SELF-CONTAINED OFFSHORE PLATFORM

摘要

A self-contained jack up type drilling and production platform structure comprising a flotatable barge-like hull with support legs which can be jacked up and down to lower and raise the hull with respect to the surface of the sea. A removeable drilling module rests on top of the hull and extends over an opening therein between two of the support legs. Production equipment is arranged in the hull and communicates with the opening. Moveable conductor supports extend between the legs of the platform and serve to brace the drill string and production conduit conductors.
