Description

[Technical field]

[0001] The present invention relates to a support structure for an accommodation area of ​​a ship, and more specifically, to a support structure for an accommodation area of ​​a ship in which the accommodation area is T-shaped when viewed from the front and a fuel tank is placed under a T-shaped overhang in the ship's width direction to firmly support the accommodation area. [Background technology]

[0002] A ship's accommodation areas consist of navigational areas (such as the pilothouse), work areas (such as air conditioning rooms, laundry rooms), accommodation areas (crew rooms), public rooms (dining rooms, recreation rooms, etc.), sanitary areas (public toilets, public bathrooms, etc.), cooking areas (galleys), etc., and although they are located near the stern, visibility ahead of the ship is required for maneuvering. Conventionally, the accommodation space of a ship has been arranged on the upper deck in consideration of forward visibility, and its shape is generally box-shaped when viewed from the front. In addition, there are few cases where the fuel tank of a ship is arranged on the upper deck, and there are few cases where the fuel tank is arranged next to the accommodation space. If a fuel tank is placed next to this type of accommodation space on the upper deck, which is box-shaped when viewed from the front, the width of the accommodation space must be narrowed to make it elongated in the length direction of the ship, in which case the height of the accommodation space must be made as low as possible, taking into account the ship's stability (rising center of gravity) and air draft. Therefore, it may be possible to make the accommodation space structure T-shaped when viewed from the front.

[0003] A prior example of a ship accommodation area having a T-shape when viewed from the front is disclosed in, for example, JP 2018-62313 A. The disclosure of JP 2018-62313 A relates to an invention entitled "Ship accommodation area structure and cargo carrier," and in the problem to be solved by the invention "to provide a ship accommodation area structure and cargo carrier that can effectively increase accommodation space while minimizing the impact on the stability of the hull, air draft, cargo load, and equipment such as lifeboats" (see paragraph Nangou) 0004 of the specification of the same publication), it is described as "a ship accommodation area structure having a hull with a pair of sideboards provided on both sides in the ship width direction and an upper deck connecting these sideboards, a hold extending from the front to the rear in the bow-stern direction for loading cargo, and an engine room located aft of the hold in the bow-stern direction, The above-mentioned disclosure provides a "ship accommodation structure comprising: a lower deckhouse located above the machinery space on the upper deck, away from the pair of shipboard sides in the ship's width direction and on the inside; and an upper deckhouse located above the lower deckhouse and protruding outward in the ship's width direction from the lower deckhouse; and an outfitting mounting section for mounting outfitting, located between the shipboard sides and the lower deckhouse on the upper deck and below the portion of the upper deckhouse that protrudes outward in the ship's width direction from the lower deckhouse" (see the description of claim 1 of the same publication, etc.), which has the effect of "effectively increasing the amount of accommodation while minimizing the impact on the hull's stability, air draft, cargo carrying capacity, and equipment such as lifeboats" (see paragraph 0012 of the specification of the same publication).

[0004] FIG. 3 is a front view showing a configuration of a superstructure of a cargo carrier in one embodiment of the disclosed invention attached as FIG. 3 in JP 2018-62313 A. In FIG. 3, reference numeral 101 denotes a cargo carrier, 110 denotes a hull, 110s denotes a side, 115 denotes an upper deck, 120 denotes a superstructure, 121 denotes a bridge, 122 denotes a bridge wing, 122t denotes a tip portion, 123 denotes a deckhouse portion, 124 is an equipment mounting section, 125 is a lower deck house, 125w is a side wall section, 126 is an upper deck house, 126h is an overhang section, 126w is a side wall section, 129 is a support pillar, 1100 is a cabin, RB is a lifeboat, and W is a ship's width direction (in order to clarify that the symbols are prior art, the applicant of the present application has changed the symbols from two digits to three digits and from three digits to four digits in the explanation).

[0005] However, the vessel disclosed in JP 2018-62313 A states, "...having a lower deckhouse located away on the inside in the width direction of the vessel and an upper deckhouse that protrudes outward in the width direction of the vessel than the lower deckhouse, the vessel has a T-shaped accommodation area when viewed from the front, and rescue boats and other fittings are mounted below the overhanging part that protrudes in the width direction of the vessel. Since fittings such as rescue boats generally have an opening space of about 6m in width and 8m in height, there is a problem with the strength of the support of the overhanging part that protrudes in the width direction of the T-shaped accommodation area." Therefore, the inventors of the present application have devised a ship's accommodation support structure in which a fuel tank is placed below the overhanging portion that protrudes in the width direction of the T-shaped accommodation shape, thereby increasing the strength of the overhanging portion that protrudes in the width direction of the T-shaped accommodation shape.

