[0026] As Figure 1 shown in the drawings, the hull 2 of the ship 1 of the present embodiment includes a machinery area 20, a storage tank compartment 40A, and a vehicle loading section 100. The ship type of the ship 1 is not limited to a specific ship type as long as it can carry vehicles. Examples of the ship type of the ship 1 include a ferry, a RORO ship (Roll-on / Roll-off ship), a PCTC (Pure Car & Truck Carrier), and the like.

[0027] The hull 2 has a pair of side hulls 3A and 3B that form its outer shell and a bottom hull 4. The side hulls 3A and 3B each include a pair of side outer plates that form the left and right side hulls. The bottom hull 4 includes a bottom outer plate that connects these side hulls 3A and 3B. Through these pair of side hulls 3A and 3B and the bottom hull 4, the outer shell of the hull 2 is U-shaped in a cross-section orthogonal to the bow-stern direction FA.

[0028] The hull 2 includes multiple decks inside it, including a freeboard deck 5 and an upper deck 8. The freeboard deck 5 in this embodiment is the lowest all-through deck among the all-through decks arranged at a position higher than the full-load waterline. The freeboard deck 5 is also the loading deck for vehicles to drive into the hull 2 from the outside when docking. The upper deck 8 is the uppermost all-through deck.

[0029] At least a part of the multiple decks is set as a vehicle deck 7. Vehicles can be loaded on the vehicle deck 7. In the present embodiment, multiple vehicle decks 7 are arranged at intervals in the vertical direction. In the present embodiment, multiple vehicle decks 7 are arranged at a position lower than the freeboard deck 5.

[0030] Figure 2It is a plan sectional view showing the structure on the lowermost vehicle deck in the ship according to the first embodiment of the present invention. Figure 3 It is a sectional view showing the structure of the storage tank compartment in the ship according to the first embodiment of the present invention.

[0031] As Figure 2 , Figure 3 shown, the machinery area 20 is provided in a part within the hull 2. The machinery area 20 is arranged on the stern 2b side in the fore-and-aft direction FA. The machinery area 20 is arranged on the stern 2b side in the fore-and-aft direction FA with respect to the bulkhead 21 provided at a position lower than the freeboard deck 5. The bulkhead 21 is provided to block one side hull 3A, the other side hull 3B, the freeboard deck 5 and, for example, between the lowermost deck 6. Thus, the space between the freeboard deck 5 and the lowermost deck 6 is divided by the transverse bulkhead, that is, the bulkhead 21, in the fore-and-aft direction FA.

[0032] In the present embodiment, the engine room 23 and the fuel preparation compartment 25 are provided in the machinery area 20.

In the engine room 23, a main engine, an auxiliary engine, a generator engine (all not shown), etc. are accommodated. In the present embodiment, the main engine, the auxiliary engine, and the generator engine are driven using LNG (liquefied natural gas) as fuel. In addition, in the present embodiment, the case of using LNG as fuel is taken as an example for explanation, but in addition to LNG, liquefied gas fuels such as LPG (liquefied petroleum gas) or ammonia can also be used.

[0033] The fuel preparation compartment 25 is formed between the bulkhead 21 and the intermediate bulkhead 22. In the fuel preparation compartment 25, equipment 27 such as a vaporizer (not shown) that vaporizes the fuel supplied from the fuel tank 50 described later is accommodated.

[0034] The storage tank compartment 40A houses a fuel tank 50 capable of storing LNG inside. The fuel tank 50 in the present embodiment exemplifies a case where a plurality, specifically two, are arranged in the direction connecting the pair of hulls 3A, 3B, that is, the ship width direction Dw. Each fuel tank 50 is, for example, in a cylindrical shape extending in the horizontal direction. Each fuel tank 50 in the present embodiment is arranged to extend in the fore-and-aft direction FA. In addition, the shape of the fuel tank 50 is not limited to a cylindrical shape, and it can also be spherical, square, etc. And the number of fuel tanks 50 is not limited to two, and for example, only one can be provided or three or more can be provided.

[0035] As Figure 2As shown, the storage tank compartment 40A has a wall portion 41 formed to surround the two fuel tanks 50 when viewed from the vertical direction Dv. The wall portion 41 has a pair of side walls 42A, 42B, a front wall 43A, and a rear wall 44A.

