Deep Gulf Energy II has awarded Technip a lump sum contract for the development of the deepwater, high-pressure, high-temperature Kodiak field, in Mississippi Canyon Blocks 727 and 771, in the Gulf of Mexico.
The in 1472-1710m water depth project consists of a subsea tie-back to the Devils Tower Truss Spar in Mississippi Canyon Block 773.
To withstand Kodiak field’s high-temperature and pressure, as well as extremely corrosive production fluids, the pipeline, which is due to be installed by reel-lay, will be bi-metallic, i.e. carbon steel pipeline which is mechanically or metallurgically lined with a corrosion resistant alloy line pipe.
This contract covers: project management; fabrication and installation of more than 12km of reeled bi-metallic flowline and riser; installation of an 11km umbilical, associated terminations and flying leads; pre-commissioning and testing for the rigid line; crossings preparation along with pre-lay and post-lay survey.
Technip's operating center in Houston, Texas, USA, will perform the overall project management. The infield flowline and riser will be welded at the group’s spoolbase in Mobile, Alabama, USA. The offshore installation is expected to be performed in H2 2015 by Technip’s purpose-built pipelay and subsea construction vessel Deep Blue and the Global Orion, a support vessel.
