[0002] This invention relates to a technique for obtaining information related to a ship's fuel consumption. Background Technology

[0003] Patent document 1 describes a system for monitoring a ship's fuel consumption. Patent document 1 describes a fuel consumption monitoring system that calculates the instantaneous fuel consumption of the main engine based on the fuel flow rate measured by a pulse-transmitting flow meter, and displays the time-varying and cumulative changes in fuel consumption based on the instantaneous fuel consumption.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2015-85924 Summary of the Invention

[0005] The problem the invention aims to solve

[0006] A ship's fuel consumption depends on the amount of cargo it carries and the distance it travels. Therefore, in evaluating a ship's fuel consumption, fuel consumption per unit load per unit distance is more significant than the absolute value of fuel consumption. Furthermore, "fuel consumption per unit load per unit distance" means the amount of fuel required to transport a unit amount of cargo a unit distance. The unit for fuel consumption per unit load per unit distance is, for example, "ton / (ton·mile)".

[0007] In the case of the fuel consumption monitoring system described in Patent Document 1, the time-varying and cumulative absolute values ​​of the ship's fuel consumption are displayed, but the fuel consumption per unit load per unit distance is not displayed. Therefore, the user of the fuel consumption monitoring system described in Patent Document 1 cannot evaluate the ship's fuel consumption by taking into account the amount of cargo and the transport distance.

[0008] The present invention was made in view of the above circumstances, and its object is to provide a method for evaluating the fuel consumption of a ship by taking into account the amount of cargo and the transport distance.

Detailed Implementation

[0050] Figure 1 This is a diagram illustrating the structure of a ship 3 equipped with an information processing device 1 according to one embodiment of the present invention. The ship 3 is, for example, a cargo ship. The main structural elements of the ship 3 are the hull 30, bridge 31, mechanism control room 32, propulsion mechanism 33, shaft 34, propeller 35, fuel tank 36, fuel piping 37, governor 38, ballast water tank 39, flow meter 40, tachometer 41, draft gauge 42, and satellite navigation system 43.

[0051] Information processing device 1 is located on bridge 31. In addition, a touch screen display 2 is located in mechanism control room 32. The touch screen display 2 displays the same screen as that displayed on information processing device 1 and accepts user operation.

[0052] The propulsion mechanism 33 drives the propeller 35 to rotate by driving the shaft 34, thereby generating thrust. The fuel tank 36 contains fuel, and the fuel pipe 37 forms a supply path for supplying fuel from the fuel tank 36 to the propulsion mechanism 33.

[0053] The speed governor 38 controls the rotational speed of the propulsion mechanism 33 by adjusting the amount of fuel injected into the propulsion mechanism 33 according to the instruction data output from the information processing device 1.

[0054] The flow meter 40 measures the flow rate of fuel moving within the fuel pipe 37 and outputs flow data representing the measured flow rate at predetermined time intervals. The tachometer 41 measures the rotational speed (rotational speed per unit time) of the propulsion mechanism 33 and outputs rotational speed data representing the measured rotational speed at predetermined time intervals.

[0055] The draft gauge 42 measures the draft of the vessel 3 and outputs draft data representing the measured draft at predetermined time intervals. The satellite navigation system 43 uses an antenna configured at a predetermined location on the vessel 3 to receive navigation signals transmitted from multiple navigation satellites, uses the received navigation signals to calculate the antenna's position (latitude and longitude), and outputs position data representing the calculated position at predetermined time intervals.

[0056] Information processing device 1 is a device that outputs the fuel consumption per unit load and per unit distance of ship 3. Figure 2 This is a block diagram showing the hardware structure of the information processing device 1. The hardware structure of the information processing device 1 is that of a general computer, including an arithmetic unit 11, a storage unit 12, an input / output (IF) unit 13, and a UI (User Interface) unit 14.

[0057] The storage unit 12 includes a storage device such as a hard disk drive for storing programs and data. The arithmetic unit 11 includes a processor and a memory used as a workspace for data processing, and performs various data processing tasks according to the programs stored in the storage unit 12.