[0036] The pair of side walls 42A, 42B are provided at intervals along the ship width direction Dw. One of the side walls 42A on one side in the ship width direction Dw is separated and provided inward from the side 3A on one side in the ship width direction Dw. The other side wall 42B on the other side in the ship width direction Dw is separated and provided inward from the side 3B on the other side in the ship width direction Dw. The pair of side walls 42A, 42B are each provided to cover the two fuel tanks 50 when viewed from the ship width direction Dw.

[0037] The front wall 43A is provided to connect the ends of the pair of side walls 42A, 42B on the side closer to the bow 2a in the fore-and-aft direction FA. The front wall 43A is provided to cover the two fuel tanks 50 when viewed from the bow 2a side in the fore-and-aft direction FA.

[0038] The rear wall 44A is provided to connect the ends of the pair of side walls 42A, 42B on the side closer to the stern 2b in the fore-and-aft direction FA. The rear wall 44A is provided to cover the two fuel tanks 50 when viewed from the stern 2b side in the fore-and-aft direction FA.

[0039] As Figure 3 shown, the pair of side walls 42A, 42B, the front wall 43A, and the rear wall 44A that constitute the wall portion 41 each stand upright upward from the deck 6 which is the lowermost layer of the vehicle deck 7A. The upper ends of the pair of side walls 42A, 42B, the front wall 43A, and the rear wall 44A are each connected to the lower surface of the freeboard deck 5.

[0040] The wall portion 41 of the storage tank compartment 40A is provided to penetrate through the plurality of vehicle decks 7B to 7D disposed between the lowermost deck 6 and the freeboard deck 5 along the vertical direction Dv. On the vehicle decks 7B to 7D, openings 71B to 71D penetrating along the vertical direction Dv are formed in the portion surrounded by the pair of side walls 42A, 42B, the front wall 43A, and the rear wall 44A that constitute the wall portion 41. In other words, when viewed from above, the vehicle decks 7B to 7D are not provided inside the area surrounded by the wall portion 41 but only at positions more outside than the wall portion 41.

[0041] Here, the rear walls 441A, 441B, and 441C in the floors Fa to Fc provided on the vehicle decks 7A to 7C are arranged at intervals on the side closer to the bow 2a in the fore-and-aft direction FA with respect to the bulkhead 21. In the floor Fd on the vehicle deck 7D directly below the freeboard deck 5, the rear wall 441D is arranged on the side closer to the stern 2b in the fore-and-aft direction FA than the rear walls 441A to 441C in the floors Fa to Fc provided on the vehicle decks 7A to 7C. The rear wall 441D also serves as the bulkhead 21.

[0042] Moreover, in the floor Fd on the vehicle deck 7D, the front wall 431D is arranged on the side closer to the stern 2b in the fore-and-aft direction FA than the front walls 431A to 431C in the floors Fa to Fc provided on the vehicle decks 7A to 7C.

[0043] Each fuel tank 50 is provided, for example, on the lowest deck 6 via a support base (not shown). Each fuel tank 50 is arranged between the lowest deck 6 and the vehicle deck 7D directly below the freeboard deck 5. Each fuel tank 50 is arranged to penetrate the openings 71B and 71C formed in the multi-layer vehicle decks 7B and 7C in the vertical direction Dv.

[0044] In the floor Fd directly below the freeboard deck 5, a storage tank connection space 55 for connecting various pipes to the fuel tank 50 is provided. The storage tank connection space 55 is arranged between the front wall 431D and the rear wall 441D.

[0045] The storage tank connection space 55 is connected to the equipment 27 provided in the fuel preparation compartment 25 via a pipe 200A. The pipe 200A penetrates the bulkhead 21 (rear wall 441D). The pipe 200A transports the fuel stored in the fuel tank 50 to the equipment 27 in the fuel preparation compartment 25 via the storage tank connection space 55. Thus, the pipe 200A connects the inside of the storage tank compartment 40A and the machinery area 20. The pipe 200A is only arranged on the floor Fd of a part of the vehicle decks 7 among the multiple vehicle decks 7.

[0046] Figure 4 It is a plan sectional view showing the structure on the vehicle deck of the floor provided with the connection area in the ship according to the first embodiment of the present invention.

[0047] As Figure 2 、 Figure 4 、 Figure 5As shown, the vehicle loading section 100 is disposed on the bow 2a side with respect to the mechanism area 20 within the hull 2. The vehicle loading section 100 is separated from the mechanism area 20 by a partition wall 21. The vehicle loading section 100 has a plurality of vehicle decks 7A to 7D. The vehicle loading section 100 can load multiple vehicles on each floor Fa to Fd of the vehicle decks 7A to 7D. The vehicle loading section 100 is provided to extend over multiple floors Fa to Fd on the plurality of vehicle decks 7A to 7D.

