Technip gets subsea compression contract

By OGJ editors

Statoil has let a contract to Technip for work on what it calls the world’s first subsea natural gas compression facility, to be installed in Asgard area in the Norwegian Sea.

The company expects the project to increase recovery from Mikkel and Midgard gas-condensate fields by 278 million bbl of oil equivalent hydrocarbons as part of its broader strategy to extend production from the Norwegian Continental Shelf.

Statoil submitted Asgard subsea compression plans to the Norwegian government last year (OGJ Online, Aug. 16, 2011).

Mikkel and Midgard wells are completed subsea in 240-310 m of water, with wellstreams combined and processed on the Asgard B semisubmersible platform.

Statoil plans to install a subsea template with two compressors, coolers, separators, and pumps about 40 km east of Asgard, plus a submarine cable for power.

Technip will fabricate, install, and tie in pipeline spools, including protection covers, and power cables, and umbilicals. The contract has options for engineering, fabrication, and supply of a special handling system for the installation and retrieval of the subsea compression system modules and the initial installation of the subsea compression system modules.

Aker Solutions is handling topsides modification and providing a full-scale subsea compression system (OGJ Online, June 20, 2011; Dec. 1, 2010).

Asgard interests are Statoil 34.57%, Petoro AS 35.69%, Eni Norge AS 14.82%, Total E&P Norge AS 7.68%, and ExxonMobil Exploration & Production Norway AS 7.24%.

Mikkel licensees are Statoil 43.97%, ExxonMobil E&P Norway 33.48%, Eni Norge 14.9%, and Total E&P Norge 7.65%.
