HOUSTON — Technip set two industry records for ultra-deepwater pipeline installation with its work on Shell’s Perdido development in the U.S. Gulf of Mexico. Technip performed the deepest reeled flowline installation at a water depth of 2,961 meters (9,713 ft) and the deepest reeled steel catenary riser installation at a water depth of 2,469 meters (8,100 ft).
Installation was successfully completed in January 2009. The flowline and riser had a total length of 13.2 kilometers (8.2 miles).
Technip’s operating center in Houston executed the contract. Welding operations took place at Technip’s spoolbase located in Mobile, Alabama. The offshore installation was performed using Technip deepwater pipelay vessel Deep Blue.
Under the terms of separate contracts, Technip supplied the Perdido umbilicals as well as the hull and mooring system for the spar platform, a cylindrical, partially submerged offshore drilling and production platform. Moored in about 2,400 meters (8,000 ft) of water in Alaminos Canyon Block 857, the spar will be the deepest spar production facility in the world and the first with direct vertical access.