[0048] As Figure 2 , Figure 4 shown, on each floor Fa to Fc of the vehicle decks 7A to 7C, the vehicle loading section 100 includes a main vehicle loading area 101, a pair of side vehicle loading areas 102A and 102B, and a connection area 103.

[0049] On each floor Fa to Fc of the vehicle decks 7A to 7C, the main vehicle loading area 101 is set on the side closer to the bow 2a in the fore-and-aft direction FA than the front wall 43A (front walls 431A, 431B, 431C) of the storage tank compartment 40A. An inclined road 120 for traveling back and forth between the vehicle decks 7 of other floors is provided in the main vehicle loading area 101.

[0050] A plurality of parking zones P are formed in the main vehicle loading area 101. The plurality of parking zones P are formed between a pair of side hulls 3A and 3B so as to avoid interference with the inclined road 120 and the like. Each parking zone P is set to a size at which a vehicle loaded on the vehicle loading section 100 can park when viewed from above. A plurality of the plurality of parking zones P are arranged in the ship width direction Dw and the fore-and-aft direction FA, respectively.

[0051] A pair of side vehicle loading areas 102A and 102B are formed on two outer sides in the ship width direction Dw with respect to the storage tank compartment 40A. One side vehicle loading area 102A is formed between the side hull 3A and the side wall 42A of the storage tank compartment 40A. The other side vehicle loading area 102B is formed between the side hull 3B and the side wall 42B of the storage tank compartment 40B. The pair of side vehicle loading areas 102A and 102B extend respectively in the fore-and-aft direction FA.

[0052] The side vehicle loading areas 102A and 102B respectively have a width dimension W1 in the ship width direction Dw through which a vehicle can pass and in which a vehicle can park (refer to Figure 2). In the side vehicle loading areas 102A and 102B, a plurality of parking zones P2 are respectively set so that a plurality of vehicles can be loaded. In each of the side vehicle loading areas 102A and 102B, a plurality of parking zones P2 are arranged in the fore-and-aft direction FA. In the present embodiment, an example is shown in which in each of the side vehicle loading areas 102A and 102B, two rows of parking zones P2 are arranged in the ship width direction Dw. The number of parking zones P2 in the ship width direction Dw can be one row or three or more rows.

[0053] On each floor Fa to Fc of the vehicle decks 7A to 7C, the connection area 103 extends in the ship width direction Dw between the machinery area 20 and the tank compartment 40A. The connection area 103 is formed between the bulkhead 21 and the rear wall 44A (rear walls 441A, 441B, 441C). The two end portions of the connection area 103 in the ship width direction Dw connect the pair of side vehicle loading areas 102A and 102B to each other. The pipe 200A is arranged at a position overlapping the connection area 103 when viewed from the up-and-down direction Dv.

[0054] The connection area 103 has a width dimension W2 (refer to Figure 2 ) in which vehicles can pass and park in the fore-and-aft direction FA. In the connection area 103, a plurality of parking zones P3 are set so that a plurality of vehicles can be loaded. In the connection area 103, a plurality of parking zones P3 are arranged in the ship width direction Dw. In the present embodiment, an example is shown in which in the connection area 103, two rows of parking zones P3 are arranged in the fore-and-aft direction FA. The number of parking zones P3 arranged in the fore-and-aft direction FA can be one row or three or more rows.

[0055] Figure 5 is a top plan sectional view showing the structure on the vehicle deck of the floor where the pipe is provided in the ship according to the first embodiment of the present invention.

[0056] As Figure 5 shown, in the floor Fd of the vehicle deck 7D, the vehicle loading portion 100 includes the main vehicle loading area 101. In the floor Fd of the vehicle deck 7D, the main vehicle loading area 101 is set on the side closer to the bow 2a in the fore-and-aft direction FA than the front wall 43A of the tank compartment 40A. A plurality of parking zones P are set in the main vehicle loading area 101. And, in the present embodiment, in the floor Fd of the vehicle deck 7D, the vehicle loading portion 100 includes a pair of side vehicle loading areas 102A and 102B. On the other hand, the vehicle loading portion 100 of the floor Fd of the vehicle deck 7D does not include the connection area 103.

