Engie Dishes Out Gjoa FEED Study Deals
Tuesday 4 April 2017
French player Engie has handed out a trio of front-end engineering and design study contracts related to its Gjoa platform off Norway.
Italy's Saipem, Dutch outfit Heerema Marine Contractors and Norway's Kongsberg Maritime have shared in the work, which is linked to German player Wintershall's plans to tie its Skarfjell discovery back to Gjoa through a subsea solution.
Saipem and Heerema's deal related to offshore heavy-lifting work. The scope covers "two separate and parallel studies that will clarify the different options for safe and efficient lifting and installation" of the Skarfjell module onto the Gjoa platform.
Kongsberg's FEED study is in relation to the upgrading of control and safety systems on Gjoa ahead of the tie-in.
All three contractors are set to begin and finish their studies in August.
Wintershall decided in early February to press ahead with a subsea tie-back to Gjoa for Skarfjell, ditching other standalone options such as using the Teekay Offshore-owned Petrojarl Varg floating production, storage and offloading unit or a semi-submersible unit.
Output from Skarfjell will be transported subsea to Gjoa some 20 kilometres to the north-east in the North Sea, where it will be processed and exported. Gjoa will also provide gas lift services to the field and water injection for pressure support to a second template.
Wintershall in mid-February submitted its selected development concept to Norwegian authorities. Several studies will now be carried out before a final investment decision and concurrent submission of a field development plan to the Petroleum & Energy Ministry.
Gjoa is a semisub production unit that is operated with power from shore through a 100-kilometre-long subsea cable from Mongstad.
Engie operates Gjoa on 30%, with Norwegian player Petoro on 30%, Wintershall on 20%, Shell on 12% and DEA on 8%.
