TLP Capping Stack

Year Completed:

Jan. 1, 2012


Well Containment Company

Project Description:

Shell awarded Trendsetter the opportunity to provide a capping stack for Tension Leg Platforms (TLPs) in the Gulf of Mexico. Trendsetter designed and manufactured a fit-for-purpose 7 1/16”, 10,000 psi capping stack safely with zero incidents. The final design of the TLP Capping Stack equipment had to meet strict design considerations for temperature extremes, extended subsea depths, overland transport specifics, and ROV friendly interfaces. In December 2012, Marine Well Containment Company (MWCC) acquired ownership of the TLP capping stack.
