Abstract: An offshore platform assembly includes a platform 12, four legs 10 and four footings 18. Each leg 10 is coupled to the platform by upper and lower bearings which are pivotable in a direction of inclination of the legs, the upper bearing being fixed with respect to translational movements, whilst the lower bearing can slide in a plane common with the plane of the platform 12. In an alternative embodiment, the lower bearing may be fixed and the upper bearing sliding. This assembly enables the platform to be used in high waters and prevents bending of the legs, which can occur with prior art systems.

Abstract: The invention relates to an offshore platform assembly which uses inclined legs. The improved assembly provides for the use of a floatable hull which has a plurality of cylindrical wells extending vertically through the hull body and a plurality of legs which are supported by the hull in transit and which support the hull in a working condition. Each chord of the supporting leg passes through a corresponding well formed in the hull and compresses a flexible guide positioned within the well of the hull to reduce the bending moment imposed on the leg during elevation of the hull, induced by the sagging of the hull or by severe storm. The flexible guide has a compressible member which moves laterally, to a limited distance, to absorb the bending moment. The compressible member can be a resilient sleeve, a spring or other laterally movable and adjustable member.