[0058] The input / output IF unit 13 is connected to the speed controller 38, flow meter 40, tachometer 41, draft gauge 42, satellite navigation system 43, and touch display 2. The arithmetic unit 11 receives flow data from the flow meter 40 via the input / output IF unit 13, and the storage unit 12 stores the flow data corresponding to the receiving time (representing the measurement time). Similarly, the arithmetic unit 11 receives rotational speed data from the tachometer 41 via the input / output IF unit 13, and the storage unit 12 stores the rotational speed data corresponding to the receiving time (representing the measurement time). Furthermore, the arithmetic unit 11 receives draft data from the draft gauge 42 via the input / output IF unit 13, and the storage unit 12 stores the draft depth data corresponding to the receiving time (representing the measurement time). Finally, the arithmetic unit 11 receives position data from the satellite navigation system 43 via the input / output IF unit 13, and the storage unit 12 stores the position data corresponding to the receiving time (representing the measurement time).

[0059] The UI unit 14 may include a touch screen for displaying various information and accepting user input. Alternatively, the UI unit 14 may be configured as a separate device from the main body of the information processing unit 1, connected to the input / output IF unit 13. The arithmetic unit 11 generates instruction data representing the operation instruction to the speed controller 38 according to the user's operation, and sends the instruction data to the speed controller 38 via the input / output IF unit 13.

[0060] The user-received operations on the UI unit 14 or touch display 2 include inputting arrival and departure times related to the various ports along the route of the vessel 3. The data representing the arrival and departure times input by the user is stored in the storage unit 12. The storage unit 12, for example... Figure 3 The port arrival and departure tables shown in the diagram store data representing arrival and departure times entered by the user. The "Port Name" column of the port arrival and departure tables contains pre-stored names of ports along the route of vessel 3. The user selects the desired port from these names and then enters the arrival or departure time.

[0061] Figure 4 This is a block diagram showing the functional structure of the information processing device 1. Figure 4 The structure shown is implemented by the arithmetic unit 11 performing data processing according to the program stored in the storage unit 12.

[0062] The load data acquisition unit 21 acquires load data representing the load of the vessel 3, that is, the amount of cargo carried by the vessel 3. In this embodiment, the load data acquisition unit 21 reads draft depth data from the storage unit 12 and generates load data representing the amount obtained by subtracting the light-load displacement of the vessel 3 from the displacement corresponding to the draft depth represented by the read draft depth data, thereby acquiring the load data. Therefore, the load represented by the load data in this embodiment is a quantity generally referred to as cargo weight. The main details of cargo weight are the weight of cargo, the weight of ballast water, and the weight of fuel, but cargo weight also includes the weight of fresh water, bilge, and crew, etc.

[0063] The navigation distance data acquisition unit 22 acquires navigation distance data representing the navigation distance of the vessel 3. In this embodiment, the navigation distance data acquisition unit 22 reads position data from the storage unit 12 and generates navigation distance data representing the distance of the path obtained by connecting the positions represented by the read position data in a time sequence, thereby acquiring the navigation distance data.

[0064] The fuel consumption data acquisition unit 23 acquires fuel consumption data representing the fuel consumption of the ship 3. In this embodiment, the fuel consumption data acquisition unit 23 reads flow rate data from the storage unit 12 and generates fuel consumption data representing the cumulative flow rate of fuel represented by the read flow rate data, thereby acquiring the fuel consumption data.

[0065] The calculation unit 24 uses the load data obtained by the load data acquisition unit 21, the navigation distance data obtained by the navigation distance data acquisition unit 22, and the fuel consumption data obtained by the fuel consumption data acquisition unit 23 to calculate the fuel consumption per unit load per unit distance.

[0066] Output unit 25 outputs information related to the fuel consumption per unit load per unit distance calculated by calculation unit 24. In this embodiment, output unit 25 outputs data representing the fuel consumption per unit load per unit distance to storage unit 12 corresponding to the time of that point in time (representing the measurement time). Storage unit 12 stores the data output by output unit 25.

