Neptune Gets Green Light for Pair of North Sea Tiebacks

Neptune plans to tie back the Duva and Gjøa P1 to the existing Gjøa platform in the Norwegian North Sea, which it currently operates.

Norwegian authorities have approved development plans for two Neptune Energy projects in the North Sea: Duva and Gjøa P1, a pair of fields that will be developed through subsea tiebacks to the nearby Gjøa platform.

First production from the two projects is expected in late 2020. Neptune estimates total recoverable resources to be around 120 million BOE. At its peak, Duva is expected to produce 30,000 BOE/D, while Gjøa P1 will produce 24,000 BOE/D.

“With these plans approved, we remain on track for the successful execution of these important projects,” Odin Estensen, Neptune managing director, said. “Not only do these developments strengthen Gjøa’s position as a major hub in the northern North Sea, they demonstrate our ambitions to continue growing our business on the Norwegian Continental Shelf.”

Neptune submitted development plans in February. Duva will be developed with a four-slot subsea template and tied back to the Gjøa platform for processing and export. The field will have three production wells—two oil producers and one gas producer—with the potential for an additional oil well. Gjøa P1’s development falls under the larger development plan for the Gjøa field, which started production in 2010. The P1 segment is located in the northern part of the field. Duva is located approximately 3.7 miles northeast of the Gjøa field.

“The approval of the plans allows us to start this summer with the first step in our parallel project execution—the subsea installation of the Duva template,” said Erik Oppedal, Nepture projects and engineering manager.

TechnipFMC will deliver the subsea tiebacks utilizing the Neptune Subsea Alliance Agreement, and Rosenberg Worley will perform the topside modifications.
