DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a cargo handling planning device, a cargo handling planning method, and a program according to an embodiment of the present disclosure will be described with reference to FIGS. The cargo handling planning device 10 of this embodiment is used to plan cargo handling of a ship 1 that transports a vehicle 100. Examples of ship types for the ship 1 that transports the vehicle 100 include a ferry, a RORO ship (roll-on / roll-off ship), and a PCTC (pure car & truck carrier).

[0011] As shown in FIG. 1 , the vessel 1 includes a deck 3 within its hull 2 ​​that can accommodate multiple vehicles 100. The deck 3 is provided with multiple parking bays 5 for parking the multiple vehicles 100. The deck 3 illustrated in this embodiment has five parking bay rows 5L arranged in the width direction Dw of the hull 2. Each parking bay row 5L has, for example, ten parking bays 5 arranged in series in the fore-aft direction FA. Each parking bay 5 has a rectangular shape in plan view, with the fore-aft direction FA as its longitudinal direction. The vehicles 100 to be loaded are parked in the parking bays 5, which have a rectangular shape in plan view, with the fore-aft direction FA as their longitudinal direction, with the fore-aft direction of the vehicle 100 aligned with the fore-aft direction FA. The layout of the multiple parking bays 5 on the deck 3 is not limited to that shown above and can be modified as appropriate.

[0012] (Cargo handling planning device) FIG. 2 is a diagram illustrating a hardware configuration of the cargo handling planning device according to the embodiment of the present disclosure. The cargo handling planning device 10 (see FIG. 2) creates a layout plan for the vehicles 100 when loading the vehicles 100 into the multiple parking bays 5 set up on the deck 3. The cargo handling planning device 10 determines the lashing conditions for lashing each vehicle 100 with a lashing belt for each of the multiple parking bays 5. A worker supervising the loading of the vehicles 100 onto the ship 1 instructs the loading positions of the multiple vehicles 100 on the deck 3 based on the layout plan for the vehicles 100 created by the cargo handling planning device 10. The instructed worker then lashes the vehicles 100 with a lashing belt in each of the multiple parking bays 5 based on the lashing conditions determined by the cargo handling planning device 10.

[0013] (Hardware configuration diagram) As shown in FIG. 2, the cargo handling planning device 10 is a computer including a CPU 11 (Central Processing Unit), a ROM 12 (Read Only Memory), a RAM 13 (Random Access Memory), a storage 14 such as an HDD (Hard Disk Drive), and an input / output module 15.

[0014] (Function block diagram) FIG. 3 is a functional block diagram of the cargo handling planning device according to the embodiment of the present disclosure. As shown in Figure 3, the CPU 11 of the cargo handling planning device 10 executes a program stored in advance in storage 14 such as an HDD, thereby realizing the functional configurations of an input unit 21, a ship information memory unit 22, a ship motion basic information acquisition unit 23, an operating condition acquisition unit 24, a vehicle information memory unit 25, a ship motion acquisition unit 26, a tipping moment acquisition unit 27, a vehicle placement planning unit 28, an external force calculation unit 29, a securing condition calculation unit 30, and an output unit 31.

[0015] The input unit 21 receives information required for a cargo handling plan input by an operator. The input unit 21 in this embodiment receives information input from the outside via the input / output module 15, which is hardware. An input device (not shown) is connected to the input / output module 15 in this embodiment. Examples of the input device include a keyboard, a mouse, a tablet terminal, a smartphone, etc., which can be connected to the input / output module 15 of the cargo handling planning apparatus 10 by wire or wirelessly.

[0016] The ship information storage unit 22 stores information about the ship 1 that is necessary to create a cargo handling plan for the ship 1. The information about the ship 1 includes the length of the ship 1 in the bow-stern direction FA, the ship's width, draft depth, center of gravity, weight, etc. The information about the ship 1 also includes map information showing the positions of multiple parking spaces 5 on the deck 3, etc.

[0017] The ship motion basic information acquisition unit 23 acquires the ship motion basic information before creating a cargo handling plan for the ship 1. Here, the ship motion basic information is information about the ship motion of the ship 1 that may occur under various conditions while the ship 1 is operating.

