Cargo tank 10 is located in the cargo area 12, which includes the central portion of the hull 11 in the forward and aft direction. However, the location of cargo tank 10 is not limited. Furthermore, depending on the type of floating structure 100, the floating structure 100 may not have cargo tank 10.
[0024] <Cabin>
[0025] The engine room 20 is a room that houses the engine 21. In this embodiment, the engine 21 is the propulsion engine for the hull 11. The structure of the engine 21 is not limited; it can be a steam generating device that produces steam to drive a steam turbine connected to the propeller 22, or a gas engine that uses liquefied petroleum gas (LPG) as fuel, a diesel engine that uses heavy oil as fuel, or a dual-fuel engine that uses both LPG and heavy oil as fuel. Furthermore, the engine 21 can also be a power generation device that generates electricity by rotating a generator using any of the fuel oil engine, gas engine, or dual-fuel engine, or by generating electricity using a fuel cell. In this embodiment, the engine room 20 is located in the stern region 13 of the hull 11, further aft of the cargo area 12. However, the location of the engine room 20 is not limited.
[0026] Figure 2 This is a horizontal sectional view of the floating structure 100 at its height position of the internal passage 40, which will be described later. Figure 2 In the middle, the area near the center in the front-rear direction of the floating structure 100 is omitted. Figures 3 to 6 Similarly). Figure 2 As shown, the engine compartment 20 includes a storage area 23 and a control area 24. The storage area 23 is for housing the engine 21. Within the storage area 23, the noise emitted by the engine 21 is very loud, so there is a possibility that the operator may experience stress when passing through the storage area 23.
[0027] On the other hand, control partition 24 is a partition for operators to control and / or monitor engine 21. An operation panel for operating engine 21 is provided in control partition 24. Furthermore, in this embodiment, control partition 24 is located in the front portion near the center in the width direction of the engine compartment 20. However, the location of control partition 24 is not limited to the above-described location. In addition, control partition 24 is isolated from storage partition 23. Specifically, control partition 24 is divided by walls or the like and separated from storage partition 23. Noise generated by engine 21 is blocked by walls or the like and is not easily transmitted into control partition 24. Furthermore, control partition 24 can also be configured such that operators can move between control partition 24 and storage partition 23 via an entrance or exit with a door.
[0028] <Residential Area>
[0029] The living area 30 is an area where ship passengers, including workers, live or conduct business. In addition to the living space for ship passengers, the living area 30 also includes business areas for operating cargo equipment, equipment rooms, warehouses, steps, passageways, meeting rooms, and reception rooms. In this embodiment, the living area 30 is located in the bow area 14 of the hull 11, forward of the cargo area 12. However, the location of the living area 30 is not limited. Furthermore, the living area 30 in this embodiment includes an upper section 31 located above the upper deck 15 and a lower section 32 located below the upper deck 15. The upper section 31 and the lower section 32 are connected by steps or the like, allowing workers to move between the upper section 31 and the lower section 32 via steps or the like.
[0030] <Internal Pathway>
[0031] Internal passageway 40 is a passageway accessible to workers, located on the hull 11 below the upper deck 15. For example... Figure 1 As shown, the internal passageway 40 of this embodiment extends from the bow area 14 to the stern area 13 through the cargo area 12, connecting the lower level 32 of the living quarters 30 to the engine room 20. Therefore, workers can move from the living quarters 30 to the engine room 20 without leaving the ship via the internal passageway 40, and can also move from the engine room 20 to the living quarters 30. The details of the internal passageway 40 will be described below.
[0032] (Details of the internal pathways)
[0033] Next, the details of the internal passage 40 will be explained. For example... Figure 2 As shown, the internal passage 40 of this embodiment includes a starboard passage 50, a port passage 60, and a connecting passage 70. These passages will be described in turn below.
[0034] <Starboard access>
[0035] The starboard passage 50 is located below the upper deck 15 and extends along the starboard side of the hull 11. Specifically, the starboard passage 50 is located at the starboard end of the hull 11 and extends in the fore-and-aft direction. In this embodiment, the starboard passage 50 includes a straight section 51, a forward expansion section 52, and an aft expansion section 53. The straight section 51 is located at the center of the starboard passage 50 in the fore-and-aft direction and has a constant width. The forward expansion section 52 is located at the front end of the starboard passage 50 and has a larger width than the straight section 51, increasing in size as it approaches the living quarters 30. The aft expansion section 53 is located at the rear end of the starboard passage 50 and has a larger width than the straight section 51, increasing in size as it approaches the engine room 20. However, the shape of the starboard passage 50 is not limited to the above-described shape.
