SUBMERGED WELLHEAD PLATFORM SYSTEM

Many hydrocarbon fields exist in water depths between 800-2000ft which are not commercially viable using existing methods of production. It is clear that various types of floating production systems (FPS) are viable alternatives to fixed platforms in deeper water depths, as shown by the Green Canyon Block 29 development. The submerged wellhead platform system (SWPS) concept is based on the requirement to produce deep water fields at the lowest cost using proven technology. The paper discusses the design of the submerged jacket, vessel selection,mooring systems, flexible riser configurations, installation, semisubmersible downtime criteria and overall concept economics. Estimates indicate that significant cost savings can be realised using this concept, when compared to existing project developments.