[0067] The display unit 26 causes the UI unit 14 and the touch display 2 to display a screen showing information related to fuel consumption per unit load per unit distance, output by the output unit 25. In this embodiment, the display unit 26 reads data representing fuel consumption per unit load per unit distance, output by the output unit 25 and stored in the storage unit 12, and causes the UI unit 14 and the touch display 2 to display a screen showing information, which includes the fuel consumption per unit load per unit distance represented by the read data (described later). Figure 5 ).

[0068] The operation unit 27 receives user commands. The instruction unit 28 provides the speed controller 38, which controls the rotational speed of the propulsion mechanism 33, with an action instruction corresponding to the command received by the operation unit 27.

[0069] Figure 5 This is a diagram showing the screen displayed on the UI unit 14 and the touch display 2. Furthermore, Figure 5 The "#" symbol represents a number. In this screen, as hypothetical controllers, there are controllers 51 displayed as "Speed ​​Setting", controller 52 displayed as "Fuel Consumption Setting", controller 53 displayed as "Port Arrival / Departure Time Input", and numeric keypad 54.

[0070] When the user operates the controller 51, the speed setting is accepted based on the numeric keypad 54. The arithmetic unit 11 sends instruction data to the speed controller 38 via the input / output IF unit 13. This instruction data represents an action instruction to operate the propulsion mechanism 33 at the speed set by the user. The speed controller 38 adjusts the fuel injection amount in the propulsion mechanism 33 according to the action instruction represented by the instruction data, so that the propulsion mechanism 33 operates at the speed set by the user.

[0071] When the user operates the controller 52, the fuel consumption (fuel consumption per unit time) setting is accepted based on the numeric keypad 54. The arithmetic unit 11 sends instruction data to the speed controller 38 via the input / output IF unit 13. This instruction data represents an operation instruction for operating the propulsion mechanism 33 at the set fuel consumption. The speed controller 38 adjusts the fuel injection amount in the propulsion mechanism 33 according to the operation instruction represented by the instruction data to achieve the fuel consumption set by the user.

[0072] In addition, Figure 5 In the video, the fuel consumption setting becomes invalid when the engine speed is set, and the engine speed setting becomes invalid when the fuel consumption is set.

[0073] When the user operates the controller 53, the numeric keypad 54 is first used to accept the selection of ports along the route for the vessel 3. Then, the user selects either the arrival or departure time for the selected port. Afterward, the user inputs either the arrival or departure time for the selected port.

[0074] In zone 55, the current rotational speed of the propulsion mechanism 33 is displayed as a measured value. Additionally, if the user has set the rotational speed, that user-set speed is also displayed in zone 55. The measured rotational speed displayed in zone 55 is, for example, the rotational speed represented by the latest rotational speed data stored in the storage unit 12.

[0075] In zone 56, the current fuel consumption (fuel consumption per unit time) of the propulsion mechanism 33 is displayed as a measured value. Additionally, if a user-set fuel consumption rate is used, this user-set rate is also displayed in zone 56. Figure 5 This example illustrates a scenario where the user sets the engine speed, but the set value for fuel consumption is not displayed in zone 56. The measured value of fuel consumption displayed in zone 56 is, for example, the cumulative value of flow rate represented by flow rate data stored in the storage unit 12 corresponding to the time period of the previous unit of time (e.g., converting flow rate per minute (liters) to flow rate per hour (tons)).

[0076] Area 57 displays the current load (cargo weight) of vessel 3 and the current fuel consumption per unit load per unit distance. Additionally, area 58 displays a curve showing the time-varying changes in the past fuel consumption per unit load per unit distance for vessel 3. Figure 6 This is a flowchart illustrating the processing performed by information processing device 1 to display information related to the load capacity of ship 3 and fuel consumption per unit load per unit distance in areas 57 and 58. The following explanation... Figure 6 The processing flow is shown.

[0077] Information processing device 1 determines whether a predetermined time (e.g., one minute) has elapsed (step A01). If the predetermined time has elapsed (step A01: "Yes"), load data acquisition unit 21 reads from storage unit 12 the draft data stored corresponding to the time within the previous predetermined time period (e.g., one minute) (step A02).