[0018] FIG. 4 is a diagram illustrating hull motion of a ship according to an embodiment of the present disclosure. As shown in Figure 4, basic hull motion information for ship 1 includes, for example, the maximum inclination angle and acceleration in rolling motion around axis S1, the maximum inclination angle and acceleration in pitching motion around axis S2, and acceleration due to vertical motion.

[0019] The ship motion basic information acquisition unit 23 calculates the ship motion basic information based on a plurality of conditions assumed during operation of the ship 1, for example, input by an operator. Examples of the plurality of conditions assumed during operation of the ship 1 include a plurality of stages of ship speed assumed during operation of the ship 1. Examples of other conditions among the plurality of conditions include a plurality of stages of draft and stability of the ship 1, which vary depending on the amount of cargo carried. Examples of still other conditions include, for example, wave conditions assumed in the sea area in which the ship will operate, specifically, a plurality of combinations of wave height, wave period, and wave direction assumed in the sea area in which the ship will operate. The ship motion basic information acquired by the ship motion basic information acquisition unit 23 is information about the ship motion without taking into account the cargo weight.

[0020] The hull motion basic information acquisition unit 23 calculates information about hull motion that may occur to the ship 1 during operation based on the length in the bow-stern direction FA of the ship 1, the ship's width, draft depth, center of gravity, etc., stored in the ship information storage unit 22. The hull motion basic information acquisition unit 23 calculates information about hull motion that may occur to the ship 1 during operation as hull motion basic information by combining multiple conditions that are expected when the ship 1 is operating as described above. The hull motion basic information acquisition unit 23 stores the calculated information about hull motion, for example, as table information. The acquisition of information on the hull motion of the ship 1 by the hull motion basic information acquisition unit 23 may be performed every time the ship 1 departs, or may be performed only once in advance.

[0021] When creating a cargo handling plan for the ship 1, the navigation condition acquisition unit 24 externally acquires the navigation conditions expected on the route when the ship 1 is operating. The navigation conditions include the ship speed on the route based on the navigation plan for the ship 1. Further, other navigation conditions include wave conditions such as wave height, wave period, and wave direction expected while the ship 1 is operating.

[0022] The vehicle information storage unit 25 stores information about the multiple vehicles 100 mounted on the vessel 1. Specifically, examples of the information about the vehicles 100 include the type of vehicle 100 (trailer, truck, general vehicle, etc.), the weight of the vehicle 100, the length of the vehicle 100, etc.

[0023] When creating a cargo handling plan for the ship 1, the hull motion acquisition unit 26 acquires information about the hull motion of the ship 1 that is expected on the route when the ship 1 is operating. Examples of hull motion of the ship 1 include the inclination angle and acceleration around axis S1, and the inclination angle and acceleration around axis S2. The hull motion acquisition unit 26 acquires the maximum inclination angle and acceleration around axis S1 and axis S2 when the ship 1 rolls, based on the operating conditions of the ship 1 and the total weight of multiple vehicles 100 carried on the ship 1. The information about hull motion acquired by this hull motion acquisition unit 26 is information about hull motion assuming a state in which cargo, i.e., vehicles 100, are loaded.

[0024] When acquiring information about the hull motion of the ship 1, the hull motion acquisition unit 26 acquires the operating conditions of the ship 1 from the operating condition acquisition unit 24. The hull motion acquisition unit 26 calculates the total weight of the multiple vehicles 100 based on the weights of the multiple vehicles 100 stored in the vehicle information storage unit 25. The hull motion acquisition unit 26 acquires the maximum inclination angle and acceleration around the axis S1 and the axis S2 that occur in the ship 1, assuming that the total weight of the multiple vehicles 100 acts evenly on the multiple parking spaces 5 set on the deck 3.

[0025] At this time, the hull motion acquisition unit 26 can acquire the maximum inclination angle and acceleration around the axis S1 and the axis S2 that occur in the ship 1 based on the information about the hull motion of the ship 1 acquired by the hull motion basic information acquisition unit 23. Specifically, for example, by referring to table information created based on the information about the hull motion of the ship 1 acquired by the hull motion basic information acquisition unit 23, information about the hull motion of the ship 1 under conditions where the operating conditions of the ship 1 (for example, sea conditions such as wave height, wave period, and wave direction on the day of operation) and the draft determined according to the total weight of the multiple vehicles 100 loaded on the ship 1 match is acquired.

