Abstract: An offshore oil production platform comprising one section disposed on the sea bed and another section connected to the one section and projecting up above the sea surface. The one section consists of a plurality of prefabricated units comprising at least one tank divided into a plurality of compartments and having a peripheral wall the thickness of which is not adapted to withstand full water pressure with the tank empty in the submerged state, and at least one compartment in the tank has a peripherial wall the thickness of which is adapted to withstand full water pressure when empty in the submerged state.