[0078] Next, the load data acquisition unit 21 determines a representative value (e.g., latest value, average value, median value, etc.) of the draft depth represented by the read draft depth data (step A03). Then, the load data acquisition unit 21 calculates the current load (cargo weight) of the vessel 3 by subtracting the light-load displacement of the vessel 3 from the displacement (current displacement of the vessel 3) corresponding to the representative draft depth determined in step A03 (step A04). Furthermore, the light-load displacement of the vessel 3 is, for example, a constant calculated by the manufacturer of the vessel 3, and this light-load displacement of the vessel 3 is preset in the information processing device 1.

[0079] The loading data acquisition unit 21 generates loading data representing the loading amount calculated in step A04, and the storage unit 12 stores the loading data in correspondence with, for example, the time of the measurement point (step A05).

[0080] In parallel with the processing in steps A02 to A05, the navigation distance data acquisition unit 22 reads from the storage unit 12 the position data stored corresponding to the time within the previous predetermined time period (e.g., one minute) (step A06). Next, the navigation distance data acquisition unit 22 calculates the distance of the path obtained by connecting the positions represented by the read position data in time sequence to a value representing the navigation distance of the ship 3 within the previous predetermined time period (step A07).

[0081] The navigation distance data acquisition unit 22 generates navigation distance data representing the navigation distance calculated in step A07, and the storage unit 12 stores the navigation distance data in correspondence with, for example, the time of that point in time (representing the measurement time) (step A08).

[0082] In parallel with the processing in steps A02 to A08, the fuel consumption data acquisition unit 23 reads the flow rate data stored in the storage unit 12 corresponding to the time within the previous specified time period (e.g., one minute) (step A09). Next, the fuel consumption data acquisition unit 23 calculates the cumulative value of the flow rate represented by the read flow rate data as a value representing the fuel consumption of the ship 3 during the previous specified time period (step A10).

[0083] The fuel consumption data acquisition unit 23 generates fuel consumption data representing the fuel consumption calculated in step A10, and the storage unit 12 stores the fuel consumption data in correspondence with, for example, the time of the measurement point (step A11).

[0084] When the processing of steps A02 to A11 is completed, the calculation unit 24 then calculates the fuel consumption per unit load per unit distance during the previous specified time period (e.g., 1 minute) by dividing the fuel consumption represented by the fuel consumption data generated in step A11 by multiplying the load represented by the load data generated in step A05 and the travel distance represented by the travel distance data generated in step A08 (step A12).

[0085] The calculation unit 24 generates data representing the fuel consumption per unit load per unit distance calculated in step A12. The data representing the fuel consumption per unit load per unit distance generated by the calculation unit 24 is output by the output unit 25 to the storage unit 12, for example, corresponding to the time of measurement (representing the measurement time). The storage unit 12 stores the data output from the output unit 25 (step A13).

[0086] When step A13 is completed, the information processing device 1 repeats the processing after step A01. As a result, the storage unit 12 stores data representing the time-series changes in load capacity, travel distance, fuel consumption, and fuel consumption per unit load per unit distance.

[0087] Showing Figure 5 The load capacity and fuel consumption per unit load per unit distance in area 57 of the screen shown are values ​​represented by the latest data stored in storage unit 12 as described above. Furthermore, the curve displayed in area 58 is generated using time-series data stored in storage unit 12 representing the fuel consumption per unit load per unit distance.

[0088] According to this embodiment, the user can understand the fuel consumption per unit load per unit distance of the vessel over a specified period in the past. As a result, the user can evaluate the vessel's fuel consumption by taking into account the amount of cargo and the transport distance.

[0089] [Variation Example]

[0090] The above-described embodiments can also be modified in various ways within the scope of the technical concept of the present invention. Examples of these modifications are shown below. Furthermore, these modifications can be appropriately combined.

