Abstract

A basement (1) for locating on the sea bed (11) comprises a floatable and submersible structure having tanks subjected to the ambient hydrostatic pressure acting as buoancy/ballast compartments. The basement (1) can preferably be constructed as a hybride structure consisting of an upper (2) and a lower (3) plate of concrete with the tanks (6) of steel located between the plates.
