Technip awarded subsea contract for the Snøhvit CO2 project in Norway
Technip was awarded by Statoil ASA an important(1) lump sum contract for pipelay and subsea installations for the Snøhvit CO2 Solution project. The Snøhvit field is located approximately 140 kilometers north-west of Hammerfest in Norway, in the Arctic Circle, and has been in operation since 2007, following the successful installation of the subsea infrastructure by Technip.
The production of natural gas of this field is based on CO2 being separated at the Melkøya onshore plant and re-injected into the field. The Snøhvit project development will establish an additional well at a new CO2 injection template(2) as well as prepare for gas production from existing templates.
This contract covers:
•fabrication and installation of flowlines(3), including two 5-kilometer 13% chrome stainless steel production flowline and a 5-kilometer CO2 injection flowline,
•installation and tie-ins of spools, jumpers and umbilicals(4),
•installation of a new combined production and injection template and manifold(5).
It will be executed by Technip's operating center in Oslo, Norway. The flowline will be welded at Technip's spoolbase in Orkanger, Norway, while installation will be performed by the Apache II in the first half of 2015. Installation of the associated umbilicals, template, manifold, spools and other subsea equipment will be performed by vessels from Technip's fleet.
Odd Strømsnes, Managing Director of Technip in Norway, stated: "This award confirms Technip's leading position as the contractor of choice for marine installation projects in the Arctic. It also demonstrates our unique abilities when it comes to the fabrication and complex reeling of larger diameter stainless steel flowlines."
