Subsea Integration Alliance, a partnership between SLB OneSubsea and Subsea7, has been selected by Equinor for FEED work on the $12 billion Bay du Nord deepwater oil project offshore Canada.

The award follows a 2024 strategic collaboration agreement between SIA and Equinor, which supported early concept studies for Bay du Nord and other subsea developments.

During the FEED phase, Subsea7 and OneSubsea will work with Equinor and suppliers to develop the subsea architecture, improve execution planning and support engineering, procurement and delivery decisions.

Bay du Nord is located in the Flemish Pass basin, about 500 km northeast of St. John’s. The project was delayed for three years in 2023 after costs increased. Equinor restarted early-stage work in early 2025 by awarding pre-FEED scopes to BW Offshore and Altera Infrastructure.

FID is expected in the next couple of years. First oil could follow as early as late 2028.
