Deepwater Production

  • Fixed Platform (FP) is made up of a jacket (a tall vertical section made of tubular steel members supported by piles driven into the seabed) with a deck placed on top, providing space for crew quarters, a drilling rig, and production facilities. The fixed platform is economically feasible for installation in water depths up to 1,500 feet.

  • Compliant Tower (CT) is made up of a narrow, flexible tower and a piled foundation that can support a conventional deck for drilling and production operations. It is usually used in water depths between 1,000 and 2,000 feet.

  • Tension Leg Platform (TLP) is made up of a floating structure held in place by vertical, tensioned tendons connected to the sea floor by pile- secured templates. Tensioned tendons provide for the use of a TLP in a broad water depth range with limited vertical motion. The larger TLP's have been used in water depths approaching 4,000 feet.

  • Mini-Tension Leg Platform (Mini-TLP) is a floating mini-tension leg platform of relatively low cost developed for production of smaller deepwater reserves which would be uneconomic to produce using more conventional deepwater production systems. It can also be used as a utility, satellite, or early production platform for larger deepwater discoveries. The world's first Mini-TLP was installed in the Gulf of Mexico in 1998.
