Technip Wins Subsea Flowline Gig at Princess Field in GOM

Technip has been awarded a contract by Shell Offshore Inc. for the Princess Gas Lift Flowline project in the Gulf of Mexico. The gas lift flowline is part of the Princess development which ties back to the Ursa TLP in Block MC 809, in water depths of approximately 1,160 meters (3,800 feet). This project follows the successful completion of the Princess Waterflood and Perdido pipeline installation projects carried out by Technip on behalf of Shell and partners in recent years in the Gulf of Mexico. The contract covers:

  • Project management and engineering,
  • Weld, non destructive examination and fatigue qualifications,
  • Fabrication of a 4.5" flowline and a Steel Catenary Riser (SCR),
  • Installation of the flowline and SCR section along with a free issue Pipeline End Termination (PLET),
  • Pre and post lay surveys.

Technip's operating center in Houston, Texas, will execute this contract. The flowline and SCR will be welded at the Group's spoolbase located in Mobile, Alabama. Offshore installation will use the Deep Blue, Technip's deepwater pipelay vessel.

Princess Field Development

Located in Mississippi Canyon Blocks 765 and 766, about 140 miles southeast of New Orleans in 3,650 feet of water, the Princess Field commenced production in 2003.

Spudded in 2002 by the Noble Jim Thompson semisub, the first producing well at the Princess field was drilled to a depth of 27,122 feet.

Shell spudded Princess' first subsea development well, the Eastern Appraisal well, in January 2002, and set a new record for measured depth of 33,200 feet.

The Princess field's initial phase of development consisted of drilling the Northern and Central subsea wells, which were completed in 2003 by the Noble Paul Romano rig.
