Technip has been awarded a lump sum contract by ENI US Operating for the Appaloosa development project in the Gulf of Mexico. This project consists of the tie-back of the Appaloosa well located in Mississippi Canyon, 145 nautical miles (268 kilometers) offshore Mobile, Alabama at a water depth of approximately 2,825 feet (860 meters), to the Corral platform.
The contract covers:
- Project Management and surveys,
- Engineering, fabrication and installation of a 21-mile long (34-kilometer) production flowline(1), a riser(2) and subsea equipment,
- Installation of free issued umbilical(3) and flying leads,
- Pre-commissioning and dewatering of the flowline.
Technip’s operating center in Houston, Texas will execute this contract. The flowline and riser will be welded at the Group’s spoolbase located in Mobile. Offshore installation is scheduled to be completed in the fourth quarter of 2009 using the Deep Blue, Technip’s deepwater pipelay vessel. Extensive saturation diving work will be executed using the Skandi Achiever, one of the Group’s diving support vessels, and umbilical installation using the Deep Pioneer, one of Technip’s deepwater construction vessel. Technip’s scope of work is expected to be completed by 15th April 2010.
(1) Flowline: flexible or rigid pipe laid on the seabed for the transport of production or injection fluids.
(2) Riser: a pipe or assembly of pipes used to transfer produced fluids from the seabed to surface facilities.
(3) Umbilical: an assembly of steel tubes and/or thermoplastic hoses. Umbilicals can include electrical cables or optic fibers to support communications, power supply and telemetry functions.
