Undersea Station Draft No.4: Hangar

© CalamarPark.comSo far the final draft follows the hangar shape. Having a look at the evaluation list in the ‘Structural Shape‘ chapter it seems like the ideal shape for the undersea station.

Because of the sand used as variable ballast and the space under the station the structure is easily removable by just releasing the sand. No harmful materials or items would be left behind which serves the ecological idea.

Being a stretched shape the living space has the targeted ‘human size‘ and may be used as an environment for ‘reasonable living’.

Modularity

The two sides of the station are cut at an angle. Attaching identical modules will bring the structure into the shape of a ring. If the angle on one side of the module is 22,5 degrees the total angle between two modules will be 45 degrees. Like this it would need 7 modules to create an open ring or 8 to complete the whole ring. By attaching each module the total structure would be strengthened:

Each module contains a corridor that allows to move from one module to the other without passing every single room. Therefore the modules can serve educational, private or scientific purposes which might attract a wider range of potential investors.

Because of the U-shaped ballast tanks the structure would maintain a stable position during the landing procedure.

The structure will be protected against drifts by ‘drift shields‘. They cover the space under the structure and their angle is adjustable.

The weakest part of the structure will be the seals around the portholes while the ceiling will be reinforced. In case of water ingress the area between the breach and the ceiling will serve as an emergency safety zone. In any case this zone will stay with air. Electronics and life-support systems are mounted in this area and there is no hull penetration (for cables or pipes) over the last possible predetermined breaking point, the upper porthole frame.

The shape is very attractive especially if other modules are attached and the open/closed ring is maintained.