[0057] (Function and effect)

[0058] In the ship 1 of the above-described embodiment, a connection area 103 extending in the ship width direction Dw between the machinery area 20 and the storage tank compartment 40A is provided. This connection area 103 connects the pair of side vehicle loading areas 102A and 102B to each other so that vehicles can pass through. Therefore, a vehicle parked in one of the pair of side vehicle loading areas 102A and 102B can move through the connection area 103 to the other side vehicle loading area 102A and 102B. Thus, even when advancing into and parking in one of the side vehicle loading areas 102A and 102B during boarding, the vehicle can directly advance from the parking position and disembark without changing direction within the side vehicle loading area 102A or 102B. Therefore, the vehicle loading work can be effectively performed.

[0059] Moreover, in addition to the pair of side vehicle loading areas 102A and 102B, vehicles can also be parked in the connection area 103. Therefore, the number of vehicles loaded onto the ship 1 can be increased.

[0060] Also, in the above-described embodiment, the storage tank compartment 40A is formed to penetrate a plurality of vehicle decks 7 in the vertical direction Dv, and the connection area 103 is provided on at least one of the vehicle decks 7A to 7C among the plurality of vehicle decks 7.

[0061] Thus, even when the storage tank compartment 40A is formed to penetrate a plurality of vehicle decks 7 in the vertical direction Dv, on the vehicle decks 7A to 7C where the connection area 103 is provided, a vehicle parked in one of the pair of side vehicle loading areas 102A and 102B can easily move through the connection area 103 to the other side vehicle loading area 102A and 102B.

[0062] Also, in the above-described embodiment, the pipe 200A is only arranged on the floor Fd of a part of the vehicle decks 7 among the plurality of vehicle decks 7.

[0063] According to this structure, in the case of having a pipe 200A connecting the inside of the storage tank compartment 40A and the inside of the machinery area 20, the pipe 200A is only arranged on the floors of a part of the vehicle decks 7 among the plurality of vehicle decks 7. Thus, on the vehicle decks 7A to 7C of the floors Fa to Fc where the pipe 200 is not arranged, vehicles can move through the connection area 103 from one side vehicle loading area 102A and 102B to the other side vehicle loading area 102A and 102B.

[0064] Further, in the above-described embodiment, the connection area 103 has a width dimension W2 that enables a plurality of vehicles to be parked side by side in the fore-and-aft direction FA. Thus, a plurality of vehicles can be parked side by side in the fore-and-aft direction FA in the connection area 103. Therefore, the number of vehicles that can be loaded onto the ship 1 can be increased. Also, since the width dimension W2 of the connection area 103 is increased, it is easy to change the traveling direction of the vehicle between the side vehicle loading areas 102A and 102B extending in the fore-and-aft direction FA and the connection area 103 extending in the ship width direction Dw.

[0065] <Second Embodiment>

[0066] Next, a second embodiment of the ship according to the present invention will be described. In the second embodiment described below, only the structure of the storage tank compartment is different from that of the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

[0074] On the floor Fa of the vehicle deck 7A, the vehicle loading section 100 includes a main vehicle loading area 101 and a pair of side vehicle loading areas 102A and 102B. On the floor Fa of the vehicle deck 7A, the vehicle loading section 100 does not include a connection area 103.

[0075] (Function and effect)

[0076] In the ship 1 of the above embodiment, a connection area 103 extending in the ship width direction Dw between the machinery area 20 and the storage tank compartment 40B is provided. Therefore, similar to the above first embodiment, the vehicle loading work can be effectively performed.

[0077] <Third Embodiment>

[0078] Next, a third embodiment of the ship according to the present invention will be described. In the third embodiment described below, only the structure of the storage tank compartment is different from that of the first embodiment. Therefore, the same reference numerals are used for the parts that are the same as those of the first and second embodiments, and the repeated description is omitted.

[0079] Figure 7 It is a cross-sectional view showing the structure of the storage tank compartment in the ship according to the third embodiment of the present invention.

[0080] As Figure 7 shown, the hull 2 of the ship 1 of this embodiment includes a machinery area 20, a storage tank compartment 40C, and a vehicle loading section 100.

[0081] Similar to the first and second embodiments, the storage tank compartment 40C has a wall portion 41 formed to surround the two fuel tanks 50 when viewed from the vertical direction Dv. The wall portion 41 has a pair of side walls 42A and 42B, a front wall 43A, and a rear wall 44C.