[0091] (1) In the above embodiment, the load data acquisition unit 21 uses draft depth data to calculate the load and generates load data representing the calculated load. The method by which the load data acquisition unit 21 acquires the load data is not limited to this. For example, the user may input the load, and the load data acquisition unit 21 may acquire load data representing the load input by the user.

[0092] (2) In the above embodiment, the load data acquisition unit 21 acquires load data representing the cargo weight. The cargo weight includes the weight of ballast water and fuel in addition to the weight of the cargo. The load represented by the load data acquired by the load data acquisition unit 21 is not limited to a weight including the weight of the cargo, the weight of the ballast water, and the weight of the fuel. For example, the load data acquisition unit 21 may also acquire load data representing the weight of the cargo.

[0093] When the loading data acquisition unit 21 acquires loading data representing the weight of the cargo, in addition to acquiring draft depth data, the loading data acquisition unit 21 also acquires ballast water volume data representing the weight of ballast water loaded on the ship 3 and fuel volume data representing the weight of fuel loaded on the ship 3, and generates loading data representing the weight obtained by subtracting the weight of ballast water represented by ballast water volume data, the weight of fuel represented by fuel volume data, and the light load displacement of the ship 3 from the displacement corresponding to the draft depth represented by the draft depth data.

[0094] In this variation, for example, the ship 3 is equipped with a level gauge for measuring the level of fuel contained in the fuel tank 36 and a level gauge for measuring the level of ballast water contained in the ballast water tank 39. The information processing device 1 receives level data indicating the level of fuel or ballast water from each of these level gauges at predetermined intervals, and stores the level data in the storage unit 12 in correspondence with the time of receipt (indicating the measurement time).

[0095] Load data acquisition unit 21 in Figure 6 In step A02, in addition to reading the draft depth data, the liquid level data related to fuel and ballast water are also read. Furthermore, the load data acquisition unit 21... Figure 6 In step A03, in addition to determining the representative value of the draft depth, representative values ​​of the liquid levels related to fuel and ballast water are also determined, generating fuel quantity data and ballast water quantity data. The fuel quantity data represents the weight of fuel corresponding to the determined representative value of the fuel liquid level, and the ballast water quantity data represents the weight of ballast water corresponding to the determined representative value of the ballast water liquid level.

[0096] Load data acquisition unit 21 is used in Figure 6 The fuel quantity data and ballast water quantity data generated in step A03 as described above are used to generate the loading quantity data.

[0097] According to this variation, the fuel consumption for transporting a unit weight of goods a unit distance is indicated as the fuel consumption per unit load per unit distance. As a result, the user can evaluate fuel consumption from the perspective of cargo transport efficiency.

[0098] Furthermore, in this modified example, the method by which the load data acquisition unit 21 acquires load data representing the weight of the cargo is not limited to the method described above. For example, the load data acquisition unit 21 may use draft data representing the draft depth measured by the draft gauge 42 when the ship 3 has completed unloading all cargo at the port and draft data representing the draft depth measured by the draft gauge 42 when the cargo has been loaded, to generate load data representing the weight of the cargo. In this case, the load data acquisition unit 21 generates load data representing the value obtained by subtracting the displacement corresponding to the draft depth corresponding to the loading completion from the displacement corresponding to the draft depth corresponding to the unloading completion.

[0099] (3) In the above embodiment, the load data acquisition unit 21 acquires draft data representing the draft depth of the ship 3 at each of multiple time points during the ship 3's navigation, and generates load data for each of these multiple time points, representing the amount obtained by subtracting the light-load displacement of the ship 3 from the displacement corresponding to the draft depth represented by the draft data. Therefore, it displays the fuel consumption per unit load per unit distance, reflecting the changes in cargo weight that occur with the intake and discharge of ballast water and fuel consumption during the ship 3's navigation.

[0100] In cases where ballast water is not taken in or discharged during navigation, and the fuel consumption during navigation is so small as to be negligible compared to the cargo weight, the following structure may also be adopted: the load data acquisition unit 21 does not calculate the cargo weight during navigation, and the load data acquisition unit 21 uses the cargo weight calculated using the draft data representing the draft depth of the ship 3 when it is anchored in port as the cargo weight during navigation.

