Description

Device for providing information on ship maneuverability performance and method for controlling the same

[0001] The present invention relates to a device for providing information on the maneuvering performance of a ship and a method for controlling the same, and more specifically, to a device for providing information on the maneuvering performance of a ship that simulates maneuvering performance for items included in a ship's maneuvering booklet and provides results for each item.

[0002] To ensure the operational safety of vessels, the International Maritime Organization (IMO) sets forth strict regulations regarding ship maneuverability. In particular, IMO RESOLUTION A.601 details the items required to create a Maneuvering Information Booklet (MIB), which evaluates a ship's maneuverability and provides maneuvering information based on this evaluation.

[0003] Accordingly, the shipyard has prepared the relevant booklet based on the results of various vessel maneuvering performance tests and simulations, and has submitted it as a reference for vessel operations.

[0004] A maneuvering booklet is an important document that records key maneuvering performance data of a vessel; it is essential for predicting how the ship will react to various conditions it may encounter during navigation and for taking appropriate measures.

[0005] The booklet contains test results regarding various maneuverability performances of the vessel, such as course-changing ability, turning radius, and stopping capability, enabling operators (users) to plan and execute safe navigation based on this information. However, since this document has traditionally been provided in booklet form, it could cause several difficulties regarding the accessibility and usability of the information.

[0006] First, as the vast amount of information was contained in the booklet, it was difficult for users to immediately find the information they needed. In rapidly changing situations during ship operation, specific maneuvering performance data must be checked quickly, but the booklet format was sometimes unable to adequately meet these requirements.

[0007] Furthermore, since the information recorded in the booklet is mostly based on test results under limited conditions, there were limitations in predicting ship performance in real-time changing operating environments or hypothetical scenarios.

[0008] These problems can impair the efficiency and safety of ship operations and are increasing the demand for systems that reflect modern, complex, and diverse operating conditions.

[0009] In particular, there is a demand for an approach that allows easy retrieval of maneuvering performance data relevant to real-time situations, in addition to the fixed information recorded in booklets, and there is a growing need for a system that can quickly provide performance information under various operating conditions.

[0010] The present invention aims to provide a system that enables a ship operator to quickly and intuitively search for necessary maneuvering performance data by digitizing a maneuvering booklet to solve the problems described above.

[0011] In addition, the present invention enables the automatic calculation and provision of ship maneuvering performance information through a simulation that reflects current operating conditions in real time.

[0012] Furthermore, the purpose is to predict the maneuvering performance of a vessel suitable for the given conditions when a user inputs a hypothetical situation, and to provide this information quickly.

[0013] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0014] A ship maneuvering performance information providing device according to one embodiment of the present invention may include: a booklet item selection unit that receives a target booklet item to be verified from a user; a user input unit that receives reference information related to a ship from a user; a control unit that determines the information type of the reference information, executes a maneuvering performance simulation based on the determined information type, and derives a result value included in the ship maneuvering performance information through the maneuvering performance simulation; and a booklet item display unit that displays a target result value related to the target booklet item among the derived result values ​​on a screen.

[0015] It may further include an information output unit that outputs at least one of weather information, terrain information, or character information.

[0016] The above information type may include at least one of a basic information type, a current state type, or a virtual setting type.

[0017] The system further includes a storage unit that stores the contents of the ship's maneuvering booklet in a database, and the control unit can derive the result value based on the contents of the maneuvering booklet without executing the maneuvering performance simulation when the determined information type is the basic information type.

[0018] The control unit above can determine the information type as the basic information type when the reference information is not input and the target booklet item is selected.

[0019] The control unit further includes a monitoring unit that monitors at least one of static data including major specifications of the vessel; dynamic data including at least one of the vessel's course to land, speed to land, or bow direction; navigation data including draft or speed; or environmental data including weather conditions such as wind speed or topographic information such as water depth. When the determined information type is a current state type, the control unit can execute the maneuvering performance simulation based on data received from the monitoring unit.

[0020] The control unit can execute a maneuvering performance simulation based on the contents of the reference information and the data of the monitored vessel when the determined information type is a virtual setting type.

[0021] The reference information of the above virtual setting type may include at least one of the vessel's draft, speed, water depth, location on a map, or environmental data that the user arbitrarily inputs.

[0022] The location on the map above may be reference information received by selecting a location from a nautical chart displayed in the input section or by entering latitude or longitude.