[0082] The rear walls 443A to 443C in the floors Fa to Fc provided on the vehicle decks 7A to 7C in the rear wall 44C are arranged at intervals on the side closer to the bow 2a in the fore-and-aft direction FA with respect to the bulkhead 21. On the other hand, the lower part 4435 of the rear wall 443D in the floor Fd on the vehicle deck 7D directly below the freeboard deck 5 in the rear wall 44C is arranged at the same position in the fore-and-aft direction FA as the rear walls 443A to 443C.

The space between the upper part 4436 and the lower part 4435 of the rear wall 443D is blocked from below by the top plate 4437. The top plate 4437 is set to a height at which a vehicle can travel on the vehicle deck 7D below it.

[0083] The tank connection space 55 is arranged between the front wall 431D and the lower part 4435 of the rear wall 443D. The pipe 200C connecting the tank connection space 55 and the equipment 27 arranged in the fuel preparation compartment 25 penetrates the bulkhead 21 (the upper part 4436 of the rear wall 443D) in the floor Fd. In the pipe 200C, when viewed from the vertical direction Dv, the pipe 200C in the floor Fd is arranged at a position overlapping the connection area 103 in the floor Fd. The pipe 200C is arranged at a position higher than the top plate 4437 at the position overlapping the connection area 103 in the floor Fd. Thus, the pipe 200C is arranged to protrude upward from the vehicle deck 7D in the floor Fd by a height higher than the height at which a vehicle can pass.

[0084] The vehicle loading part 100 includes a main vehicle loading area 101, a pair of side vehicle loading areas 102A and 102B, and a connection area 103 in each of the floors Fa to Fd on the vehicle decks 7A to 7D. In the floor Fd, the pipe 200C and the top plate 4437 are arranged to protrude upward from the vehicle deck 7D in the connection area 103 by a height higher than the height at which a vehicle can pass. Therefore, in the floor Fd, the connection area 103 also allows vehicles to pass through.

[0085] (Function and effect)

[0086] Similar to the above-described first embodiment and second embodiment, in the ship 1 of the above-described embodiment, there is also provided a connection area 103 extending in the ship width direction Dw between the machinery area 20 and the tank compartment 40C. Therefore, the vehicle loading work can be effectively performed.

[0087] Further, in the above-described embodiment, when the pipe 200C connecting the inside of the storage tank compartment 40 and the inside of the machinery area 20 is arranged at a position overlapping the connection area 103 when viewed from the vertical direction, the pipe 200C is arranged to protrude upward from the upper surface of the vehicle deck 7 of the floor by a height greater than the height that a vehicle can pass through. Thus, when the pipe 200C is provided, a vehicle can pass under the pipe 200C when passing through the connection area 103. Therefore, the vehicle can pass through the connection area 103 and move from one side vehicle loading area 102A, 102B to the other side vehicle loading area 102A, 102B.

[0088] <Fourth Embodiment>

[0089] Next, a fourth embodiment of the ship according to the present invention will be described. In the fourth embodiment described below, only the structure of the storage tank compartment is different from that of the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, and repeated descriptions are omitted.

[0090] Figure 8 It is a cross-sectional view taken in the bow-stern direction showing the structure of the storage tank compartment in the ship according to the fourth embodiment of the present invention. Figure 9 It is a view showing the structure of the storage tank compartment in the ship according to the fourth embodiment of the present invention, and is Figure 8 a cross-sectional view taken along the line A-A.

[0091] As Figure 8 , Figure 9 shown, the hull 2 of the ship 1 of this embodiment includes a machinery area 20, a storage tank compartment 40D, and a vehicle loading section 100.

[0092] In the present embodiment, functional zones 70A and 70B are provided at the bottom inside the hull 2. The functional zones 70A and 70B are provided as side rolling water tanks, ballast tanks, fin stabilizer device tanks, sewage treatment device tanks, etc. The functional zone 70A is provided between the storage tank compartment 40D and the side 3A in the ship width direction Dw. The functional zone 70B is provided between the storage tank compartment 40D and the side 3B in the ship width direction Dw. The functional zones 70A and 70B extend in the bow-stern direction FA.

[0093] As Figure 9 shown, the functional zones 70A and 70B are adjacent to both the storage tank compartment 40D and the machinery area 20. The functional zone 70A is adjacent to the storage tank compartment 40D across the side wall 42A of the storage tank compartment 40D. The functional zone 70B is adjacent to the storage tank 40 across the side wall 42B of the storage tank compartment 40D. The functional zone 70B is adjacent to the machinery area 20 across the partition wall 24B provided on the other side in the ship width direction Dw of the machinery area 20.

