Wintershall, which has recently submitted NOK9.9bn ($1.2bn) development plan the Nova field in the North Sea, plans to develop the field utilizing two subsea modules tied back to the nearby Neptune Energy-operated Gjoa platform for processing and export.

Scheduled to commence production in September 2021, the field is estimated to hold recoverable reserves of about 12.2 million standard cubic meters of oil equivalents (77 million barrels).

Under the three-year EPCIC contract, Rosenberg WorleyParsons will be responsible for the construction and installation of a new Nova topside module.

Rosenberg WorleyParsons plans to execute the contract from its office in Stavanger, Norway. The engineering and construction of the modification project is expected to engage about 300 people.

The Gjøa platform will provide lift gas to the Nova field and water injection for pressure support whereas power for the field comes via the platform from shore.

Rosenberg WorleyParsons will commence the work immediately and is a continuation of the Front End Engineering and Design (FEED) which the firm already conducted.

Neptune Energy Norway country director Anne Botne said: “We are pleased to award such a significant contract to Rosenberg WorleyParsons, who have already delivered major milestones under the FEED phase of this important development project on the Norwegian Continental Shelf.

“The tie-back from Nova validates our initial design for Gjøa as a hub for the wider area, and we look forward to continued cooperation with Wintershall and other project partners.”

Neptune Energy is the operator of the Gjøa license with 30% stake while other partners include A/S Norske Shell with 12% interest, DEA Norge with 8% stake, Petoro with 30% interest and  Wintershall Norge with 20% stake.