[0036] The starboard passageway 50 has a living area entrance 54 at its forward end, which connects to the lower level 32 of the living area 30. This allows workers to move between the living area 30 and the starboard passageway 50 via the living area entrance 54. A living area entrance door 55 is provided at the living area entrance 54 for opening and closing. Furthermore, the starboard passageway 50 has a storage compartment entrance 56 at its rear end, which connects to the storage compartment 23 of the engine room 20. This allows workers to move between the storage compartment 23 and the starboard passageway 50 via the storage compartment entrance 56. A storage compartment entrance door 57 is provided at the storage compartment entrance 56 for opening and closing.
[0037] <Port side access>
[0038] The port side passage 60 is located below the upper deck 15 and extends along the port side of the hull 11. Specifically, the port side passage 60 is located at the port end of the hull 11 and extends in the fore-and-aft direction. In this embodiment, the port side passage 60 includes a straight section 61, a forward expansion section 62, and an aft expansion section 63. The straight section 61 is located at the center of the port side passage 60 in the fore-and-aft direction and has a constant width. The forward expansion section 62 is located at the front end of the port side passage 60 and has a larger width than the straight section 61, increasing in size as it approaches the living quarters 30. The aft expansion section 63 is located at the rear end of the port side passage 60 and has a larger width than the straight section 61, increasing in size as it approaches the engine room 20. However, the shape of the port side passage 60 is not limited to the above-described shape.
[0039] The port side passageway 60 has a living area entrance 64 at its forward end, which connects to the lower level 32 of the living area 30. This allows workers to move between the living area 30 and the port side passageway 60 via the living area entrance 64. A living area entrance door 65 is provided at the living area entrance 64 for opening and closing. Furthermore, the port side passageway 60 has a storage compartment entrance 66 at its rear end, which connects to the storage compartment 23 of the engine room 20. This allows workers to move between the storage compartment 23 and the port side passageway 60 via the storage compartment entrance 66. A storage compartment entrance door 67 is provided at the storage compartment entrance 66 for opening and closing.
[0040] <Connection Path>
[0041] The connecting passage 70 connects the starboard passage 50 and the port passage 60. The connecting passage 70 extends along its width. Its starboard end connects to the starboard passage 50, and its port end connects to the port passage 60. Therefore, workers can travel between the starboard passage 50 and the port passage 60 via the connecting passage 70. Furthermore, when viewed from the engine room 20, the connecting passage 70 is located on the living quarters side 30, that is, forward of the engine room 20, and adjacent to the engine room 20.
[0042] The connecting passage 70 in this embodiment has a partition wall 71. The partition wall 71 is a wall that divides the connecting passage 70 into left and right sections. A partition door 72 is provided on the partition wall 71. An operator can move between the section on the right side of the connecting passage 70 and the section on the left side of the connecting passage 70 via the partition door 72. The partition wall 71 can be, for example, a fireproof wall or a fireproof roller shutter. Alternatively, the partition wall 71 may not always separate the connecting passage 70, but only separate the connecting passage 70 in an emergency.
[0043] Thus, since the connecting passage 70 of this embodiment has a partition wall 71, for example, even if a fire occurs in the starboard passage 50, it is possible to prevent the flames and smoke associated with the fire from reaching the port passage 60, and even if a fire occurs in the port passage 60, it is possible to prevent the flames and smoke associated with the fire from reaching the starboard passage 50.
[0044] Furthermore, the connection passage 70 of this embodiment has a control partition opening 73, through which it connects to the control partition 24. Therefore, the operator can move between the connection passage 70 and the control partition 24 via the control partition opening 73. Thus, the operator can enter and exit the control partition 24 from the internal passage 40 without passing through the storage partition 23, and therefore can enter and exit the control partition 24 of the engine compartment 20 without feeling pressured by noise from the engine 21. Additionally, the operator does not pass through the storage partition 23, which is prone to overheating, thus allowing safe access to the control partition 24 of the engine compartment 20. Furthermore, since the operator does not pass through the storage partition 23, the control partition 24 can be accessed quickly. Additionally, a control partition opening door 74 is provided at the control partition opening 73 to open and close the control partition opening 73.
