DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (Overall configuration of the ship) Hereinafter, a vessel according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 4. FIG. As shown in Fig. 1, the ship 1 of this embodiment includes a hull 2, a superstructure 7, a heat engine 20, a plurality of liquefied gas tanks 30, and a fuel supply device 40. The type of the ship 1 is not limited to a specific one. Examples of the type of the ship 1 include a ferry, a RORO ship (Roll-on / Roll-off ship), and a PCTC (Pure Car & Truck Carrier).

[0010] The hull 2 ​​has a pair of side panels 3A, 3B that form its outer hull, and a ship bottom 4. The side panels 3A, 3B are made up of a pair of side panel shells that form the port and starboard sides, respectively. The ship bottom 4 is made up of a bottom panel that connects the side panels 3A, 3B. The pair of side panels 3A, 3B and the ship bottom 4 give the outer hull 2 ​​a U-shape in a cross section perpendicular to the bow-stern direction FA.

[0011] The hull 2 ​​has a plurality of decks 5 therein. The plurality of decks 5 are arranged at intervals in the vertical direction Dv of the hull 2. Some of the plurality of decks 5 are defined as full decks 5S. The full deck 5S is arranged continuously from the bow section 2a on the bow side in the bow-stern direction FA of the hull 2 ​​to the stern section 2b on the stern side in the bow-stern direction FA. Of the full decks 5S arranged above the load waterline, the full deck 5S arranged at the lowest level is the freeboard deck 53. Of the full decks 5S, the full deck 5S arranged at the highest level is the upper deck 55. The upper deck 55 in this embodiment is an exposed deck 8A exposed to the outside. The hull 2 ​​illustrated in this embodiment further has a bottom deck 6 below the freeboard deck 53.

[0012] (Engine Room Configuration) As shown in FIG. 2, the hull 2 ​​is provided with an aft bulkhead 11 and a forward bulkhead 12 between the freeboard deck 53 and the bottom deck 6. The aft bulkhead 11 and the forward bulkhead 12 are arranged at an interval in the bow-stern direction FA. The aft bulkhead 11 and the forward bulkhead 12 extend from the ship's side 3A to the ship's side 3B, respectively, and also extend from the freeboard deck 53 to the bottom deck 6, respectively. In other words, the space between the freeboard deck 53 and the bottom deck 6 is divided in the bow-stern direction by the aft bulkhead 11 and the forward bulkhead 12. In this embodiment, the compartment between the freeboard deck 53 and the bottom deck 6 and between the aft bulkhead 11 and the forward bulkhead 12 is defined as an engine room 10 (in other words, a main engine room).

[0013] (Holding configuration) As shown in Fig. 1, a hold 15 for carrying cargo and the like is provided inside the hull 2. The hull 2 ​​illustrated in this embodiment has vehicles carried in the hold 15. Therefore, among the multiple decks 5 illustrated in this embodiment, the decks 51-54 arranged below the upper deck 55 are vehicle decks 5C on which vehicles can enter. The decks 51, 52 arranged below the freeboard deck 53 are provided on the bow side in the bow-stern direction FA with respect to the forward bulkhead 12.

[0014] (Superstructure configuration) The superstructure 7 is provided on the upper deck 55 of the hull 2. The superstructure 7 has multiple decks 71-74 inside it. The multiple decks 71-74 are provided at intervals in the vertical direction Dv on the superstructure 7. The deck 74 located at the top (upper surface) of the superstructure 7 is an exposed deck 8B that is exposed to the outside. The decks 71-73 within the superstructure 7 are used as an accommodation area 75 in which passenger cabins, dining rooms, etc. are provided.

[0015] (Structure of a heat engine) The heat engine 20 is accommodated in the engine room 10. The heat engine 20 is an internal combustion engine or an external combustion engine that uses liquefied gas as fuel. The ship 1 in this embodiment is equipped with a main engine 21 and a generator engine 22 as the heat engine 20. The main engine 21 exerts a propulsive force for sailing the ship 1. The main engine 21 rotates a screw 9 provided outside the stern section 2b of the hull 2. The main engine 21 may be, for example, a steam turbine, a gas turbine, a reciprocating engine, or the like.