[0026] The overturning moment acquisition unit 27 acquires, for each parking space 5, the external force and overturning moment acting on the vehicle 100 loaded in the parking space 5, based on the information about the hull motion of the vessel 1 acquired by the hull motion acquisition unit 26. Specifically, the overturning moment acquisition unit 27 calculates the moment that occurs in each parking space 5 when the vessel 1 is tilted at the maximum tilt angle acquired by the hull motion acquisition unit 26. Then, when the vessel 1 is rocking at the maximum acceleration acquired by the hull motion acquisition unit 26, the overturning moment acquisition unit 27 calculates the external force acting on the vehicle 100 based on the acceleration acting on each parking space 5. At this time, the overturning moment due to acceleration generated when the vessel 1 sways around the axis S2 increases at positions distant in the vessel's width direction Dw and in the fore-and-aft direction FA. In particular, the overturning moment acting on the parking spaces 5 near the sides 4A, 4B on both sides of the vessel's width direction Dw near the bow and stern 2b in the fore-and-aft direction FA increases.

[0027] The vehicle layout planning unit 28 plans the layout of the plurality of vehicles 100 relative to the plurality of parking spaces 5 based on the magnitude of the external force and the overturning moment for each parking space 5 acquired by the overturning moment acquisition unit 27 .

[0028] FIG. 5 is a diagram illustrating an example of a plurality of parking spaces divided into levels by the cargo handling planning device according to the embodiment of the present disclosure. Here, the vehicle layout planning unit 28 classifies the magnitude of the external force and overturning moment for each of the multiple parking spaces 5 into multiple levels. Specifically, as shown in FIG. 5 , the magnitude of the external force and overturning moment is classified into, for example, five levels L1 to L5. The vehicle layout planning unit 28 identifies which of the levels L1 to L5 the external force and overturning moment for each parking space 5 falls into. The vehicle layout planning unit 28 plans the layout of the multiple vehicles 100 based on the classified levels of the external force and overturning moment. For example, the vehicle layout planning unit 28 may color-code each of the multiple parking spaces 5 on the deck 3 according to the levels L1 to L5 of the external force and overturning moment, and display the color on an external monitor device from the output unit 31 (described later). The vehicle layout planning unit 28 assigns parking positions for the multiple vehicles 100 to the multiple parking spaces 5 classified into levels based on the magnitude of the external force and overturning moment.

[0029] The external force calculation unit 29 individually calculates the external force acting on each of the multiple vehicles 100 based on the arrangement of the multiple vehicles 100 in the multiple parking spaces 5 planned by the vehicle arrangement planning unit 28. Specifically, for each parking space 5, the overturning moment acquisition unit 27 acquires the overturning moment and acceleration that occur when the vessel 1 tilts to the maximum tilt angle. The external force calculation unit 29 calculates the external force acting on each vehicle 100 when each vehicle 100 assigned by the vehicle arrangement planning unit 28 is parked in each parking space 5. In this case, even if the parking space 5 is the same, if the weight of the vehicle 100 is large, the external force acting on the vehicle 100 due to the overturning moment and acceleration acting on the parking space 5 will be large.

[0030] The lashing condition calculation unit 30 calculates the lashing conditions for lashing multiple vehicles 100 to the deck 3 with lashing belts based on the external forces calculated by the external force calculation unit 29. Specifically, the lashing condition calculation unit 30 calculates, based on the calculated external forces, the number of lashing belts required to lash each vehicle 100 parked in each parking space 5 to the deck 3, the tension when lashing the vehicle 100 with each lashing belt, etc.

[0031] The output unit 31 outputs information related to the cargo handling plan created by the cargo handling planning device 10 to the outside. In terms of hardware, the output unit 31 is an information output device connected via the input / output module 15. As the output unit 31, for example, a display monitor, a printer, a tablet terminal, a smartphone, or the like that can be connected to the input / output module 15 of the cargo handling planning device 10 by wire or wirelessly can be used.

