ABSTRACT:
A floating production and storage facility (FPS) or "floating atoll" comprises a very large tension leg platform (TLP) having a regular or irregular polygonal horizontal cross-section (including a circle) and having a centralized opening (moonpool) therethrough. The floater has wave transparent attributes, stanchions sited interior of the moonpool adapted to receive risers and maintain the risers within a limited horizontal zone with reference to the vessel while allowing vertical freedom of motion with reference to the vessel. It also has risers sited in the stanchions and connected to the bottom of the body of water upon which the TLP floats. The risers have sufficient buoyancy means below but near the surface of the water to tension the risers into vertical position, and can have additional buoyancy means distributed over much of their length. The floater can have large oil storage means, and can be moored by lateral mooring as well as the TLP tendons.
