Abstract

An oscillating ocean platform, designed especially for use at great depths, comprises base means 16 which rests on or are fixed to the sea bed 18, a rigid upper part 2 which supports the bridge 1 and is associated with a buoyancy reserve 7, and a flexible lower part 3, which comprises a structure of vertical members 9 connected by horizontal members 10, and which is connected to the upper part 2 and to the base means 16 by transition portions 12, 17 designed to ensure transmission of forces to and from the upper part 2 and base means 16.