[0023] A method for providing information on the maneuverability performance of a ship, which is another embodiment of the present invention, comprises the steps of: selecting a target booklet item to be verified; and inputting reference information related to the ship.

[0024] The method may include: a step of determining the information type of the reference information; a step of executing a maneuvering performance simulation based on the information type; a step of deriving a result value included in the maneuvering performance information of the vessel through the maneuvering performance simulation; and a step of displaying a target result value related to the target booklet item among the derived result values ​​on a screen.

[0025] According to one embodiment of the present invention, by digitizing the maneuvering booklet, the ship operator can quickly search for necessary maneuvering performance data, thereby increasing the convenience of operation.

[0026] In addition, simulations reflecting real-time operating conditions allow for the prediction of ship maneuverability even in changing situations, thereby aiding in safe navigation.

[0027] Furthermore, by inputting virtual operating conditions, maneuvering performance under those conditions can be predicted in advance, allowing for more flexible operation planning tailored to various scenarios.

[0028] Further scopes of the applicability of the present invention will become apparent from the following detailed description. However, since various changes and modifications within the spirit and scope of the present invention are clearly understood by those skilled in the art, specific embodiments, such as the detailed description and preferred embodiments of the present invention, should be understood as being given merely as examples.

[0041] The present invention relates to a supply device used not only during sea trials of a ship but also during constant operation.

[0042] FIG. 1 is a block diagram of a ship maneuvering performance information providing device according to one embodiment of the present invention.

[0043] The ship maneuverability performance information providing device (100) (hereinafter, providing device) according to the present invention may include a booklet item selection unit (10), a user input unit (20), a display unit (30), an information output unit (40), a control unit (50), a monitoring unit (60), a storage unit (70), etc. The configuration of the providing device (100) is not limited thereto and may include fewer or more configurations.

[0044] The booklet item selection unit (10), user input unit (20), display unit (30), and information output unit (40) according to the present invention are each provided separately to receive information from the user or output information, but are not limited thereto and can be provided as a single module (D) (e.g., a touchscreen).

[0045] For example, the user input unit (20) may be composed of a keyboard, separate buttons, etc., provided on the vessel, and may be provided as a touch screen as a module integrated with the display unit (30). The touch screen may be a fixed type or a movable type.

[0046] Hereinafter, as an example, a case is described in which a booklet item selection unit (10), a user input unit (20), a display unit (30), and an information output unit (40) are integrally provided on a touch screen.

[0047] The booklet item selection unit (10) can receive a target booklet item to be checked from the user. As described above in the background art, the booklet refers to a maneuvering booklet of a ship, and is a document that evaluates the ship's maneuvering performance and provides maneuvering information based thereon, and includes multiple items related to various maneuvering performances of the ship. This will be described in detail later with reference to FIG. 3.

[0048] The user input unit (20) may be an input device that receives standard information related to the ship from the user. That is, the user input unit (20) is a component in the present invention that allows the user to input standard information related to the ship, and may play the role of receiving operational status or standard information of the ship.

[0049] The user input section (20) is an interface for providing specific data regarding the maneuvering performance items that the user wishes to check, and can receive input such as the condition of the ship, the current environment, or parameters related to operation. This will be described later with reference to FIG. 4.

[0050] These input data can be used as basic information for performing simulations or additional analysis in the control unit (50).

[0051] The user input unit (20) can be implemented as an input device such as a physical keyboard or a touchscreen and can be designed so that the user can easily input data.

[0052] The display unit (30) is a component that displays the result derived from the control unit (50) on a screen, and can be implemented in the form of a display module or a touchscreen module. This will be described in detail later with reference to FIG. 2.

[0053] The display unit (30) provides data visually so that the operator (user) can check the necessary information, and displays various information according to the operation status or set conditions. Through this, the operator can visually access the data provided by the system and select or refer to the necessary control performance items.

[0054] The information output unit (40) is a component that outputs the operation status or other related data from the system and can provide various data so that the user can check the information.

[0055] The information output unit (40) can output data such as weather information, terrain information, and vessel information, and can additionally output other types of data as needed. The output information may include important data that helps the operator understand the current situation and take appropriate measures.

[0056] The information output unit (40) can be implemented as a display module, printer, or other output device, and is not limited thereto but can be implemented in various ways to suit the requirements of the system.

[0057] The control unit (50) can control the overall operation of the device and perform the role of processing various input information and data to derive results.

[0058] The control unit (50) can process data input from the system and, based on this, execute a simulation to derive results. The control unit (50) can analyze various data, such as operational status information and reference information, and calculate the ship's maneuvering performance information based on this.

