Technip awarded two subsea contracts for the Caesar/Tonga field in the Gulf of Mexico
Technip has been awarded two lump sum contracts by Anadarko Petroleum Corporation as Unit Operator for the Caesar/Tonga oil field development in the Gulf of Mexico. This field is located 190 miles (300 kilometers) from New Orleans (in Green Canyon Blocks 683, 726, 727 and 770), in water depths of around 1,500 meters (5,100 feet). It will be tied back to the Constitution(1) Spar platform.
The first contract covers the design and supply of the components for four pipe-in-pipe flowlines and the installation of these flowlines, representing a total of 27 miles (43 kilometers). It also includes the design, fabrication and installation of eight pipeline end terminations (PLETs). This development will use the pipe-in-pipe(2) technology, which provides insulation and flow assurance for effective production in deep and ultra-deep water. Technip’s operating center in Houston, Texas will execute this contract. The pipe-in-pipe flowlines will be welded and assembled at the Group’s spoolbase located in Mobile, Alabama. Offshore installation will be carried out with the Deep Blue, Technip’s deepwater pipelay vessel.
The second contract covers the project management, engineering and fabrication of two control umbilicals(3) and their termination hardware. This contract, which is scheduled to be completed in the third quarter of 2010, will be executed by Duco, Technip’s wholly-owned subsidiary in Houston, Texas. The umbilicals will be manufactured at the Group’s plant in Channelview, Texas.
(1) Constitution is a floating spar platform designed and fabricated by Technip in 2004-2005.
(2) Pipe-in-pipe flowline: steel pipes assembly consisting of a standard production pipe surrounded by a so-called carrier pipe. The gap between the carrier and production pipes is filled with an insulation material.
(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.
