Oslo/Norway – Technip will provide subsea tie-back to a new Wye piece on an existing pipeline close to an offshore platform in the Gullfaks oilfield in the North Sea. This project is an option to the Snøhvit CO2 Solution project awarded in 2013. The contract covers the:

  • fabrication and installation of two sections of pipe-in-pipe, total length ~9.5 km, with a 13% chrome stainless steel production flowline,
  • installation and tie-ins of three spools and an 8.5-kilometer umbilical,
  • installation of a ~280-ton template and a 110-ton manifold.

Technip’s operating center in Oslo, Norway, will execute the project. Vessels from the Group fleet will install the template in 2015. The flowline will be welded at Technip’s spoolbase in Orkanger, Norway, while the installation will be performed by the Apache II, in the first half of 2016. The installation of the associated manifold, spools, umbilical and other subsea equipment will be performed by other vessels from Technip’s fleet. First gas is planned for the second half of 2016.

The Gullfaks field was discovered in 1978 with an initial recoverable reserve of 2.1 billion barrels. After reaching peak production in 2001, outputs declined to roughly one tenth of 1995's values. The field is currently used to study CO2 injection from natural gas production.
