In addition, the local fire extinguishing device 25 for Class A engine area in this embodiment is, for example, a water fire extinguishing device, but the type of the local fire extinguishing device 25 for Class A engine area is not limited.

[0030] The ventilation device 26 for cargo equipment room is a device that is located inside or outside the cargo equipment room 53 and replaces the air inside the cargo equipment room 53 through a ventilation opening during normal times for ventilation, and cuts off the outflow of the gas inside the cargo equipment room 53 to promote fire extinguishing in the event of a fire. Therefore, the ventilation device 26 for cargo equipment room is a fire control device that protects the equipment located in the stern area 12. In addition, the ventilation device 26 for cargo equipment room in this embodiment is, for example, an exhaust fan, but the type of the ventilation device 26 for cargo equipment room is not limited.

[0031] The ventilation device 27 for Class A engine area is a device that is located inside or outside the Class A engine area 52 and cuts off the supply of air into the Class A engine area 52 in the event of a fire to promote fire extinguishing. Therefore, the ventilation device 27 for Class A engine area is a fire control device that protects the equipment located in the stern area 12. In addition, the ventilation device 27 for Class A engine area in this embodiment is, for example, an air supply fan, but the type of the ventilation device 27 for Class A engine area is not limited.

[0032] The ventilation device 28 for living area is a device that is located inside or outside the living area 51 and cuts off the supply of air into the living area 51 in the event of a fire or when gas is detected inside the living area 51 to promote fire extinguishing. Therefore, the ventilation device 28 for living area is a fire control device that protects the equipment located in the bow area 11. In addition, the ventilation device 28 for living area in this embodiment is, for example, an air supply fan, but the type of the ventilation device 28 for living area is not limited.

[0033] <The first fire control location>

[0034] The first fire control location 30 is a control location capable of operating at least a part of the fire control devices 20 to 28. In the first fire control location 30 of the present embodiment, all of the above-mentioned fire control devices 20 to 28 can be operated. As Figure 2 shown, operation devices 70 to 78 corresponding to the fire control devices 20 to 28 are provided in the first fire control location 30. By an operator operating each of the operation devices 70 to 78, a control signal can be sent from each of the operation devices 70 to 78 to the corresponding fire control device 20 to 28 to operate each of the fire control devices 20 to 28.

[0035] As Figure 1 shown, the first fire control location 30 of the present embodiment is located in the bow area 11, and more specifically, within the living area 51.

[0036] <Second Fire Control Location>

[0037] The second fire control location 40 is a control location capable of operating at least a part of the fire control devices 20 to 28. In the second fire control location 40 of the present embodiment, the fire control devices 20 to 27 other than the ventilation device 28 for the living area among the above-mentioned fire control devices 20 to 28 can be operated. As Figure 2 shown, operation devices 70 to 77 corresponding to the fire control devices 20 to 27 are provided in the second fire control location 40. By an operator operating each of the operation devices 70 to 77, a control signal can be sent from each of the operation devices 70 to 77 to the corresponding fire control device 20 to 27 to operate each of the fire control devices 20 to 27.

[0038] As Figure 1 shown, the second fire control location 40 of the present embodiment is located in the stern area 12, and more specifically, within the upper structure 54 of the stern.

[0039] The above is the description of the ship 100 of the embodiment. As described above, in the present embodiment, the fire control devices 20 to 27 other than the ventilation device 28 for the living area among the fire control devices 20 to 28 can be operated from either the first fire control location 30 or the second fire control location 40. That is, according to the present embodiment, the fire control devices 20 to 27 can be operated from multiple fire control locations 30 and 40. Therefore, as long as the operator goes to the nearer one of the fire control locations 30 and 40 after recognizing the occurrence of a fire, the time from when the operator confirms the occurrence of the fire until reaching the fire control locations 30 and 40 can be shortened. As a result, the fire extinguishing operation can be started promptly.

[0040] In addition, in the second fire control station 40 located in the stern area 12, the ventilation device 28 for the living quarters among the above-described fire control devices 20 to 28, that is, the fire control device that only targets the equipment located in the bow area 11, cannot be operated. Only the fire control devices 20 to 27 that include the equipment located in the stern area 12 in the protection target can be operated. Assuming a fire breaks out in the bow area 11, the operator who confirms the occurrence of the fire does not go to the second fire control station 40 located in the stern area 12, but goes to the first fire control station 30 located in the bow area 11. Therefore, even if the second fire control station 40 is configured to only be able to operate the fire control devices 20 to 27 that include the equipment located in the stern area 12 in the protection target, the start of the fire extinguishing operation will not be delayed.

[0041] Conversely, by configuring the second fire control station 40 not to be able to operate all of the fire control devices 20 to 28, but to be able to operate only the fire control devices 20 to 27 that include the equipment located in the stern area 12 in the protection target, the second fire control station 40 can be simplified. In addition, in the second fire control station 40, it may not be configured to only be able to operate the fire control devices 20 to 27 that include the equipment located in the stern area 12 in the protection target, but may be configured to only be able to operate the fire control devices that include at least the equipment located in the stern area 12 or the central area 13 in the protection target. In this case, the second fire control station 40 can also be simplified.

[0042] (Modification example)

[0043] In the above-described embodiment, the first fire control station 30 is located in the bow area 11, and the second fire control station 40 is located in the stern area 12. However, it may also be that the first fire control station 30 is located in any of the three areas 11 to 13, and the second fire control station 40 is located in an area other than the area where the first fire control station 30 is located among the three areas 11 to 13. For example, it may also be that the first fire control station 30 is located in the stern area 12, and the second fire control station 40 is located in the bow area 11. In this case, the second fire control station 40 may also be able to operate only the fire control devices that include at least the equipment located in the bow area 11 or the central area 13 in the protection target.

[0044] In addition, the above-described ship 100 has the first fire control station 30 and the second fire control station 40, but in addition to these fire control stations, it may also have a third fire control station. In this case, each fire control station may also be located in a different area among the above-described three areas 11 to 13.
