Widened-base structure for supporting an offshore platform

摘要

A widened base, latticed frame work structure for supporting an offshore platform includes four main legs slanting in a lower region and a transition region of the structure and extending parallel in pairs in the front and rear faces in the upper region. A pair of secondary legs aligned with the upper part of the main legs form the launch rails on which the structure can be launched from a barge. The widened base is formed by dihedral external lateral faces and main legs, the structure being fixed to the sea bottom by vertical piles attached to the lower end of the main legs.
