Identifying the operational requirements specific to tension leg platforms (TLPs) helps determine the optimum wellhead and production tree design. Because of the special operating conditions and compliant nature of TLPs, the surface wellhead components and completion equipment have design requirements that differ from those on fixed platforms. Designers must consider space restrictions, weight limitations, riser motion and tensioning, alignment, equipment performance, and cost in designing wellheads for use on TLPs. TLPs are still considered a developing technology and, therefore, no unique standards can be established yet for surface wellheads or production tree equipment. Until standards are determined by accepted industry practice, each project will likely include different configurations of surface components and design concepts. The guidelines in this article can help engineers establish a functional specification for surface wellhead and production tree design for a typical TLP project.
