data require manual on-site inspection and reporting, primarily resulting in paper-based data. Furthermore, the inspection and reporting process involves multiple parties working together in harsh environments, leading to low efficiency. Once a ship has passed inspection and commenced operation, the relevant operational data often belongs to the ship operator. Data from the equipment's operation is not fed back to the owners during the design and construction phases, making it impossible to predict the lifespan and potential failures of the hull structure and equipment in advance. Additionally, annual ship inspections also require manual on-site inspection and reporting, disrupting normal ship operations.

[0027] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 7 As shown, this application provides a remote ship inspection system, including a user interaction platform, a model design server, data acquisition equipment, and a storage and data processing platform. The user interaction platform is used to provide an interactive interface for querying and displaying data; the model design server is used to store the hull structure model, equipment model, pipeline model, and cable model during the ship design phase; the data acquisition equipment is used to collect hull structure data, pipeline data, and cable data during the ship construction phase, and to collect operational hull structure data, operational equipment data, operational pipeline data, and operational cable data during the ship operation phase; the data output terminal of the storage and data processing platform is connected to the user interaction platform. The platform has a communication connection, with its data input end communicating with the model design server, data acquisition equipment, and ship equipment.

This eliminates the need for on-site inspections, resulting in high inspection efficiency and no impact on the ship's subsequent normal operation.

[0029] The remote ship inspection system provided in this application can centralize relevant structural data, equipment commissioning and operation data, and equipment operation data from the ship design, construction, and operation phases on a storage and data processing platform. This allows surveyors or ship owners to remotely view the ship's structural data, equipment commissioning and operation data, and equipment operation data through a user interaction platform, without the need for on-site inspection. This not only improves inspection efficiency but also ensures normal operation during the ship's operational phase.

[0030] In addition, by centralizing structural data and equipment operation data during the ship's operation phase into the ship's remote inspection coefficient, it is easier to update the design model and also to enable surveyors or ship owners to make advance predictions on equipment operation and maintenance and hull structural replacements, thereby improving the safety of ship operation.

[0031] In some embodiments, the data acquisition device includes radar, thickness gauge, drone, and / or camera. For example, the radar may be a lidar, and the camera may be a wide-angle camera or a panoramic camera.

[0032] like Figures 1 to 2As shown, the storage and data processing platform includes a model generation module. The model generation module is used to generate a corresponding digital twin model of the ship construction stage based on the structural data of the ship construction stage collected by the data acquisition equipment, and to generate a corresponding digital twin model of the ship operation stage based on the structural data of the ship operation stage collected by the data acquisition equipment.

[0033] During the shipbuilding and inspection reporting phase, a user interaction platform and a storage and data processing platform can be used to compare and register the structural digital twin model from the shipbuilding phase with the corresponding model from the design phase, thereby enabling remote structural inspection reporting. Furthermore, by utilizing the storage and data processing platform to access equipment commissioning and operation data, and by reviewing the relevant parameters of this data, it can be determined whether the equipment commissioning results meet the requirements, thus completing the remote equipment commissioning and operation inspection reporting.

[0034] During the ship's operation phase, the digital twin model of the structure during the operation phase can be compared and registered with the corresponding model in the design phase using a user interaction platform and a storage and data processing platform. This allows for remote annual inspections and records of the wear and tear of the relevant structures during operation, serving as a reference factor for subsequent design improvements.

[0035] In some embodiments, the storage and data processing platform further includes a first data processing module, which is used to compare the model data of the structural digital twin model during the ship construction phase with the model data of the data storage module during the design phase. During actual inspection, this first data processing module can be used to compare the model data of the structural digital twin model during the ship construction phase with the model data of the data storage module during the design phase, and automatically generate a list of discrepancies for surveyors or shipowners to review and compare.