[0059] In addition, the control unit (50) can further analyze data through machine learning and derive optimal results suitable for the operating state, and this function is not limited thereto and may include various data processing methods.

[0060] The control unit (50) can be implemented in various ways and may be composed of a CPU-based system, a GPU-based parallel processing system, a hardware accelerator such as an FPGA, a distributed computing system, etc. These implementation methods can be selected according to the system requirements and data processing needs.

[0061] The monitoring unit (60) is a component that detects the ship's operating status in real time and collects various types of data. The monitoring unit (60) may include static data such as the ship's main specifications, and monitors the ship's physical characteristics or structural information to provide basic data necessary during operation.

[0062] In addition, it can detect dynamic data that changes in real time, such as the ship's course, speed, and heading, thereby providing accurate information regarding the ship's position, speed, and direction in real time. Navigation data includes navigation-related information such as the ship's draft and speed, and this data plays an important role in operation.

[0063] In addition, environmental data includes information such as weather conditions or topographical information; for example, by monitoring data such as wind speed or water depth, information regarding weather conditions and the marine environment during operation can be provided.

[0064] These various data are monitored in real time and transmitted to the control unit (50), and the control unit can perform a control performance simulation based on the data.

[0065] In addition, the monitoring unit (60) can be linked with various sensors within the vessel to collect dynamic information and environmental information of the vessel, and based on this, can provide accurate data necessary for the operator's decision-making.

[0066] The monitoring unit (60) can be integrated with various equipment such as a location information system, weather sensor, speedometer, gyroscope, etc., and can be expanded to measure additional information as needed.

[0067] The monitoring unit (60) can provide data necessary for the operator's decision-making by reflecting various situations during operation, and the types of data are not limited to this and can monitor additional information according to system requirements.

[0068] The storage unit (70) stores data collected from the monitoring unit (60) for a certain period of time and may store all contents of the real-time collected navigation status information and the ship's maneuvering booklet in a database. The storage unit (70) may store static data such as the ship's main specifications, dynamic data such as the course to the ground, speed to the ground, and bow bearing, navigation data related to draft or ship speed, and environmental data including weather conditions and topographic information, and this data may be used to run simulations in the control unit (50) or to provide base data for machine learning.

[0069] Additionally, the storage unit (70) stores the entire contents of the vessel's maneuvering booklet, allowing the maneuvering booklet to be stored in a database so that the operator can quickly look it up when needed. This database can serve as a basis for quickly searching for items needed during vessel operation and providing related maneuvering performance information. Through this, the operator can check the details of the booklet in real time or select data suitable for a specific situation.

[0070] Additionally, the storage unit (70) can store various computational programs, and these programs can be used for control performance simulation or analysis work performed in the control unit (50).

[0071] To elaborate further on the description of the above components in relation to one embodiment of the present invention, the following is a more detailed explanation.

[0072] The control unit (50) can receive reference information related to a vessel received from the user input unit (20) and determine the information type of the reference information. The information type of the reference information may include a basic information type, a current state type, or a virtual setting type.

[0073] In this case, the reference information may be information that serves as the basis for the maneuverability performance simulation. The reference information can be input through methods such as the user selecting a button or directly inputting data. The reference information may also include only output commands without inputting data.

[0074] The control unit (50) can execute a maneuvering performance simulation (hereinafter, simulation) based on the determined information type. For example, if the information type is determined to be a basic information type, the maneuvering performance simulation may not be executed.

[0075] For example, the reference information of the basic information type may be information already included in the maneuvering booklet. For example, the user may select and input Loaded Draft or Ballast Draft, etc.

[0076] The vessel maneuvering performance information at the above Loaded Draft or Ballast Draft is content included in the existing maneuvering booklet through a prior maneuvering performance evaluation. Generally, it includes maneuvering performance information under conditions of deep sea and no environmental loads.

[0077] As described above, the contents of the existing maneuvering booklet must be used as reference material for ship operation, and may be data already stored in the storage unit (70) of the providing device (100) prior to the delivery of the ship.

[0078] Accordingly, when a user selects a basic information type, such as Loaded Draft or Ballast Draft, and inputs it as reference information, the control unit (50) determines that it is a basic information type and can derive the corresponding content included in the maneuvering booklet as a result value without running a simulation.