[0101] (4) Alternatively, the output unit 25 may output information related to fuel consumption per unit load per unit distance for each inter-port route navigated by the vessel 3. In this variation, the calculation unit 24 determines the duration of the vessel 3's voyage on each inter-port route based on the arrival and departure times associated with each port along the vessel 3's route, input by the user. Then, the calculation unit 24 uses the load data, voyage distance data, and fuel consumption data corresponding to the determined duration to calculate the fuel consumption per unit load per unit distance. The output unit 25 outputs data representing the fuel consumption per unit load per unit distance for each inter-port route calculated by the calculation unit 24.

[0102] According to this variation, the user can evaluate the fuel consumption of vessel 3 for each inter-port route in the inter-port route.

[0103] (5) Alternatively, the output unit 25 may output information related to fuel consumption per unit load per unit distance for the navigation of the vessel 3 during a specified past period (e.g., a year in a calendar year). In this variation, the calculation unit 24 uses load data, navigation distance data, and fuel consumption data corresponding to the period from the start time (e.g., 00:00 on January 1st of the target year) to the end time (e.g., 24:00 on December 31st of the target year) of the specified past period to calculate the fuel consumption per unit load per unit distance. The output unit 25 outputs data representing the fuel consumption per unit load per unit distance during navigation during the specified past period calculated by the calculation unit 24.

[0104] According to this variation, the user can evaluate the fuel consumption of ship 3 over a specified period in the past.

[0105] (6) Alternatively, the fuel consumption data acquisition unit 23 acquires fuel consumption data representing the fuel consumption of the ship 3 related to each of the multiple fuels, and the output unit 25 outputs information related to the fuel consumption per unit load per unit distance for each of these multiple fuels.

[0106] This modification applies to situations where the propulsion mechanism 33 can switch between multiple fuels (e.g., heavy fuel oil A, heavy fuel oil C, and natural gas). In this modification, the vessel 3 is equipped with, for example, a flow meter that measures the flow rate of fuel flowing from a fuel tank containing a first type of fuel (e.g., heavy fuel oil A) to the propulsion mechanism 33, and a flow meter that measures the flow rate of fuel flowing from a fuel tank containing a second type of fuel (e.g., heavy fuel oil C) to the propulsion mechanism 33. The fuel consumption data acquisition unit 23 uses the flow rate data representing the flow rate measured by each of these flow meters to generate fuel consumption data representing the fuel consumption of the vessel 3 related to each of the multiple fuels.

[0107] The calculation unit 24 calculates the fuel consumption per unit load per unit distance for each of the multiple fuels, and the output unit 25 outputs data representing the fuel consumption per unit load per unit distance calculated by the calculation unit 24 for each of the multiple fuels.

[0108] According to this variation, the user can evaluate the fuel consumption of the ship 3 when using each type of fuel.

[0109] (7) Alternatively, the information processing device 1 may include a location data acquisition unit that acquires location data representing the position of the vessel 3, and an output unit 25 that outputs information related to fuel consumption per unit load per unit distance for each of the multiple sea areas in which the vessel 3 has sailed, determined based on the position data. Furthermore, the location data acquisition unit may acquire, for example, location data output from a satellite navigation system 43.

[0110] In this modified example, the calculation unit 24 determines the duration of the vessel 3's voyage in each of the multiple sea areas based on the location data stored in the storage unit 12. Then, for each of the multiple sea areas, the calculation unit 24 calculates the fuel consumption per unit load per unit distance using the determined period's load data, voyage distance data, and fuel consumption data. The output unit 25 outputs data representing the fuel consumption per unit load per unit distance calculated by the calculation unit 24 for each of the multiple sea areas.

[0111] According to this variation, the user can evaluate the fuel consumption of ship 3 when navigating in each of the different sea areas.

[0112] (8) Alternatively, the output unit 25 may output information containing carbon dioxide emissions per unit load per unit distance, which is calculated using fuel consumption per unit load per unit distance calculated by the calculation unit 24.