[0032] The output unit 31 outputs to the outside, as information related to the loading and unloading plan, for example, information indicating a layout plan of the multiple vehicles 100 in the multiple parking spaces 5, which is acquired by the vehicle layout planning unit 28. The output unit 31 outputs to the outside, as information such as a map or table indicating the allocation positions of the multiple vehicles 100 to the multiple parking spaces 5, as the layout plan of the multiple vehicles 100.

[0033] Furthermore, the output unit 31 outputs to the outside, as information relating to the loading and unloading plan, for example, the securing conditions of each vehicle 100 parked in each parking space 5 calculated by the securing condition calculation unit 30. These securing conditions may also be shown, for example, on a map or table showing the allocation positions of the multiple vehicles 100 to the multiple parking spaces 5.

[0034] (Procedure for cargo handling planning method) FIG. 6 is a flowchart showing the procedure of the cargo handling planning method according to the embodiment of the present disclosure. As shown in Figure 6, the cargo handling planning method S10 of this embodiment includes step S11 of preparing information, step S12 of acquiring the hull motion of the ship 1, step S13 of acquiring the overturning moment, step S14 of planning the positioning of the vehicle 100, step S15 of calculating the securing conditions, and step S16 of outputting information. Prior to the cargo handling planning method S10 according to this embodiment, the ship motion basic information acquisition unit 23 acquires basic ship motion information regarding the ship motion of the ship 1 that may occur under various conditions during operation.

[0035] In step S11 of preparing information, the navigation condition acquisition unit 24 acquires from an external source the navigation conditions expected on the route when the ship 1 is operating. The acquired navigation conditions include, for example, the ship speed based on the navigation plan of the ship 1 and expected wave conditions. The navigation conditions may be input by the operator using the input unit 21, and the wave conditions in particular may be acquired from an external source via the Internet or the like.

[0036] Furthermore, in step S11 of preparing information, information about the multiple vehicles 100 to be loaded on the ship 1 is acquired. The information about the multiple vehicles 100 may be input by an operator using the input unit 21, or information about each vehicle 100 that has been registered in advance when the ship 1 is operated may be acquired from an external computer or the like. The vehicle information storage unit 25 stores the information about the multiple vehicles 100 to be loaded on the ship 1 that is acquired in step S11 of preparing information.

[0037] In step S12 of acquiring the hull motion of the ship 1, information is acquired about the hull motion of the ship 1 expected on the course during operation of the ship 1. The hull motion of the ship 1 to be acquired includes the maximum inclination angle and acceleration around the axis S1 and axis S2 that occur on the ship 1. The hull motion acquisition unit 26 acquires the maximum inclination angle and acceleration around the axis S1 and axis S2 that occur on the ship 1, assuming that the total weight of the multiple vehicles 100 acts evenly on the multiple parking spaces 5 set on the deck 3.

[0038] In step S13 of acquiring the overturning moment, the external force and overturning moment acting on the vehicle 100 loaded in each parking space 5 are acquired for each parking space 5. The overturning moment acquisition unit 27 calculates the external force and overturning moment that will occur in each parking space 5 when the vessel 1 tilts at the maximum tilt angle and acceleration acquired by the hull motion acquisition unit 26.

[0039] In step S14 of planning the placement of vehicles 100, the placement of the plurality of vehicles 100 relative to the plurality of parking spaces 5 is planned. Vehicle placement planning unit 28 plans the placement of vehicles 100 based on the magnitude of the external force and overturning moment for each parking space 5 acquired by overturning moment acquisition unit 27. At this time, the magnitude of the external force and overturning moment for each parking space 5 is classified into a plurality of levels, for example, L1 to L5. Then, parking positions of the plurality of vehicles 100 are assigned to the plurality of parking spaces 5 classified into levels based on the magnitude of the external force and overturning moment.

