Engie E&P Norge has awarded Rosenberg WorleyParsons a front-end engineering and design (FEED) study for modifications at the Gjøa platform in the Norwegian North Sea as part of the Skarfjell subsea tieback project.
Skarfjell is in license PL418, operated by Wintershall, and will be tied back to the Gjøa platform, operated by Engie E&P Norge.
Rosenberg WorleyParsons will provide a FEED-study to plan the required modifications to the Gjøa installation. The contract also includes an option for the execution phase of the project – engineering, procurement, construction, installation and commissioning.
Engie says its strategy is to make Gjøa a hub for future fields in the area and to extend the lifetime of the Gjøa platform.
Skarfjell is in the northeastern North Sea about 20km southwest of the Engie-operated Gjøa platform, and some 130km northwest of Bergen. Skarfjell is expected to yield between 60-140 MMboe.
The Skarfjell reservoir will be developed with two subsea templates tied back to the Gjøa platform for processing and export. Gjøa will also provide lift gas to the field and water injection for pressure support.