[0036] In some embodiments, the storage and data processing platform includes a second data processing module, which is used to compare the model data of the structural digital twin model during the ship's operation phase with the model data of the structural digital twin model during the ship's construction phase. During actual inspection, this second data processing module can be used to compare the model data of the structural digital twin model during the ship's operation phase with the model data of the data storage module during the design phase, and automatically generate a list of discrepancies for surveyors or shipowners to review and compare.

[0037] Continue as Figures 1 to 2 As shown, the storage and data processing platform also includes an equipment data comparison module. This module compares the data from the equipment operation data storage module during the operational phase with the data from the equipment commissioning operation data storage module during the construction and acceptance phase. During the annual inspection during the operational phase, the storage and data processing platform can be used to retrieve both the equipment commissioning operation data and the equipment operation data to compare the equipment's operational status and complete the equipment inspection.

[0038] like Figures 2 to 3 As shown, the storage and data processing platform includes a design phase data storage module. This module is communicatively connected to the model design server and is used to store and retrieve hull structure models, equipment models, pipeline models, and cable models from the ship design phase. In some embodiments, the design phase data storage module and the model design server are communicatively connected via a land-based network.

[0039] During the ship design phase, 3D modeling software is used to model hull structural data, including structural materials, plate thickness, weight, structural dimensions, weld length, maintenance access, and other information. Equipment data, including equipment dimensions, manufacturer, equipment parameters, maintenance cycles, operation manuals, sensor parameters, and other information, is also modeled. Pipelines and cables serving the equipment systems, including pipe and cable materials, dimensions, and routing, are also modeled. Through the modeling of the above data, all information in the design phase can be presented in a visual form within the 3D model through a user interaction platform. The above 3D model data is then stored in the design phase data storage module of the storage and data processing platform.

[0040] like Figure 4 Combination Figure 2 As shown, the storage and data processing platform includes a structural data storage module for the construction and inspection stage. This module is communicatively connected to a data acquisition device and is used to store and retrieve construction hull structure data, construction equipment data, construction pipeline data, and construction cable data during the ship construction stage. In some embodiments, the structural data storage module for the construction and inspection stage and the data acquisition device are communicatively connected via a ship network.

[0041] During the shipbuilding phase, data acquisition equipment is used to collect actual hull structure data, equipment size data (physical parameter data such as the shape and size of the equipment), pipeline data, and cable data, forming hull structure data, equipment data, pipeline data, and cable data. This data is then transmitted through the ship's network to the structural data storage module of the construction and acceptance phase of the storage and data processing platform.

[0042] In practical applications, during the shipbuilding phase, for areas requiring precise quantitative data, data acquisition equipment such as drones, LiDAR, and thickness gauges are used to conduct on-site laser scanning and video recording of relevant data from the completed ship. This data is then transmitted back via network and stored in a data processing platform. After processing, a digital twin model of the ship's structure, equipment, pipelines, and cables is generated. Through a user interaction platform, this model can be compared and registered with the 3D model data from the design phase. The system directly outputs structural construction deviation data and a defect list for remote inspection. For areas where precise quantitative data is not required, drones and cameras are used to conduct on-site laser scanning and video recording of relevant data from the completed ship. Surveyors then use VR equipment to construct a virtual cabin simulation environment for remote inspection.

[0043] like Figure 5 Combination Figure 2 As shown, the storage and data processing platform includes a data storage module for equipment commissioning and operation during the construction and acceptance phase. This data storage module is connected to the ship's equipment and is used to store and retrieve equipment commissioning and operation data during the ship's construction phase.

[0044] In some embodiments, the equipment commissioning and operation data storage module during the construction and acceptance phase communicates with the ship's equipment via the ship's network. During the ship's construction phase, the ship's equipment is commissioned and operated. By collecting the main parameters of all equipment on the ship, processing the data, and then sending it through the ship's network to the equipment commissioning and operation data storage module of the construction and acceptance phase storage and data processing platform.

[0045] like Figure 6 Combination Figure 2 As shown, the storage and data processing platform includes an operational phase structure data storage module. This module is communicatively connected to the data acquisition equipment and is used to store and retrieve operational hull structure data, operational equipment data, operational pipeline data, and operational cable data during the ship's operational phase. In some embodiments, the operational phase structure data storage module and the data acquisition equipment are communicatively connected via a maritime satellite network.