[0040] The allocation of the vehicles 100 to the parking sections 5 may be performed by, for example, an operator. In this case, the vehicle allocation planning unit 28 acquires the allocation positions of the vehicles 100 to the parking sections 5, which are externally input by the operator via the input unit 21, as an allocation plan for the vehicles 100 in the parking sections 5. The vehicle allocation planning unit 28 may also automatically allocate the vehicles 100 to the parking sections 5 based on a predetermined algorithm. For example, the vehicle allocation planning unit 28 may allocate a heavier vehicle 100 to a parking section 5 at level L1, for example, where the external force and overturning moment are low, based on the information of each vehicle 100 stored in the vehicle information storage unit 25. The vehicle allocation planning unit 28 may also sequentially allocate the vehicles 100 to parking sections 5 at level L1 to level L5 in descending order of weight based on the information of each vehicle 100 stored in the vehicle information storage unit 25.

[0041] In step S15 of calculating the lashing conditions, the lashing conditions are calculated for each vehicle 100 assigned to each parking space 5. At this time, the external force calculation unit 29 described above calculates the external forces acting on each of the multiple vehicles 100 based on the arrangement of the multiple vehicles 100 relative to the multiple parking spaces 5. The external force calculation unit 29 calculates the external forces acting on each vehicle 100 assigned to each parking space 5 when the maximum tilt angle and acceleration due to swinging about axis S1 and axis S2 are acting on the vehicle 100. Furthermore, based on the external forces calculated by the external force calculation unit 29, the lashing condition calculation unit 30 calculates the lashing conditions for lashing the multiple vehicles 100 to the deck 3 with lashing belts. Specifically, based on the external forces calculated by the external force calculation unit 29, the lashing condition calculation unit 30 calculates the number of lashing belts required to lash each vehicle 100 parked in each parking space 5 to the deck 3, the tension when lashing the vehicle 100 with each lashing belt, etc.

[0042] In step S16 of outputting information, the output unit 31 outputs to the outside information related to the cargo handling plan created by the cargo handling planning device 10. The output unit 31 outputs to the outside, as information related to the cargo handling plan, for example, information indicating a layout plan of multiple vehicles 100 in multiple parking spaces 5, acquired by the vehicle layout planning unit 28. The output unit 31 also outputs to the outside, as information related to the cargo handling plan, for example, the securing conditions of each vehicle 100 parked in each parking space 5, calculated by the securing condition calculation unit 30.

[0043] Based on the information related to the loading and unloading plan output in step S16, the workers on deck 3 park the vehicles 100 in the parking bays 5. Furthermore, the workers secure the vehicles 100 in each parking bay 5 based on the securing conditions output in step S16.

[0044] (Action and effect) In the cargo handling planning device 10 and cargo handling planning method S10 of the above embodiment, the hull motion of the ship 1 is acquired based on the operating conditions of the ship 1 and the total weight of the multiple vehicles 100 loaded on the ship 1. This makes it possible to predict with higher accuracy the hull motion of the ship 1 expected during operation of the ship 1 based on the operating conditions at that time and the total weight of the loaded vehicles 100. By acquiring the external force and overturning moment acting on the vehicle 100 for each of the multiple parking spaces 5 based on the hull motion of the ship 1 acquired in this way, it is possible to appropriately obtain the conditions necessary for lashing down the vehicle 100. This prevents the vehicle 100 from being excessively lashed down, making it possible to easily and appropriately lash down the vehicle 100.

[0045] Furthermore, in the above embodiment, the vehicle layout planning unit 28 plans the layout of the multiple vehicles 100 in the multiple parking spaces 5 based on the magnitude of the external force and the overturning moment for each of the multiple parking spaces 5. This makes it possible to appropriately layout the multiple vehicles 100 in the multiple parking spaces 5.

[0046] Furthermore, in the above embodiment, the vehicle layout planning unit 28 classifies the magnitude of the external force and overturning moment for each of the plurality of parking spaces 5 into a plurality of levels, and plans the layout of the plurality of vehicles 100 based on the classified levels of the external force and overturning moment. This makes it possible to easily recognize the magnitude of the external force and overturning moment for each parking space 5. Therefore, it is possible to easily plan the layout of the plurality of vehicles 100 for the plurality of parking spaces 5 based on the classified levels of the external force and overturning moment.