[0016] The generator engine 22 drives a generator (not shown). For example, a gas turbine or a reciprocating engine can be used as the generator engine 22. Rotational energy generated by the generator engine 22 is converted into electrical energy by the generator and supplied to each part in the hull 2.

[0017] (Configuration of liquefied gas tank) As shown in Figs. 2 and 3, a plurality of liquefied gas tanks 30 are provided on the upper deck 55, which is the exposed deck 8A, at intervals in the ship's width direction W. The liquefied gas tanks 30 are dedicated fuel tanks for storing liquefied gas such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG) that serve as fuel for the main engine 21 and the generator engine 22. In this embodiment, two liquefied gas tanks 30 are provided. In this embodiment, the liquefied gas tank 30 is provided on the upper deck stern section 55b located on the stern side in the bow-stern direction FA of the upper deck 55. This embodiment further illustrates a case in which these two liquefied gas tanks 30 are symmetrically arranged on either side of the center C (indicated by a dashed line) in the ship's width direction W.

[0018] 2, the ship 1 is provided with a vent riser 31 extending upward. The vent riser 31 discharges boil-off gas vaporized in the liquefied gas tank 30 in an emergency or the like.

[0019] (Bunker Station Configuration) The ship 1 is equipped with a bunker station 33. The bunker station 33 loads and unloads the liquefied gas tank 30 between the bunker station 33 and outboard equipment such as onshore equipment. The bunker station 33 is equipped with a connection port that can be connected to outboard equipment such as onshore equipment, a connection pipe that connects the connection port and the liquefied gas tank 30, and a loading pump and the like (none of which are shown) for supplying liquefied gas through the connection pipe.

[0020] The ship 1 is equipped with piping 35 that connects the bunker station 33 and the liquefied gas tanks 30. The piping 35 is inserted into a first duct 36 formed in the hull 2. The lower end of the first duct 36 is connected to the bunker station 33. The upper end of the first duct 36 opens upward on the upper deck 55. The piping 35 that extends from inside the first duct 36 to above the upper deck 55 is connected to each liquefied gas tank 30 through a fuel supply device 40 described later (not shown in FIG. 3).

[0021] (Configuration of the fuel supply system) The fuel supply device 40 vaporizes the liquefied gas stored in the liquefied gas tank 30 and supplies it to the heat engine 20 (the main engine 21, the generator engine 22). As shown in FIG. 4, the fuel supply device 40 mainly includes a pump 41, an evaporator 42, a gas heater 43, a buffer tank 44, and a casing 45. The pump 41 sends out the liquefied gas G1 in the liquefied gas tank 30 to a fuel supply pipe 46 described later. The evaporator 42 evaporates and vaporizes the liquefied gas G1 to generate a fuel gas G2. The gas heater 43 heats and pressurizes the boil-off gas G3 generated in the liquefied gas tank 30. The buffer tank 44 temporarily stores the fuel gas G2 generated by the evaporator 42. The casing 45 forms the outer shell of the fuel supply device 40 and has a hollow box shape. The casing 45 houses the pump 41, the evaporator 42, the gas heater 43, and the buffer tank 44 inside.

[0022] The fuel supply pipe 46 connects the fuel supply device 40 and the main engine 21. The fuel supply pipe 46 further connects the fuel supply device 40 and the generator engine 22. As shown in Figures 2 and 3, the fuel supply pipe 46 is inserted into a second duct 47 formed in the hull 2. The lower end of the second duct 47 is connected to the engine room 10. The fuel supply pipe 46 extending from the lower end of the second duct 47 into the engine room 10 is connected to the main engine 21 and the generator engine 22. The upper end of the second duct 47 opens upward on the upper deck 55. The fuel supply pipe 46 extending from inside the second duct 47 above the upper deck 55 is connected to the buffer tank 44 inside the casing 45 of the fuel supply device 40.