[0045] The internal passageway 40 can also be configured to be accessible from the upper deck 15 via steps or the like. Furthermore, the floor level of the internal passageway 40 can be different from the floor level of the control zone 24. In this case, the internal passageway 40 can also have steps leading from the ground to the control zone opening 73, and the control zone 24 can also have steps leading from the ground to the control zone opening 73.
[0046] <About Each Department>
[0047] As described above, the internal passageway 40 of this embodiment includes living area doors 55 and 65, storage area doors 57 and 67, partition doors 72, and control area doors 74. The living area doors 55 and 65, storage area doors 57 and 67, partition doors 72, and control area doors 74 are collectively referred to as "internal passageway doors." In this embodiment, all internal passageway doors are configured to be lockable. Therefore, for example, even if pirates invade the floating structure 100, passengers can escape into the engine room 20 and lock the internal passageway doors to prevent harm from the pirates. However, it is also possible to configure only a portion of the internal passageway doors to be lockable.
[0048] Furthermore, in this embodiment, the rightmost door of the internal passageway is located to the left of the straight section 51 of the starboard passageway 50. Additionally, the leftmost door of the internal passageway is located to the right of the straight section 61 of the port passageway 60. With this configuration of the internal passageway doors, even if the hull 11 tilts, as long as the tilt angle is within a specified range, water will not enter the engine room 20 and living quarters 30 through the internal passageway doors. Therefore, the internal passageway doors can be inexpensive, non-watertight doors, thus reducing the manufacturing cost of the floating structure 100. Alternatively, the internal passageway 40 may also have doors other than those included in the aforementioned internal passageway doors. Even in this case, by positioning the rightmost door of the internal passageway 40 to the left of the straight section 51 of the starboard passageway 50 and the leftmost door to the right of the straight section 61 of the port passageway 60, the manufacturing cost of the floating structure 100 can also be reduced.
[0049] (Variation Example 1)
[0050] The floating structure 100 has been described above, but its structure is not limited to the above-described structure. For example, in Figure 2 In the middle, the connecting path 70 is connected to the control partition 24 via the control partition port 73, but if Figure 3 As shown, connection path 70 can also be connected to control partition 24 via control partition port 73 and transit partition 25. Transit partition 25, as mentioned here, is a partition isolated from storage partition 23 and connected to control partition 24. Transit partition 25 can, for example, be a power distribution panel partition equipped with a power distribution panel. Even... Figure 3 With the structure shown, operators can enter and exit the control section 24 via the internal passageway 40 without passing through the storage section 23, thus allowing them to enter and exit the control section 24 of the engine compartment 20 without feeling the pressure caused by the noise from the engine 21. In addition, the transfer section 25 can also be configured so that operators can travel between the storage section 23 via an entrance or exit with a door.
[0051] (Variation Example 2)
[0052] In addition, such as Figure 4 As shown, the control zone 73 may also include a right control zone 75 located to the right of the partition wall 71 and a left control zone 76 located to the left of the partition wall 71. With this structure, for example, even if a fire occurs in the internal passageway 40, operators can enter and exit the control zone 24 without passing through areas more severely affected by the fire. Additionally, a lockable right control zone door 77 for opening and closing the right control zone 75 may be provided, and a lockable left control zone door 78 for opening and closing the left control zone 76 may be provided.
[0053] (Variation Example 3)
[0054] In addition, such as Figure 5 As shown, when the control compartment 24 is located at the port end of the engine room 20, the control compartment opening 73 can also be located in the port passageway 60. In this case, the connecting passageway 70 can be omitted from the internal passageway 40. Additionally, although not shown, when the control compartment 24 is located at the starboard end, the control compartment opening 73 can also be located in the starboard passageway 50.
[0055] (Variation Example 4)
[0056] In addition, such as Figure 6 As shown, in addition to the connecting passageway 70 adjacent to the engine room 20, the internal passageway 40 may also have a connecting passageway 80 adjacent to the living area 30. The connecting passageway 80 adjacent to the living area 30 connects to the starboard passageway 50 and the port passageway 60, and further connects the starboard passageway 50 and the port passageway 60. Moreover, as... Figure 6 As shown, the connecting passage 80 may also have a residential area entrance 81, and is connected to the lower level 32 of the residential area 30 via this residential area entrance 81. According to Figure 6 The structure shown increases the degree of freedom for accessing the residential area 30 from the internal passage 40. Additionally, a lockable entrance door 82 can be installed at the entrance 81 to open and close the entrance.