[0047] Furthermore, in the above embodiment, the vehicle layout planning unit 28 assigns heavier vehicles 100 out of the multiple vehicles 100 to parking spaces 5 where the external force and overturning moment are small. This reduces the external force and overturning moment acting on the heavier vehicles 100, effectively preventing the vehicles 100 from overturning. Furthermore, the need to securely fasten the heavier vehicles 100 is reduced, making the fastening work easier.

[0048] Furthermore, in the above embodiment, the external forces acting on each of the multiple vehicles 100 are calculated based on the arrangement of the multiple vehicles 100 relative to the multiple parking spaces 5, so that the securing conditions can be calculated with high accuracy for each of the multiple vehicles 100. Therefore, the vehicles 100 can be secured efficiently and reliably.

[0049] In the above embodiment, a program for realizing the various functions of the cargo handling planning device 10 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed to perform various processes. Here, the various processing steps of the CPU of the computer system are stored in the form of a program on a computer-readable recording medium, and the computer reads and executes the program to perform the various processes. The computer-readable recording medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc. Alternatively, the computer program may be distributed to a computer via a communication line, and the computer that receives the program may execute the program.

[0050] (Other embodiments) The above describes in detail the embodiments of the present disclosure with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes and the like are also included within the scope that does not deviate from the gist of the present disclosure. In the above embodiment, the vehicle 100 is parked in each parking space 5 with the fore-and-aft direction of the vehicle 100 aligned with the fore-and-aft direction FA, but this is not limited to this. For example, when the cargo utilization rate (loading rate) during operation is low, the vehicle 100 may be parked with the fore-and-aft direction of the vehicle 100 aligned along the deck 3 at an angle to the fore-and-aft direction FA, as shown in Fig. 7. In this case, when calculating the external forces and overturning moments acting on each of the multiple vehicles 100 arranged in the multiple parking spaces 5, the vehicle layout planning unit 28 may calculate the parking angle of the vehicle 100 in a diagonal direction relative to the fore-aft direction FA at multiple different angles. Parking the vehicle 100 at a diagonal direction relative to the fore-aft direction FA may improve stability when the vessel 1 rolls around the axis S1 compared to parking the vehicle 100 with its fore-aft direction aligned with the fore-aft direction FA. For example, the vehicle 100 may be parked at a diagonal parking angle of 90° relative to the fore-aft direction FA, i.e., the fore-aft direction of the vehicle 100 may be aligned with the vessel's width direction Dw. Parking the vehicle 100 at a diagonal direction relative to the fore-aft direction FA improves stability when the vessel 1 rolls around the axis S1, allowing the number and tension of lashing belts used for lashing the vessel 1 to be reduced.

[0051] <Additional Notes> The cargo handling planning device 10, the cargo handling planning method S10, and the program described in the embodiment can be understood, for example, as follows.

[0052] (1) The cargo handling planning device 10 according to the first aspect includes a hull motion acquisition unit 26 that acquires the hull motion of the ship 1 based on the operating conditions of the ship 1 and the total weight of a plurality of vehicles loaded in a plurality of parking spaces 5 set on the deck 3 inside the ship 1, assuming that the total weight acts on the plurality of parking spaces 5 evenly, and an overturning moment acquisition unit 27 that acquires the overturning moment acting on the vehicles loaded in each of the plurality of parking spaces 5 based on the hull motion.

[0053] This cargo handling planning device 10 acquires the hull motion of the ship 1 based on the operating conditions of the ship 1 and the total weight of multiple vehicles loaded on the ship 1. As a result, the hull motion of the ship 1 expected during operation of the ship 1 can be predicted with higher accuracy based on the operating conditions at that time and the total weight of the vehicles loaded on the ship 1. By acquiring the overturning moment acting on the vehicle for each of the multiple parking spaces 5 based on the hull motion of the ship 1 acquired in this way, the conditions necessary for lashing down the vehicles can be appropriately obtained. As a result, excessive lashing down of vehicles can be prevented, and vehicles can be easily and appropriately lashed down.

[0054] (2) The cargo handling planning device 10 according to the second aspect is the cargo handling planning device 10 of (1), further including a vehicle placement planning unit 28 that plans the placement of multiple vehicles relative to multiple parking spaces 5 based on the magnitude of the tipping moment for each parking space 5 acquired by the tipping moment acquisition unit 27.

