In FIG. 5 or FIG. 7, reference numerals 37 and 38 denote emergency exits provided for each of the guest rooms 6a, 6b, and 6c, and communicate with the emergency evacuation routes 14 and 19, respectively. In each of the guest rooms 6a, 6b and 6c, a viewing window 39 (preferably a round window) is provided.

In FIG. 6, the passenger cabin 6a, 6b and 6c are vertically separated by an upper cabin deck 40, a first cabin deck 41, a second cabin deck 42 and a third cabin deck 43. The partition of the escalator 31 is divided by a partition wall 44, and the partition wall 44 is provided with a plurality of entrances and exits 45 to each cabin deck for each floor. These entrances 45 are configured as openable watertight doors.

In FIG. 7, a seabed search lamp chamber 46 is provided near the center of the buoyancy tank 8, for example. The searchlight 47 installed in the seabed searchlight chamber 46 can project a water depth of 100 meters or more. In the seabed searchlight room 46, a seabed photographing machine (not shown) can be installed.

FIG. 8 shows an example of construction of the viewing window 39. Special construction block 48 in which viewing windows 39 are arranged
Is mounted and fixed in the mounting area 49 in FIG. Then, the viewing window 39 is constructed as shown in FIG.

The catamaran-type underwater sightseeing ship according to the present invention is a catamaran and therefore has extremely high navigation safety. In particular, since the rolling damping tank 7 is provided on both sides, the hull oscillating cycle by the fixed ballast tank 10 at the lower part of the hull is reduced, and the buoyancy is increased. The rolling damping tank 7 projects from the side of the ship, so that
In addition to being able to cover the part, the security of the part can be enhanced, and in addition, it is possible to effectively prevent a floating object or the like from directly colliding with the passenger hold 6. Further, the water pressure applied to the passenger hold 6 is divided or reduced, but during the underwater sightseeing, the passenger hold 6 is below the water surface, and the rolling damping tanks 7 on both sides exert a mitigation action against any external impact. Also, since there is a rolling damping tank 7 on both sides,
It is possible to mitigate the direct hit of waves on the deck living room.

The arrangement of the ballast tanks 13, 18 at the bow and stern suppresses a decrease in the center of gravity of the ship due to the fixed ballast tank 10 at the lower part of the hull, and enhances the safety of the hull. By the fixed ballast tank 10 in the lower part of the hull, almost half of the predetermined draft (about 5 meters) can be secured. The seawater ballast including the rolling damping tank 7 can be lowered to a predetermined draft (about 5 meters), and the maximum draft can be 10 meters in cooperation with the fixed ballast. With respect to the hull inclination in an emergency, the seawater ballast tanks 13 and 18 at the stern of the stern are divided into right and left, so that the hull balance can be adjusted. The seawater ballast is drained at the time of taking off and landing, and only the fixed ballast by the fixed ballast tank 10 is used. Seawater ballast injection and drainage can be remotely controlled in the wheelhouse. Each seawater ballast tank will be equipped with a manual pouring and draining device along with remote pouring and draining.

If the passenger hold 6 is flooded, buoyancy is compensated for by the buoyancy tank 8 at the center of the hull, so that security in an emergency can be improved. Further, the flooded water is immediately dropped into the emergency water storage tank 9 at the lower part of the hull through the outlet 6d (see FIG. 3), and therefore, even if the flooding occurs, the water may be stored in the passenger hold 6. There is no.

Emergency evacuation routes 14, 19 at bow and stern
To ensure passenger safety in an emergency. In addition, the partition wall 35 of each guest room deck escalator 31
Is watertight and provides an evacuation site for passengers in an emergency.

A shutter 25 is provided inside and outside the passenger hold 6.
The security of the hull in an emergency can be enhanced by providing the emergency shutter device including the. The emergency shutter 25 does not cover the entire passenger compartment from the front to the rear, but is preferably divided into about five sections. For example, when there is a risk of contact with an underwater obstacle during underwater sightseeing, closing the emergency shutter 25 can prevent a direct contact accident with the passenger hold 6. The emergency shutter 25 is preferably made of a material that is watertight and does not rust.

It is to be noted that a monitoring device capable of grasping the entire interior of all the passenger cabin may be provided in the bridge, and the opening and closing operation of the emergency shutter 25 may be performed on the bridge. In addition, the structure of the emergency shutter device is applicable to a steel heart type of a general cargo ship.

The underwater glass of the viewing window 39 in the passenger hold 6 is a specially processed pressure-resistant glass, so that danger can be avoided. The window frame of each string should be made of a material that does not rust. The underwater state can be observed through the viewing window 39. In this case, the seabed exploration cruising at a depth of 100 meters or more can be realized by using the automatic and manual search lights 34 and 47 capable of projecting the depth of 100 meters or more. .

In the above embodiment, an underwater video repeater is preferably installed in the steering room. Further, the air pressure in the passenger hold 6 is always kept constant to the external water pressure by the automatic pressure adjusting device. Further, a protective device may be provided for the pair of screws.

[0026]

As described above, according to the present invention, in this type of catamaran underwater sightseeing boat, extremely high safety can be ensured, and safe and stable navigation can be performed. As a result, comfortable seabed exploration cruising is realized and is expected to greatly contribute to the development of ocean exploration.