[0023] The pump 41 sucks out the liquefied gas G1 in the liquefied gas tank 30. The liquefied gas G1 sucked out by the pump 41 is vaporized by evaporation in the evaporator 42 to become the fuel gas G2. The fuel gas G2 is supplied to the heat engine 20 (the main engine 21, the generator engine 22) in the engine room 10 through the buffer tank 44 and the fuel supply piping 46. The boil-off gas G3 pressurized by the gas heater 43 is combusted in a gas incinerator 48 provided outside the fuel supply device 40.

[0024] (Fuel supply system layout) As shown in FIG. 3, the fuel supply device 40 is disposed on the upper deck 55, which is the exposed deck 8A, so as to be sandwiched between a plurality of liquefied gas tanks 30 in the ship width direction W. The fuel supply device 40 in this embodiment is disposed on the center C (indicated by a dashed line) in the ship width direction W of the hull 2. The fuel supply device 40 in this embodiment is provided on the upper deck stern part 55b of the exposed deck 8A. Specifically, the liquefied gas tank 30 and the fuel supply device 40 are provided side by side on the upper deck 55 (exposed deck 8A) of the upper deck 55, which is an exposed deck exposed to the outside air in the ship 1, and the deck 74 (exposed deck 8B, etc.) of the superstructure 7. By disposing the liquefied gas tank 30 and the fuel supply device 40 on the upper deck 55 in this way, the ship 1 has a lower center of gravity than when the liquefied gas tank 30 and the fuel supply device 40 are disposed on the deck 74 of the superstructure 7. In the ship 1 in this embodiment, a vehicle deck 5C on which vehicles are loaded is provided below the upper deck stern portion 55b of the exposed deck 8A (upper deck 55) on which the liquefied gas tank 30 and the fuel supply device 40 are arranged.

[0025] In a side view seen from the ship width direction W shown in FIG. 2, at least a part of the fuel supply device 40 is arranged so as to overlap with the plurality of liquefied gas tanks 30 in the bow-stern direction FA. In this embodiment, a case is illustrated in which all of the fuel supply device 40 is arranged so as to overlap with the plurality of liquefied gas tanks 30 in the side view. In other words, all of the casings 45 of the fuel supply device 40 in this embodiment overlap with the plurality of liquefied gas tanks 30 in the side view. The length L1 of the casing 45 in the bow-stern direction FA is equal to or less than the length L2 of the liquefied gas tank 30 in the bow-stern direction FA. The first end 45a on the bow side in the bow-stern direction FA of the casing 45 is arranged aft of the front end 30a on the bow side of the liquefied gas tank 30. The second end 45b on the aft side in the bow-stern direction FA of the casing 45 is arranged bow of the rear end 30b on the aft side of the liquefied gas tank 30.

[0026] In this embodiment, the liquefied gas tank 30 and the fuel supply device 40 are positioned aft, away from the funnel 70, which is located furthest aft of the superstructure 7 arranged on the exposed deck 8A, with a gap Ss between them (see Figures 2 and 3).

[0027] The ship 1 is provided with a mooring section Sk on the stern side of the liquefied gas tank 30 and the fuel supply device 40. The mooring section Sk is provided with a mooring device 50 for mooring the hull 2 ​​on the exposed deck 8A. Examples of the mooring device 50 include a mooring machine that pays out a mooring rope, a bollard that fastens the mooring rope, a fairlead, etc. (Action and effect) In the ship 1 of the above embodiment, the fuel supply device 40 is disposed between a plurality of liquefied gas tanks 30 provided at intervals in the ship's width direction W. This eliminates the need to install the fuel supply device 40 at a position different from the liquefied gas tanks 30 in the bow-stern direction FA or the up-down direction Dv. This makes it possible to efficiently arrange the liquefied gas tanks 30 and the fuel supply device 40 in a limited space in the ship 1.

