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.