[0094] The storage tank connection space 55 (refer to Figure 8 ) is connected to the equipment 27 disposed in the fuel preparation compartment 25 via a pipe 200D. The pipe 200D is disposed in the functional zone 70B through the side wall 42B and the partition wall 24B in the floor Fa on the lowest vehicle deck 7A, i.e., the deck 6 (refer to Figure 9 ).

[0095] As Figure 8 shown, on each of the floors Fb to Fd of the vehicle decks 7B to 7D, the vehicle loading section 100 includes a main vehicle loading area 101 (refer to Figure 9 ), a pair of side vehicle loading areas 102A and 102B, and a connection area 103.

[0096] In addition, the case where the pipe 200D passes through the functional zone 70B is taken as an example for illustration, but it may also pass through the functional zone 70A, or pass through both the functional zones 70A and 70B. Moreover, at least one of the functional zones 70A and 70B may be set as the fuel preparation compartment 25.

[0097] (Function and effect)

[0098] In the ship 1 of the above embodiment, when the functional zone 70B adjacent to both the storage tank compartment 40D and the machinery area 20 is provided, by making the pipe 200D pass through the functional zone 70B, it is possible to prevent the connection area 103 from being blocked by the pipe 200D on the vehicle decks 7B to 7D of the other floors Fb to Fd. Therefore, the vehicle loading work can be effectively carried out.

[0099] <Fifth Embodiment>

[0100] Next, a fifth embodiment of the ship according to the present invention will be described. In the fifth embodiment described below, only the structure of the storage tank compartment is different from that of the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals for description, and repeated descriptions are omitted.

[0101] Figure 10 is a top view cross-sectional view showing the structure of the storage tank compartment in the ship according to the fifth embodiment of the present invention.

[0102] The hull 2 of the ship 1 of this embodiment includes a machinery area 20, a storage tank compartment 40E, and a vehicle loading section 100.

[0103] The storage tank compartment 40E accommodates, for example, two fuel tanks 50A and 50B inside thereof. In the present embodiment, similarly to the first to fourth embodiments, two fuel tanks 50A and 50B are arranged, for example, in the direction connecting a pair of side hulls 3A and 3B, that is, in the ship width direction Dw. The fuel tanks 50A and 50B are each, for example, in the shape of a cylinder extending in the horizontal direction. The fuel tanks 50A and 50B are each arranged to extend in the fore-and-aft direction FA. The storage tank length L2 of a part of the plurality of fuel tanks 50A and 50B, that is, the fuel tank 50B in the fore-and-aft direction FA is shorter than the storage tank length L1 of the remaining fuel tanks 50A in the fore-and-aft direction FA. Specifically, the positions of the respective ends of the fuel tank 50A and the fuel tank 50B on the side closer to the stern 2b in the fore-and-aft direction FA are the same. On the other hand, the end of the fuel tank 50B on the side closer to the bow 2a is located on the side closer to the stern 2b than the end of the fuel tank 50A on the side closer to the bow 2a.

[0104] The storage tank compartment 40E has a wall portion 41E formed to surround the two fuel tanks 50A and 50B when viewed from the up-and-down direction Dv. The wall portion 41E has a pair of side walls 42A and 42B, a front wall 43E, and a rear wall 44A.

[0105] The front wall 43E has a first front wall portion 435 and a second front wall portion 436.

[0106] The first front wall portion 435 is arranged on the bow 2a side in the fore-and-aft direction FA with respect to the fuel tank 50B. The second front wall portion 436 is arranged on the bow 2a side in the fore-and-aft direction FA with respect to the fuel tank 50A. The first front wall portion 435 is arranged on the side closer to the stern 2b in the fore-and-aft direction FA than the second front wall portion 436. The space between the first front wall portion 435 and the second front wall portion 436 is blocked by an intermediate wall 433 extending in the fore-and-aft direction FA.

[0107] Here, with respect to the front wall 43E on the floors Fa to Fd provided on the vehicle decks 7A to 7D, a main vehicle loading area 101E is set on the side closer to the bow 2a in the fore-and-aft direction FA. An inclined road 120 for traveling back and forth between the vehicle decks 7 of other floors is provided in the main vehicle loading area 101E. The inclined road 120 is arranged on the bow 2a side in the fore-and-aft direction FA with respect to the first front wall portion 435.