[0055] This allows the placement of multiple vehicles in multiple parking spaces 5 to be planned based on the magnitude of the overturning moment for each of the multiple parking spaces 5, making it possible to appropriately place multiple vehicles in multiple parking spaces 5.

[0056] (3) The cargo handling planning device 10 according to the third aspect is the cargo handling planning device 10 of (2), in which the vehicle placement planning unit 28 divides the magnitude of the tipping moment for each parking space 5 into multiple levels and plans the placement of the multiple vehicles based on the divided tipping moment levels.

[0057] This allows the magnitude of the overturning moment for each of the plurality of parking spaces 5 to be divided into a plurality of levels, making it easy to recognize the magnitude of the overturning moment for each of the plurality of parking spaces 5. This makes it easy to plan the placement of a plurality of vehicles for the plurality of parking spaces 5 based on the divided overturning moment levels.

[0058] (4) The cargo handling planning device 10 according to the fourth aspect is the cargo handling planning device 10 of (2) or (3), and the vehicle placement planning unit 28 assigns the vehicle with the heaviest weight among the plurality of vehicles to the parking space 5 with the smallest tipping moment.

[0059] As a result, by allocating heavier vehicles among multiple vehicles to parking spaces 5 with a smaller tipping moment, the tipping moment acting on the heavier vehicles can be reduced, effectively preventing the vehicles from tipping over. This also reduces the need to securely fasten heavier vehicles, making the lashing work easier.

[0060] (5) The cargo handling planning device 10 according to the fifth aspect is any one of the cargo handling planning devices 10 according to (2) to (4), and further includes an external force calculation unit 29 that calculates the external forces acting on each of the plurality of vehicles based on the arrangement of the plurality of vehicles relative to the plurality of parking spaces 5 planned by the vehicle arrangement planning unit 28, and a securing condition calculation unit 30 that calculates securing conditions for securing the plurality of vehicles to the deck 3 with securing belts based on the external forces calculated by the external force calculation unit 29.

[0061] This makes it possible to calculate the securing conditions for each of the multiple vehicles with high accuracy by calculating the external forces acting on each of the multiple vehicles based on the arrangement of the multiple vehicles relative to the multiple parking spaces 5. Therefore, the vehicles can be secured efficiently and reliably. The securing conditions include the number of securing belts used to secure the vehicle to the deck 3, the tension applied to the securing belts, etc.

[0062] (6) The cargo handling planning method S10 according to the sixth aspect includes a step S11 of acquiring the hull movement of the ship 1 based on the operating conditions of the ship 1 and the total weight of a plurality of vehicles loaded in a plurality of parking spaces 5 set on the deck 3 inside the ship 1, assuming that the total weight acts on the plurality of parking spaces 5 evenly; and a step S12 of acquiring the overturning moment acting on the vehicles loaded in each of the plurality of parking spaces 5 based on the hull movement.

[0063] This makes it possible to obtain the conditions necessary for securing the vehicle appropriately by obtaining the overturning moment acting on the vehicle for each of the multiple parking spaces 5 based on the obtained hull motion of the vessel 1. This prevents excessive vehicle lashing and makes it possible to secure the vehicle easily and appropriately.

[0064] (7) The program relating to the seventh aspect causes a computer to execute the steps of: step S11 of acquiring the hull movement of the ship 1 based on the operating conditions of the ship 1 and the total weight of multiple vehicles loaded in multiple parking spaces 5 set on the deck 3 within the ship 1, assuming that the total weight acts on the multiple parking spaces 5 evenly; and step S12 of acquiring the overturning moment acting on the vehicles loaded in each of the multiple parking spaces 5 based on the hull movement.

[0065] This makes it possible to obtain the conditions necessary for securing the vehicle appropriately by obtaining the overturning moment acting on the vehicle for each of the multiple parking spaces 5 based on the obtained hull motion of the vessel 1. This prevents excessive vehicle lashing and makes it possible to secure the vehicle easily and appropriately. [Explanation of symbols]