[0028] In the ship 1 of the above embodiment, the liquefied gas tank 30 and the fuel supply device 40 are provided on the exposed deck 8A on the aft side in the bow-stern direction FA of the exposed deck 8A. This allows the space on the exposed deck 8A on the aft side in the bow-stern direction FA of the exposed deck 8A to be used as an installation space for the liquefied gas tank 30 and the fuel supply device 40.

[0029] In the ship 1 of the above embodiment, the superstructure 7 is provided on the bow side of the liquefied gas tank 30 and the fuel supply device 40 in the bow-stern direction FA with a gap Ss. This allows the space between the liquefied gas tank 30 and the fuel supply device 40 and the superstructure 7 in the bow-stern direction FA to be used as a space for laying the fuel supply pipe 46, for example. In addition, if the superstructure 7, the liquefied gas tank 30, and the fuel supply device 40 are arranged sufficiently apart, it is not necessary to adopt an explosion-proof structure for the electrical equipment of the superstructure 7 in case of fuel leakage from the liquefied gas tank 30 and the fuel supply device 40, for example, and it is also possible to suppress an increase in costs. In addition, by isolating the living space 75 of the superstructure 7 from the liquefied gas tank 30 and the fuel supply device 40, the safety of the crew, including passengers, can be improved.

[0030] In the ship 1 of the above embodiment, a mooring section Sk equipped with a mooring device 50 is provided on the stern side of the liquefied gas tanks 30 and the fuel supply device 40. When this mooring section Sk is provided, by disposing the fuel supply device 40 between the liquefied gas tanks 30 as described above, it is possible to ensure installation space for the mooring section Sk. This makes it possible to prevent the length of the hull 2 ​​in the bow-stern direction from increasing.

[0031] In the ship 1 of the above embodiment, the vehicle deck 5C is provided below the exposed deck 8A on which the liquefied gas tank 30 and the fuel supply device 40 are provided. Therefore, even if the liquefied gas tank 30 and the fuel supply device 40 are provided, a vehicle mounting space on the vehicle deck 5C can be secured without increasing the length of the hull 2. Therefore, an increase in the length of the hull 2 ​​in the bow-stern direction can be suppressed.

[0032] (Modification of the embodiment) In the above embodiment, the fuel supply device 40 is provided between the two liquefied gas tanks 30 spaced apart in the ship width direction W, but the present invention is not limited to this. 5, for example, four liquefied gas tanks 30 may be provided on the exposed deck 8A at intervals in the transverse direction W of the ship. In this case, the fuel supply device 40 is disposed between two liquefied gas tanks 30 on one side in the transverse direction W of the ship and two liquefied gas tanks 30 on the other side in the transverse direction W of the ship. 6, a plurality of (e.g., two) liquefied gas tanks 30 spaced apart in the ship's width direction W may be provided on the exposed deck 8A in a plurality of sets (e.g., two sets) in the fore-aft direction FA. In this case, the fuel supply device 40 is disposed between the plurality of liquefied gas tanks 30 lined up in the fore-aft direction FA on one side of the ship's width direction W and the plurality of liquefied gas tanks 30 lined up in the fore-aft direction FA on the other side of the ship's width direction W.

[0033] (Other embodiments) Although the embodiment of the present disclosure has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like are also included within the scope that does not depart from the gist of the present disclosure.

[0034] In the above embodiment, as shown in Fig. 3, the height dimension of the fuel supply device 40 is smaller than the height dimension of the liquefied gas tank 30. However, the height dimension of the fuel supply device 40 may be larger than the height dimension of the liquefied gas tank 30.

[0035] In the above embodiment, the liquefied gas tank 30 and the fuel supply device 40 are provided on the stern side of the exposed deck 8A in the fore-aft direction FA, but this is not limited to the above. The liquefied gas tank 30 and the fuel supply device 40 may be provided in the middle part of the exposed deck 8A in the fore-aft direction FA or in the bow side part of the fore-aft direction FA.

[0036] In the above embodiment, the main engine 21 and the generator engine 22 are shown as the heat engine 20, but the present invention is not limited thereto. The heat engine 20 to which the fuel gas G2 is supplied from the liquefied gas tank 30 may be only one of the main engine 21 and the generator engine 22. In that case, the other to which the fuel gas G2 is not supplied may be a heat engine using a fuel other than the fuel gas G2, an electric motor, or the like.