[0108] (Function and effect)

[0109] In the ship 1 of the above-described embodiment, the first front wall portion 435 is disposed at a position closer to the stern 2b side in the fore-and-aft direction FA than the second front wall portion 436. Thus, with respect to the first front wall portion 435, it is possible to ensure a relatively long space for the main vehicle loading area 101E of the vehicle loading portion 100 on the bow 2a side in the fore-and-aft direction FA toward the side closer to the stern 2b. By arranging the inclined road 120 in such a space, in the main vehicle loading area 101E where the length of the space in the fore-and-aft direction FA is limited, it is possible to ensure a space for arranging the inclined road 120 and a passage space for the vehicle lifted by the inclined road 120.

[0110] Also, similar to the above-described embodiments, by providing the connection area 103, it is possible to effectively perform the vehicle loading work.

[0111] (Other embodiments)

[0112] As described above, the embodiments of the present invention have been described in detail with reference to the drawings, but the specific structure is not limited to this embodiment, and also includes design changes and the like within the scope not departing from the gist of the present invention.

[0113] In the above-described embodiments, it is assumed that two fuel tanks 50 are provided or two fuel tanks 50A and 50B are provided, but the number of fuel tanks provided is not limited to two. Also, the shape, arrangement, etc. of the fuel tanks can be appropriately changed.

[0114] Moreover, in the above-described embodiment, it is assumed that the storage tank compartments 40A to 40D are provided over the floors Fa to Fd on the vehicle decks 7A to 7D, but the number of floors can be appropriately changed.

[0115] Also, in the above-described embodiment, it is assumed that the fuel preparation compartment 25 is provided within the machinery area 20, but the fuel preparation compartment 25 may not be provided in the machinery area 20. For example, the fuel preparation compartment 25 can be provided at a position different from the machinery area 20 and the storage tank compartment 40A, or it can be housed within the storage tank compartment 40A.

[0116] <Supplementary Note>

[0117] The ship 1 described in each embodiment can be understood as follows, for example.

[0118] (1) The ship 1 according to the first mode includes: a hull 2 having a pair of side hulls 3A and 3B and a bottom 4; a machinery area 20 provided in a part of the hull 2; a vehicle loading section 100 provided on the bow 2a side of the machinery area 20 in the hull 2 and separated from the machinery area 20, and having a vehicle deck 7 capable of loading multiple vehicles; and storage tanks 40A to 40E provided separately from the pair of side hulls 3A and 3B and accommodating fuel tanks 50 therein. The vehicle loading section 100 includes: a pair of side vehicle loading areas 102A and 102B extending in the fore-and-aft direction FA between the pair of side hulls 3A and 3B and the storage tanks 40A to 40E and capable of loading the vehicles; and a connecting area 103 extending in the ship width direction Dw between the machinery area 20 and the storage tanks 40 and connecting the pair of side vehicle loading areas 102A and 102B to each other so that the vehicles can pass through.

[0119] The ship 1 includes a connecting area 103 extending in the ship width direction Dw between the machinery area 20 and the storage tanks 40A to 40E. The connecting area 103 connects the pair of side vehicle loading areas 102A and 102B to each other so that the vehicles can pass through. Therefore, the vehicle parked in one of the pair of side vehicle loading areas 102A and 102B can move through the connecting area 103 to the other side vehicle loading area 102A and 102B. Therefore, even when the vehicle advances and parks in one of the side vehicle loading areas 102A and 102B during boarding, the vehicle can directly advance and disembark from the parking position without changing the direction within the side vehicle loading area 102A or 102B. Therefore, the vehicle loading work can be effectively performed.

[0120] In addition, in addition to the pair of side vehicle loading areas 102A and 102B, vehicles can also be parked in the connecting area 103. Therefore, the number of vehicles loaded on the ship 1 can be increased.

[0121] (2) The ship 1 according to the second mode is the ship 1 of (1), wherein a plurality of vehicle decks 7 are provided at intervals in the vertical direction, the storage tanks 40A to 40E are formed to penetrate through the plurality of vehicle decks 7 in the vertical direction, and the connecting area 103 is provided on at least one of the plurality of vehicle decks 7.

[0122] Accordingly, even when the storage tank compartments 40A to 40E are formed to penetrate a plurality of vehicle decks 7 in the vertical direction, on the vehicle deck 7 provided with the connection area 103, the vehicle parked in one of the pair of side vehicle loading areas 102A, 102B can move through the connection area 103 to the other side vehicle loading area 102A, 102B.