[0046] During the ship's operation phase, data acquisition equipment is used to collect data on the ship's hull structure, equipment dimensions (physical parameters such as the shape and size of the equipment), pipelines, and cables, forming operational hull structure data, operational equipment data, operational pipeline data, and operational cable data. This data is then transmitted via a maritime satellite network to the operational phase structure data storage module of the storage and data processing platform.

[0047] In practical applications, during the ship operation phase, data acquisition equipment such as drones, lidar, and thickness gauges are used to perform on-site laser scanning and video recording of ship-related data. After data collection and transmission via network, this data enters the storage and data processing platform. After data processing, a digital twin model of the ship's structure, equipment, pipelines, and cables during the ship operation phase is generated. This model is then compared and processed with data from the design phase and equipment commissioning and operation through a user interaction platform, providing feedback to predict and provide early warnings for the ship's regular maintenance, inspection, and structural and equipment lifespan.

[0048] like Figure 7 Combination Figure 2 As shown, the storage and data processing platform includes an operational phase equipment operation data storage module. This module is communicatively connected to the ship's equipment and is used to store and retrieve equipment operation data during the ship's operational phase. Specifically, the equipment operation data during the ship's operational phase includes normal operation data and equipment failure data. In some embodiments, the operational phase equipment operation data storage module communicates with the ship's equipment via a maritime satellite network.

[0049] During the ship's operation phase, key parameters of all equipment operating on board are collected. After data processing, the data is transmitted via a maritime satellite network to the operational equipment data storage module of the storage and data processing platform.

[0050] In summary, the remote ship inspection system provided in this application compares the digital twin model generated from data collected during the ship's construction phase with the 3D model data from the design phase. The system directly outputs construction deviation data and a defect list, enabling remote inspection. Data acquisition equipment generates a video stream from the collected inspection data, allowing surveyors or ship owners to conduct remote inspections using VR devices. Furthermore, by collecting operational data such as equipment operation and structural wear during the operational phase and transmitting it back to the ship's digital twin model for updates, the system enables prediction and early warning of regular maintenance, inspections, and structural and equipment lifespan for ship operation.

[0051] Based on the aforementioned remote ship inspection system, this application also provides a remote ship inspection method, comprising the following steps: Design phase: Using the 3D modeling software of the model design server, the ship structure data, equipment data, pipeline data and cable data are modeled to form the ship structure model, equipment model, pipeline model and cable model; Construction and inspection stage: Based on the user interaction platform, the storage and data processing platform is used to call up the construction hull structure data, construction equipment data, construction pipeline data, construction cable data, and equipment commissioning and operation data, and compare them with the model data in the design stage to complete the remote inspection. Operational Phase: Based on the user interaction platform, the system utilizes the storage and data processing platform to access operational hull structure data, operational equipment data, operational pipeline data, operational cable data, and equipment operation data. This data is then compared with the model data from the design phase and with the equipment commissioning and operation data to complete the remote annual inspection.

[0052] In some embodiments, during the design phase, 3D modeling software is used to model ship structure data, including structural material, plate thickness, weight, structural dimensions, weld length, maintenance access, and other information; equipment data, including equipment dimensions, manufacturer, equipment parameters, maintenance cycle, operation manual, sensor parameters, and other information, is modeled; and pipelines and cables serving the equipment system, including pipeline and cable material, dimensions, and routing information, are modeled. Through the modeling of the above data, all information in the design phase can be presented in a visual form in the 3D model through a user interaction platform. The above 3D model data enters the design phase data storage module in the storage and data processing platform.

[0053] In some embodiments, the construction inspection stage includes the following steps: the storage and data processing platform forms a structural digital twin model of the ship construction stage based on the construction hull structure data, construction equipment data, construction pipeline data, and construction cable data collected by the data acquisition equipment; the equipment commissioning and operation data obtained from the commissioning and operation of the ship equipment is input into the structural digital twin model of the ship construction stage, and compared with the model data in the design stage to complete the remote inspection.