[0113] In this variation, the calculation unit 24 calculates the carbon dioxide emissions per unit load per unit distance by multiplying the calculated fuel consumption per unit load per unit distance by a carbon dioxide conversion factor corresponding to the fuel type (a factor representing the weight of carbon dioxide emitted when a unit weight of fuel is burned). The output unit 25 outputs data representing the carbon dioxide emissions per unit load per unit distance calculated by the calculation unit 24.

[0114] According to this variation, the user can evaluate the fuel consumption of ship 3 from the perspective of carbon dioxide emissions.

[0115] (9) The information processing device 1 may also include a notification unit that notifies an alarm when the information related to fuel consumption per unit load per unit distance output by the output unit 25 meets predetermined conditions. In this variation, when predetermined conditions are met, such as the fuel consumption per unit load per unit distance represented by the data output by the output unit 25 exceeding a predetermined threshold, the notification unit notifies an alarm using a display, sound, or the like.

[0116] According to this variation, when the efficiency of the fuel consumption of ship 3 deteriorates, taking into account the amount of cargo and the transport distance, the user can easily detect the situation.

[0117] (10) In the above-described embodiments or variations thereof, at least some of the measuring devices (flow meter 40, draft gauge 42, satellite navigation system 43, fuel or ballast water level gauge, etc.) provided by the ship 3 may be replaced with other types of measuring devices. For example, a level gauge that measures the level of fuel contained in the fuel tank 36 may be used instead of the flow meter 40. In this case, the fuel consumption data acquisition unit 23 uses the reduction in the remaining amount of fuel represented by the level data output from the level gauge instead of the fuel consumption represented by the flow data output from the flow meter 40 to calculate the fuel consumption.

[0118] Alternatively, at least some of the measurements performed by the measuring equipment (flow meter 40, draft gauge 42, satellite navigation system 43, fuel or ballast water level gauge, etc.) on the vessel 3 can be replaced by visual measurements by the crew. For example, when the vessel 3 is anchored in port, the crew visually measures the draft using a draft gauge marked on the hull 30. Furthermore, the crew operates the UI unit 14 or the touch display 2 to input the measured draft into the information processing device 1. The load data acquisition unit 21 uses draft data representing the draft input by the crew instead of the draft data output from the draft gauge 42.

[0119] (11) The unit of loading capacity can also be any of metric tons, British tons, US tons, etc. In addition, in the above embodiment, the loading capacity is set as weight, but the loading capacity can also be a quantity other than weight. For example, if the loading capacity represents the quantity of goods and the density of the goods is uniform, the volume of the goods can also be used instead of the weight of the goods as the loading capacity.

[0120] (12) In the above embodiment, the fuel consumption of the ship 3 is set as the fuel consumption of the propulsion mechanism 33. However, the fuel consumption of the ship 3 may also include the fuel consumption of devices other than the propulsion mechanism 33. For example, if the ship 3 is equipped with an engine for generating electricity in addition to the propulsion mechanism 33, the total value of the fuel consumption of the engine and the fuel consumption of the propulsion mechanism 33 may be used as the fuel consumption of the ship 3.

[0121] (13) The configuration of the information processing device 1 is not limited to the bridge 31. In addition, the configuration of the touch display 2 is not limited to the mechanism control room 32. Alternatively, a device with the same structure as the information processing device 1 may be used instead of the touch display 2.

[0122] (14) In the above-described embodiments, the information processing device 1 is implemented by a computer performing data processing according to a program. Alternatively, the information processing device 1 may also be configured as a so-called dedicated device.

[0123] (15) The program for causing the computer to perform the processing performed by the information processing device 1 may be provided, for example, either stored in a computer-readable recording medium such as an optical recording medium or a semiconductor memory, or provided via a communication network such as the Internet. When the program according to the present invention is provided stored in a recording medium, the computer reads the program from the recording medium for use. Alternatively, when the program according to the present invention is provided via a communication network, the computer receives the program from the device of the publishing source for use.
