Abstract

A jackdown tension leg platform is set forth which may be used for processing a commodity liberated from the ocean floor by one or more wells. The platform includes a closed buoyant hull which houses production equipment and at least one connector disposed on the hull for vertical relative movement. The connector has one end secured to the ocean floor and is moved upwardly relative to the hull to submerge the hull to a depth below the majority of the ocean's hydrostatic forces and, at the same time, tension the connector to hold and stabilize the hull over the wells. Conduits are connected between the wells and the submerged hull and between the hull and the surface. A crew module may be provided above the surface atop the connector with a trunk disposed between the module and submerged hull to provide access therebetween. Additionally, where the commodity is combined at a manifold located in a closed ocean floor mounted shell, a descending and ascending capsule may be provided to transport crew members between the shell and submerged hull.
