Abstract
A floating platform has a polygonal, submerged floating body constructed from concentric pipe sections whereby the space between each two concentric pipes is compartmentized and serves as storage facility as well as ballast tanks. Columns also constructed as upright concentric pipes extend from the submerged float and carry platform defining and establishing frame which carries e.g. a drilling derrick. The interior spaces of all inner pipes serve as transport path, a closed one being provided in the main float and elevator(s) as well as pump-up paths for liquid loads are provided in the columns.
Claims5
Partially submerged floating platform having a plurality of vertical columns constructed from concentric pipes with compartmentization of the space between respective inner and outer pipes;
- a frame interconnecting the columns above the sea level and providing for and establishing a working area of the platform, the improvement comprising:
- a submerged main floating body of near rotational symmetry and having predominantly horizontal extension, the body being constructed from sections of concentric pipes which extend around a vertical axis in near-annular fashion, the space between respective inner and outer pipe sections being compartmentized, the columns being connected and extending upright from the main body but projecting above sea level;
- the inner pipe of the body being hollow and constructed as passage way for moving of loads;
- individual ballast bodies movably disposed in the inner pipe and moving along the passage way to change the effective ballast in relation to the center axis of the platform;
- the inner pipe of at least one column constructed for transporting loads from the submerged body to the frame.
