Equinor agrees concept for Ringvei Vest subsea tie‑back to Troll B

Project scope and resource estimate

Equinor and partners have agreed a concept for Ringvei Vest, a large subsea development to be tied back to the Troll B platform. The concept covers seven discoveries — Grosbeak, Swisher, Mulder, Kveikje, Toppand, Røver Sør and Røver Nord — plus the prospect Grønngylt, across eight licences with seven owners. Equinor estimates Ringvei Vest will contribute about 240 million barrels of oil equivalent.

Development solution and operator role

Equinor, as operator in all licences, acted as area architect and evaluated which discoveries to include and choice of host. The agreed solution establishes a potential common field development and is one of the largest early‑phase projects on the Norwegian Continental Shelf.

Technical concept and infrastructure

The plan is to drill 13 wells via six templates, separate the well stream on the seabed and transport fluids to Troll B. Wells will be controlled from Troll B; oil will be routed to Mongstad and gas to Kollsnes. Troll B will provide power for the subsea facilities and plans include a new compressor to increase processing capacity.

Emissions, context and schedule

Troll B is partially powered from shore, enabling production from Ringvei Vest with low emissions. Equinor framed the project against a maturing Norwegian Continental Shelf where discoveries are smaller and costs rising, stressing development near existing infrastructure. The decision on continuation (DG2) is planned for the end of the year; timing for FID, PDO submission and start‑up remain undecided.
