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.
