Technip, an international oilfield services provider, headquartered in Paris, has been awarded a contract by Exxon Mobil Corporation for subsea equipment on the Hadrian South natural gas project in the Gulf of Mexico in Keathley Canyon block 964 in approximately 7,500 feet (2,300 meters) of water.
The project consists of a subsea tie-back to the planned Anadarko operated spar platform, Lucius, which is currently being built in Technip’s yard in Finland.
The contract covers project management, procurement and installation of two 7-mile long flowlines and associated jumpers. Flowline is a pipe, laid on the seabed, which allows the transportation of oil/gas production or injection of fluids. Its length can vary from a few hundred meters to several kilometers.
The contract further covers installation of a 9-mile umbilical, associated foundation and flying leads pre-commissioning. Umbilical is an assembly of steel tubes and/or thermoplastic hoses which can also include electrical cables or optic fibres used to control subsea structures from a platform or a vessel.
Technip’s operating center in Houston, Texas, will execute the contract. The flowlines will be welded at Technip’s spoolbase located in Mobile, Alabama. The Deep Blue, a deepwater pipelay vessel from the Technip fleet will install the subsea equipment in 2013.