[0079] In addition, if only the target booklet item is selected without inputting reference information, it is determined that reference information corresponding to the pre-configured basic information type has been entered, and the content corresponding to the basic maneuvering booklet can be derived as the result value.

[0080] Meanwhile, the control unit can display only the target result value related to the target booklet item selected by the user to verify among the derived result values ​​through the display unit. That is, it can derive result values ​​for all items of the maneuvering booklet and output only the item requested by the user.

[0081] Referring to FIG. 3 for better understanding of the explanation, a device according to one embodiment of the present invention may select and output 15 items from among the items included in a maneuvering booklet. This is merely an example, and other evaluation items for maneuvering performance may also be included.

[0082] As an example, for instance, when an operator (user) selects a stopping capability evaluation item among the booklet items as a target booklet item in the booklet item selection section and clicks the Loaded Draft button, the result value of the stopping capability evaluation of the corresponding vessel at the Loaded Draft, which is included in the content of the existing maneuvering booklet, may be displayed in the output section.

[0083] Alternatively, as another embodiment, if the operator (user) does not input reference information but selects and inputs only the item of the booklet for the stopping capability evaluation, the control unit determines that the loaded draft or ballast draft has been input, and the result of the stopping capability evaluation under the corresponding condition may be displayed on the output unit. This is merely an example.

[0084] According to another embodiment of the present invention, for example, the control unit (50) can determine the information type of reference information as the current state type and execute a simulation based on data received from the monitoring unit (60). For example, if a user presses the current state button, it can be determined as the current state type.

[0085] For example, the control unit receives static information, dynamic information, navigation information, and environmental information of the ship monitored by the monitoring unit, and can execute a simulation using this information.

[0086] The control unit (50) can perform a simulation on a selected booklet item or on all booklet items. For example, it is possible to perform a simulation on all booklet items and display only the target result value of the target booklet item.

[0087] For example, the control unit (50) can calculate the result value using the following mathematical formula.

[0088]

[0089]

[0090]

[0091] Each variable used in the above mathematical formula represents a mathematical expression of the ship's movement and external environmental factors, and can be used to analyze or predict the ship's maneuvering performance. The variables can be broadly classified into those representing the ship's motion characteristics and those representing external forces.

[0092] First, m is a variable representing the ship's motion characteristics, indicating its weight. The ship's straight-line velocity can be denoted by u, and its straight-line acceleration by u'. The lateral velocity can be denoted by v, and the lateral acceleration by v', which describes the ship's lateral movement characteristics. Additionally, the ship's yaw velocity can be denoted by r, and its yaw acceleration by r'. The ship's moment of inertia along the z-axis is expressed as I_zz, representing the inertia of the ship during rotational motion.

[0093] Next, external forces acting on a ship are classified into straight-line, transverse, and yaw directions. Forces in the straight-line direction include the force X_H due to the hull, the force X_R due to the rudder, the force X_P due to the propeller, the force X_wave due to waves, the force X_current due to currents, and the force X_wind due to wind. These represent the major factors acting when the ship moves in a straight direction.

[0094] Lateral forces include the force Y_H due to the hull, the force Y_R due to the rudder, the force Y_wave due to waves, the force Y_current due to currents, and the force Y_wind due to wind. These forces can explain the external factors when a ship moves sideways.

[0095] Finally, the yaw rotational forces include the force N_H due to the hull, the force N_R due to the rudder, the force N_wave due to waves, the force N_current due to currents, and the force N_wind due to wind. These variables numerically represent the external factors acting when a ship rotates or changes direction.

[0096] [Equation 1] describes the straight-line motion of a ship. It includes the mass and acceleration of the ship and the velocity affected by rotational motion, and the straight-line motion of the ship can be calculated by summing the forces acting in the straight direction by the hull, rudder, propeller, waves, currents, and wind.

[0097] [Equation 2] represents the transverse motion of a ship. It includes the effects of the ship's mass, transverse acceleration, and rotational motion on transverse velocity, and can show how external forces acting transversely, such as the hull, rudder, waves, currents, and wind, contribute to the ship's lateral movement.

[0098] [Equation 3] deals with the yaw rotational motion of a ship. Based on the ship's z-axis moment of inertia and rotational acceleration, the ship's rotational motion can be calculated by considering the forces acting in the direction of rotation, such as the hull, rudder, waves, currents, and wind.

[0099] These equations numerically express the effects of the external environment and the steering device when a ship moves in a straight line, transversely, or rotationally, and can be used to predict the movement of the ship under various conditions.