[0006] Incidentally, an example of arranging a fuel tank on the upper deck of a ship is disclosed in, for example, Japanese Patent No. 6780813. The disclosure of Japanese Patent No. 6780813 relates to an invention titled "Ship," and in its problem to be solved by the invention, which aims to "provide a ship capable of realizing a tank arrangement that minimizes the area requiring heat insulation treatment in a ship compartment, even when a liquefied gas fuel tank is arranged on the exposed deck at the stern and around the accommodation area, service space, control room, evacuation passage, and machinery room" (see paragraph number 0006 of the specification of the same publication), it provides a ship having a liquefied gas fuel tank, in which the liquefied gas fuel tank is arranged on the upper deck or on the exposed deck above the upper deck and behind a superstructure arranged on the stern side, and the range in which a tank structure consisting of a tank body and a tank dome of the liquefied gas fuel tank is arranged is within a range in which an exposed portion of the tank structure is not visible when the superstructure is viewed from the front, and the exposed portion of the tank structure is not visible when the superstructure is viewed from the front, The configuration has the following effects: "a heat barrier, not a tank cover covering the tank structure, is provided between the exposed portion of the tank structure and a surface of the upper structure facing the exposed portion of the tank structure that requires heat insulation, and the heat barrier that has been heat-insulated blocks radiant heat from the exposed portion of the tank structure to the surface that requires heat insulation" (see claim 1 of the same publication, etc.), "the radiant heat from the exposed portion of the tank structure of the liquefied gas fuel tank can be blocked by the heat-insulated surface that requires heat insulation or by the heat barrier that has been heat-insulated, thereby increasing the degree of freedom in the layout of the upper structure having a surface that requires heat insulation, and the heat insulation treatment or heat barrier of the surface that requires heat insulation can protect living areas, service spaces, evacuation passages, control rooms, machine rooms, etc. from fires and the like that may result from accidents with the liquefied gas fuel tank" (see paragraph 0016 of the specification of the same publication).

[0007] However, the fuel tank on the upper deck disclosed in Patent No. 6780813 is designed not to obstruct the forward visibility of the ship's accommodation space, by stating that "the tank structure consisting of the tank body and tank dome is located within a range in which the exposed part of the tank structure is not visible when the superstructure is viewed from the front" (see claim 1 of the same patent). Therefore, as described above, the inventors of the present application have devised a ship's accommodation support structure in which the marine fuel tank is positioned below the overhanging portion that protrudes in the width direction of the T-shaped accommodation shape, thereby ensuring forward visibility from the accommodation area, while at the same time making the height support for the overhanging portion that protrudes in the width direction of the T-shaped accommodation shape as short as possible and placing a support column or support wall between them, thereby increasing the strength of the overhanging overhanging portion of the T-shaped accommodation area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment for carrying out a support structure for an accommodation space of a ship according to the present invention will be described in detail with reference to the drawings. EXAMPLES

[0014] Figures 1 and 2 show a first embodiment of a support structure for accommodation space of a ship according to the present invention, in which Figure 1 is a front view of the support structure for accommodation space of a ship according to the first embodiment as seen from the front of the ship, and Figure 2 is a side view of the structure 1. In Figures 1 and 2, reference numeral 1 denotes the support structure for accommodation space of a ship according to the first embodiment, 2 denotes the hull, 3 denotes a T-shaped accommodation space, 3a and 3b denote the transverse extensions of the T-shaped accommodation space 3, 4, 4a and 4b denote fuel tanks, 5a (5a1, 5a2 and 5a3), 5b, 5c and 5d denote support columns serving as support members, 6a and 6b denote gangway ladders, 7a and 7b denote void spaces, 8 denotes an engine room, 9 denotes a cargo space, 10 denotes a bottom fuel tank, 11 denotes a propeller, 12 denotes a rudder, and 13 denotes a chimney.

[0015] In addition, in Figures 1 and 2, symbols la and lb indicate the width-wise spacing between the T-shaped accommodation area 3 and the fuel tanks 4a and 4b, and h, ha, and hb indicate the height-wise spacing between the lower ends of the protruding portions 3a and 3b of the T-shaped accommodation area 3 and the fuel tanks 4a and 4b. As shown in FIG. 1, the accommodation support structure 1 of the ship in this embodiment 1 has an accommodation 3 on the upper deck of the ship that is T-shaped when viewed from the front, with fuel tanks 4a, 4b arranged on both sides below the overhangs of the transverse protrusions 3a, 3b, and support members 5 (support columns 5a (5a1, 5a2, 5a3), 5b, 5c, 5d) provided between the fuel tanks 4a, 4b and the transverse protrusions 3a, 3b of the T-shaped accommodation 3, which ensures the strength of the transverse protrusions 3a, 3b and, ultimately, the rigidity of the T-shaped accommodation 3 itself, and makes it possible to suppress an increase in weight due to reinforcement for ensuring rigidity and a rise in the center of gravity due to the increased weight of the reinforcement.