[0123] The ship 1 according to the third mode is the ship 1 of (2), and further includes pipes 200A to 200E connecting the inside of the storage tank compartments 40A to 40E and the inside of the machinery area 20, and the pipes 200A to 200E are only arranged on the floors of a part of the plurality of vehicle decks 7.

[0124] According to this structure, in the case of having pipes 200A to 200E connecting the inside of the storage tank compartments 40A to 40E and the inside of the machinery area 20, the pipes 200A to 200E are only arranged on the floors of a part of the plurality of vehicle decks 7. Accordingly, on the floors where the pipes 200A to 200E are not arranged, the vehicle can move through the connection area 103.

[0125] The ship 1 according to the fourth mode is the ship 1 of (3), wherein the pipe 200C is arranged at a position overlapping with the connection area 103 when viewed from the vertical direction Dv, and is arranged to protrude upward from the upper surface of the vehicle deck 7 of the floor by a height higher than the height that the vehicle can pass through.

[0126] According to this structure, in the case where the pipe 200C connecting the inside of the storage tank compartment 40C and the inside of the machinery area 20 is arranged at a position overlapping with the connection area 103 when viewed from the vertical direction Dv, the pipe 200C is arranged to protrude upward from the upper surface of the vehicle deck 7 of the floor by a height higher than the height that the vehicle can pass through. Accordingly, in the case of having the pipe 200C, when the vehicle passes through the connection area 103, it can also pass through below the pipe 200C without interference. Therefore, the vehicle can move through the connection area 103.

[0127] The ship 1 according to the fifth mode is the ship 1 of (3), and includes functional areas 70A, 70B provided between the storage tank compartment 40D and the hull sides 3A, 3B in the ship width direction Dw, extending in the fore-and-aft direction FA, and adjacent to both the storage tank compartment 40D and the machinery area 20, and the pipe 200D is arranged in the functional areas 70A, 70B.

[0128] According to this structure, the pipe 200D is arranged within the functional areas 70A and 70B which are provided between the storage tank compartment 40D and the ship's sides 3A and 3B in the ship width direction Dw, extend in the fore-and-aft direction FA, and are adjacent to both the storage tank compartment 40D and the machinery area 20. Thus, when the functional areas 70A and 70B are provided, it is possible to prevent the connection area 103 from being blocked by the pipe 200D on the vehicle decks 7B to 7D of the other floors Fb to Fd.

[0129] (6) The ship 1 according to the sixth aspect is any one of the ships 1 in (1) to (5), wherein the connection area 103 has a width dimension W2 capable of arranging and parking a plurality of the vehicles in the fore-and-aft direction FA.

[0130] According to this structure, the connection area 103 has a width dimension W2 capable of arranging and parking a plurality of vehicles in the fore-and-aft direction FA. Thus, in the connection area 103, a plurality of vehicles can be arranged and parked in the fore-and-aft direction FA. Therefore, it is possible to increase the number of vehicles loaded on the ship 1. And since the width dimension W2 of the connection area 103 becomes larger, it is easy to change the traveling direction of the vehicle between the side vehicle loading areas 102A and 102B extending in the fore-and-aft direction FA and the connection area 103 extending in the ship width direction Dw.

[0131] (7) The ship 1 according to the seventh aspect is any one of the ships 1 in (1) to (6), wherein the fuel tanks 50A and 50B are arranged side by side in the ship width direction Dw, and the tank length L2 in the fore-and-aft direction FA of a part of the plurality of fuel tanks 50B is shorter than the tank length L1 in the fore-and-aft direction FA of the remaining fuel tanks 50A. The storage tank compartment 40 includes: a first front wall portion 435 disposed on the bow 2a side in the fore-and-aft direction FA with respect to a part of the fuel tanks 50B; and a second front wall portion 436 disposed on the bow 2a side in the fore-and-aft direction FA with respect to the other fuel tanks 50A, and the first front wall portion 435 is disposed at a position closer to the stern 2b side in the fore-and-aft direction FA than the second front wall portion 436.

[0132] According to this structure, the first front wall portion 435 disposed on the bow 2a side with respect to a part of the fuel tanks 50B having a shorter tank length in the fore-and-aft direction FA is disposed at a position closer to the stern 2b side than the second front wall portion 436 disposed on the bow 2a side with respect to the other fuel tanks 50A. Thus, it is possible to ensure a longer space for the vehicle loading portion 100 on the bow 2a side in the fore-and-aft direction FA toward the stern 2b side with respect to the first front wall portion 435.