[0100] In addition, the control unit can provide maneuverability considering environmental conditions for all drafts between the full load draft and the ballast draft.

[0101] The maneuvering performance simulation can be executed based on the ship data received by the monitoring unit (60), the maneuvering performance calculation formula stored in the storage unit, or the reference information received from the user.

[0102] In one embodiment, for example, when an operator (user) selects an acceleration rotation evaluation item among the booklet items as a target booklet item in the booklet item selection unit and clicks the current status button, data required for the acceleration rotation evaluation simulation (e.g., ship specifications, current water depth, current ship speed, current draft, etc.) is received from the monitoring unit, a simulation is executed using the data, a result value (estimated value) of the acceleration rotation evaluation is derived through the simulation, and this can be output to the display unit (30).

[0103] Alternatively, the control unit (50) may receive data from the monitoring unit to simulate the result values ​​of all booklet items, execute the simulation, derive the result values ​​of all booklet items through the simulation, and then output only the result value for the acceleration rotation evaluation to the screen (display unit).

[0104] Through this, operators can quickly receive data necessary for decision-making that reflects the current situation.

[0105] According to another embodiment of the present invention, for example, if the information type of reference information determined by the control unit (50) is a virtual setting type, a maneuvering performance simulation can be performed based on the content of the reference information and the data of the monitored vessel.

[0106] Here, the data of the vessel being monitored may mean that it includes all the data obtained from the monitoring unit (60) described above.

[0107] At this time, the reference information of the virtual setting type above may include at least one of the draft, speed, depth, location on a map, or environmental data of a vessel that is arbitrarily entered by the user.

[0108] The above embodiment will be described in detail later with reference to FIG. 4.

[0109] FIG. 2 shows an example of a screen of a display unit (30) according to one embodiment of the present invention.

[0110] As described above, the display unit (30) may be a touch screen. For example, a single touch screen can implement the booklet item selection unit (10), user input unit (20), display unit (30), and information output unit (40).

[0111] Examples of implementation methods for each component are explained below.

[0112] The booklet item selection unit (10) can be implemented, for example, as a window of a touchscreen or display. Referring to FIGS. 2 and FIGS. 3 together, the booklet item selection unit may be configured to allow the user to select and input in a drop-down format, or to input by searching directly. This is merely an example, and in any way, it can be designed so that the user can easily select the steering performance evaluation information (including booklet items) they need.

[0113] The user input unit (20) can be implemented, for example, as a window of a touchscreen or display, with reference to FIG. 2 and FIG. 4 together. This will be described later in FIG. 4.

[0114] The display unit (30) can be implemented as a single window of a touchscreen or display. The display unit (30) can receive and display result values ​​based on input values ​​derived from the control unit (50). For example, it can display result values ​​related to booklet items selected by the user.

[0115] At this time, the result value is not simply expressed as a number or numerical value, but can be provided in a format such as a chart or graph as shown in Fig. 2.

[0116] The information output unit (40) is a component that outputs the operation status or other related data from the system and can provide various data so that the user can check the information.

[0117] The information output unit (40) can output data such as weather information (information on waves, currents, wind direction, wind speed, etc.), topographic information (water depth information, etc.), and vessel information (draft, vessel speed, etc.), and can additionally output data of other forms as needed. The output information may include data that helps the operator understand the current situation and take appropriate measures.

[0118] FIG. 3 shows an example of a booklet item selection section according to one embodiment of the present invention.

[0119] As described above, the booklet item selection unit (10) can receive a target booklet item to be checked from the user.

[0120] The booklet item selection section (10) can be configured to allow the user to select and input items in a drop-down format as shown in FIG. 3, or to input items by searching directly. This is merely an example, and in any way, it can be designed so that the user can easily select the steering performance evaluation information (including booklet items) they need.

[0121] The user can simply select a target item by clicking or touching the required target item among the booklet items listed in a drop-down format as shown in Fig. 3.

[0141] 4.2 Course-keeping Limitation - Evaluates the maximum wind speed at which a vessel can maintain its direction at a specific wind direction and rudder angle, and evaluates the leeway angle when under the influence of wind loads;

[0142] 5. Maneuvering Characteristics at Low Speed ​​– Evaluates when the vessel moves forward by inertia after stopping the engine and its direction no longer responds to rudder movements.

[0143] The above items are merely examples and may be reduced or added beyond the examples provided, depending on the need to provide maneuverability performance information for the user's operation.

[0144] FIG. 4 shows an example of a user input unit according to an embodiment of the present invention.