[0037] <Additional Notes> The ship 1 described in the embodiment can be understood, for example, as follows.

[0038] (1) A ship 1 in a first embodiment comprises a hull 2 ​​having a pair of ship sides 3A, 3B and a ship bottom 4, a heat engine 20 provided in an engine room 10 within the hull 2, an exposed deck 8A provided between the pair of ship sides 3A, 3B, a plurality of liquefied gas tanks 30 provided on the exposed deck 8A at intervals in the ship's width direction W, and a fuel supply device 40 provided so as to be sandwiched between the plurality of liquefied gas tanks 30 on the exposed deck 8A, which vaporizes the liquefied gas contained in the liquefied gas tanks 30 and supplies it to the heat engine 20. An example of an exposed deck 8A is Upper Deck 55.

[0039] In this ship 1, the fuel supply device 40 is disposed between a plurality of liquefied gas tanks 30 provided at intervals in the ship's width direction W. This eliminates the need to install the fuel supply device 40 at a position different from the liquefied gas tanks 30 in the bow-stern direction FA or the up-down direction Dv. This makes it possible to efficiently arrange the liquefied gas tanks 30 and the fuel supply device 40 in the limited space of the ship 1.

[0040] (2) The ship 1 of a second aspect is the ship 1 of (1), in which the liquefied gas tank 30 and the fuel supply device 40 are provided on the stern side of the exposed deck 8A in the bow-stern direction FA.

[0041] In this ship 1, the liquefied gas tank 30 and the fuel supply device 40 are provided on the stern side in the bow-stern direction FA on the exposed deck 8A. This allows the space on the exposed deck 8A on the stern side in the bow-stern direction FA of the liquefied gas tank 30 and the fuel supply device 40 to be effectively used for purposes other than the installation space for the liquefied gas tank 30 and the fuel supply device 40.

[0042] (3) The ship 1 of the third aspect is the ship 1 of (2), further comprising an upper structure 7 provided on the exposed deck 8A on the bow side in the bow-stern direction FA relative to the liquefied gas tank 30 and the fuel supply device 40, with a gap Ss between the liquefied gas tank 30 and the fuel supply device 40.

[0043] In this ship 1, the space on the stern side in the bow-stern direction FA relative to the liquefied gas tank 30 and the fuel supply device 40 can be used to provide the superstructure 7. Furthermore, by providing a gap Ss between the liquefied gas tank 30 and the fuel supply device 40, the superstructure 7 does not need to be explosion-proof in case of fuel leakage from the liquefied gas tank 30 and the fuel supply device 40, and an increase in costs can be suppressed. Furthermore, by isolating the superstructure 7 from the liquefied gas tank 30 and the fuel supply device 40, the safety of the crew, including passengers, can be improved.

[0044] (4) The ship 1 of the fourth aspect is the ship 1 of (2) or (3), further comprising a mooring section Sk provided on the exposed deck 8A on the stern side in the bow-stern direction FA relative to the liquefied gas tank 30 and the fuel supply device 40, and equipped with a mooring device 50 for mooring the hull 2.

[0045] In this ship 1, the space on the stern side in the bow-stern direction FA relative to the liquefied gas tank 30 and the fuel supply device 40 can be effectively used as a mooring section Sk.

[0046] (5) The ship 1 of the fifth aspect is any one of the ships 1 of (1) to (4), and further includes a vehicle deck 5C on which vehicles are mounted below the exposed deck 8A in the portion in which the liquefied gas tank 30 and the fuel supply device 40 are provided.

[0047] In this ship 1, a vehicle deck 5C is provided below the exposed deck 8A in a portion where the liquefied gas tank 30 and the fuel supply device 40 are provided. Since the vehicle deck 5C is not part of the accommodation area 75, the safety of the crew, including passengers, is improved. [Explanation of symbols]