[0016] As shown in Figure 1, the accommodation support structure 1 of the ship in this embodiment 1 has an accommodation 3 on the upper deck of the ship, which has a T-shaped accommodation structure that is T-shaped when viewed from the front of the ship, and fuel tanks 4a, 4b are arranged on both sides of the T-shaped accommodation 3 under the overhangs of the transverse protruding portions 3a, 3b of the T-shaped accommodation 3, with transverse separation spaces la, lb and heightwise separation spaces h, ha, hb between them. In order to support the transverse protruding portions 3a, 3b of the T-shaped accommodation space 3 within the vertical clearance spaces h, ha, hb on the peripheral walls of the fuel tanks 4a, 4b, a plurality of support pillars (in the accommodation space support structure 1 of the ship according to this embodiment 1, a total of 12 support pillars 5a (5a1, 5a2, 5a3), 5b, 5c, 5d) are arranged at the four corners and two at the center of the long sides of the fuel tanks 4a, 4b as shown in FIG. 1).

[0017] As a result, in the accommodation space support structure 1 of the ship according to this embodiment 1, the accommodation space 3 on the upper deck of the ship is made T-shaped when viewed from the front, so that visibility to the front of the ship can be secured and there is no hindrance to ship operation. Furthermore, on both sides of the lower part of the T-shaped accommodation space 3, as shown in FIG. 1, there are provided widthwise separation spaces la, lb between the fuel tanks 4a, 4b arranged on both sides, and heightwise separation spaces h, ha, hb between the lower ends of the protruding parts 3a, 3b of the T-shaped accommodation space 3 and the fuel tanks 4a, 4b, so that the impact on the T-shaped accommodation space 3 can be reduced even if the fuel tanks 4a, 4b are damaged.

[0018] In addition, the fuel tanks 4a, 4b arranged on both sides are arranged at a specified distance between the gangway ladders 6a, 6b that must be provided on the ship, as shown in Figure 1, so there is no impact on boarding and disembarking the ship while it is at anchor. In the accommodation support structure 1 of the ship according to this embodiment 1, the widthwise separation spaces la, lb, the heightwise separation spaces h, ha, hb, and the separation distances between the gangway 6a, 6b can be set to appropriate distances depending on the size of the ship and the need for fuel storage in the fuel tanks 4a, 4b, etc., and in the accommodation support structure 1 of the ship according to this embodiment 1, the support members for the heightwise separation spaces h, ha, hb between the fuel tanks 4a, 4b and the lower ends of the projections 3a, 3b are support columns 5a (5a1, 5a2, 5a3), 5b, 5c, 5d, but this is not limited to a pillar structure made of column material and may be a flat plate structure.

[0019] Furthermore, as shown in Figures 1 and 2, in addition to the fuel tank 10 that is usually placed at the bottom of the ship, fuel tanks 4a and 4b are mounted on the upper deck, so that an increased amount of fuel can be carried. Note that the fuel may be heavy oil or methanol fuel as in the past, and the outer surfaces of the fuel tanks 4a and 4b may be painted with a heat insulating paint in order to suppress the volatilization of the fuel (suppressing the danger associated with the vaporization and release of the fuel).

[0020] In addition, in order to install the fuel tanks 4a, 4b under the overhangs of the overhanging parts 3a, 3b of the T-shaped accommodation space 3, a rectangular fuel tank of a predetermined shape may be manufactured internally, and the fuel tanks 4a, 4b may first be installed on the upper deck under the overhangs of the overhanging parts 3a, 3b of the T-shaped accommodation space 3 at the installation positions of the fuel tanks 4a, 4b, and then the accommodation space 3 with the support members 5a (5a1, 5a2, 5a3), 5b, 5c, 5d may be mounted between the fuel tanks 4a, 4b. The fittings around the living space are arranged in the usual way, and a new structure has been created in which the fuel tanks 4a, 4b located on either side of the living space 3 are used to support the living space 3.If there were no supporting members, the lower parts of the protruding parts 3a, 3b of the T-shaped living space 3 would have a cantilever structure, which would pose strength problems and require reinforcement to correct this, which would mean that the reinforcement weight would have to be located in a high position.However, with the new structure described above, there is no need for reinforcement weight in a high position, which is advantageous in terms of ship stability.
