Partially submerged floating platform

Claim 1

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.