[0054] During the construction phase, data collection is conducted on the actual hull structure, pipelines, cables, and equipment dimensions. This is achieved by establishing a wired and / or wireless ship network within the vessel. For areas requiring precise data quantification, such as hull structure dimensions, equipment passageways, and equipment dimensions, data acquisition equipment such as drones, LiDAR, and thickness gauges is used to perform on-site laser scanning and imaging of the completed vessel. This data collection process generates a "point cloud." This data then passes through the ship network and enters the structural data storage module for the construction and acceptance phase within the storage and processing platform. The platform then processes the data to generate the final data. The system generates a structural digital twin model of the ship's hull, pipelines, and cables during the shipbuilding phase. Using coarse and fine registration and difference compensation algorithms, the system compares and registers this structural digital twin model with the 3D model from the design phase through a user interaction platform. The system directly outputs construction deviation data and a defect list, enabling remote inspection of all projects. For areas that do not require precise quantitative data, data captured by drones, wide-angle cameras, or panoramic cameras is transmitted back via the network to a storage and data processing platform to generate a panoramic video stream. Surveyors or ship owners can then use VR equipment for immersive inspections and remote reporting.

[0055] During the construction phase, it is necessary to collect commissioning and operation data of the ship's equipment. This includes collecting image data, temperature, pressure, vibration, and liquid level data of all ship equipment, such as navigation systems, main and auxiliary engines and auxiliary equipment, pumps, valves, and liquid tanks. This data is then transmitted via wired and / or wireless ship networks to the equipment commissioning and operation data storage module of the construction and inspection phase storage and data processing platform. After data format processing, edge preprocessing, data mapping, and driving, the corresponding equipment commissioning and operation data is transmitted to the structural digital twin model of the ship's construction phase via wired and / or wireless networks built within the ship. This data is then compared and registered with the 3D model data from the design phase. The system directly outputs deviation data and a list of defects during equipment commissioning and operation, enabling remote inspection.

[0056] In some embodiments, during the operation phase, the following steps are included: the storage and data processing platform forms a structural digital twin model of the ship during the operation phase based on the operational hull structure data, operational equipment data, operational pipeline data, and operational cable data collected by the data acquisition equipment; the equipment operation data is input into the structural digital twin model of the ship during the operation phase, and compared with the model data in the design phase, as well as with the equipment commissioning and operation data, to complete the remote annual inspection.

[0057] During the operational phase, laser scanning can be performed using drones, lidar, thickness gauges, wide-angle cameras, or panoramic cameras to collect data on structures, pipelines, and cables, while also packaging and processing data on the normal operation and malfunctions of equipment on board.

[0058] The remote ship inspection system and method provided in this application, compared to the traditional "on-site centralized verification" inspection method, uses 3D modeling software to create a digital twin model of relevant data from the ship design phase. For the inspection parts requiring precise quantitative data, data acquisition devices collect and process the relevant data of the completed ship during the construction phase, generating a digital twin model. This digital twin model is then compared and calibrated with the 3D model from the design phase. The system directly outputs construction deviation data and a defect list, enabling remote inspection. For the inspection parts that do not require precise quantitative data, data is collected by data acquisition devices, stored and processed by the system, and surveyors or shipowners can conduct remote inspections using VR equipment. Through these two methods, remote ship inspection is achieved, eliminating the need for on-site inspections. During the operational phase, operational data such as equipment operation and structural wear are collected and transmitted back to the ship's digital twin model for updates, enabling prediction and early warning of regular maintenance, inspections, and structural and equipment lifespan. The implementation of this system can significantly enhance the intelligence of ships. Compared to shipyards that deliver more than 30 ships a year, which charge 800,000 to 1 million yuan per ship for inspection, this can save 24 million to 30 million yuan in inspection fees.

[0059] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