[0145] The user input section can be implemented, for example, as an input device and a screen. The user input section functions as an interface capable of inputting various data for the simulation of a ship's maneuvering performance.

[0146] FIG. 4 shows an embodiment in which the user input part is implemented as a touch screen or a single window.

[0147] The user input section (20) can receive standard information related to the vessel from the user. The user input section (20) can receive standard information belonging to the types of basic information (21), current status (22), and virtual setting (23).

[0148] For example, the user may click or touch the corresponding button to input the structural draft (211) included in the basic information (21) as illustrated in FIG. 4. Likewise, the user may click or touch the corresponding button to input the ballast draft (212). This is an example of an input method and may be input in various ways.

[0149] For example, if the user wants to know the maneuverability information of the ship in its current state, they can input reference information by inputting, clicking, or touching the current state (22).

[0150] Also, for example, if you want to input reference information for a virtual setting (23), you can directly input the desired data.

[0151] In order to predict operation, the operator (user) may want to obtain information on maneuverability performance at a specific draft, speed, water depth, environment, etc., rather than the current state. At this time, reference information belonging to a virtual setting type can be entered in the user input section, and with reference to FIG. 4, the desired information can be entered by directly writing it in the virtual setting (23) input field.

[0152] At this time, the reference information of the virtual setting type may include at least one of the ship's draft (231), ship speed (232), water depth (233), location on a map (235), or environmental data (234) that the user arbitrarily inputs, but is not limited thereto.

[0153] In particular, for environmental data, users may be allowed to directly select the type of variable (standard information) they wish to input, or additional windows may be created to add necessary conditions (standard information).

[0154] In addition, regarding location, the system may operate by displaying a map (nautical chart) on the screen and retrieving information about a desired location when the user selects it on the map. For example, information such as latitude, longitude, weather conditions, and water depth for the location selected by the user on the map can be transmitted from an external or internal source. Alternatively, the desired location can be entered by inputting its latitude or longitude.

[0155] According to another embodiment of the present invention, if the information type of reference information determined by the control unit (50) is a virtual setting type, a maneuvering performance simulation can be performed based on the content of the reference information and the data of the monitored vessel.

[0156] Here, the data of the vessel being monitored may mean that it includes all the data obtained from the monitoring unit (60) described above.

[0157] For example, when the user selects 'maneuvering performance at low speed' among the items in the booklet and inputs reference information such as draft (e.g., 9.5m), ship speed (e.g., 10.0Kts.), and water depth (e.g., 20m), the control unit (50) receives the data input by the user and other data (static data, dynamic data, etc.) necessary to generate the result value of 'maneuvering performance at low speed' from the monitoring unit, and then executes a simulation based on these data and derives the result value.

[0158] FIG. 5 is a flowchart of a method for providing information on the maneuverability performance of a ship according to an embodiment of the present invention.

[0159] Referring to FIG. 5, first, the user can select a target booklet item to check (S510). At this time, the user can select the target booklet item through the booklet item input section. Afterwards, the user receives a result value for the selected target booklet item.

[0160] Next, the user can input reference information related to the vessel (S520). At this time, the user can input the reference information using the user input section. The reference information can be classified into basic information type, current status type, or virtual setting status type.

[0161] Next, the control unit can determine the type of reference information entered by the user (S530). At this stage, the control unit determines whether the entered information is the current operating state or a virtual setting, etc. Through this determination of the information type, the simulation method may vary depending on the characteristics of the entered data.

[0162] Subsequently, in the maneuvering performance simulation execution (S540) step, a simulation is performed based on the input information and selected booklet items. Through the simulation, the maneuvering performance of the vessel in its current or virtual operating situation can be calculated. This calculation process may include complex numerical operations for evaluating the vessel's performance.

[0163] In the step of deriving result values ​​included in steering performance information (S550), steering performance information derived from the simulation results is calculated. This information is a specific steering performance result for an item selected by the user and can serve as data necessary during operation. Finally, in the step of displaying target result values ​​(S560), the derived result values ​​are displayed on a display unit so that the user can easily verify them.

[0164] As described above, the device and method for providing maneuvering performance information of a ship according to one embodiment of the present invention can enhance the convenience of operation by providing an access method that allows a ship operator to quickly and intuitively search for necessary maneuvering performance data and easily find maneuvering performance data suitable for real-time situations in addition to fixed information.

[0165] It is obvious to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential features of the invention.

[0166] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
