Equinor ASA has let a contract to Subsea Integration Alliance for the operator’s Bacalhau project offshore Brazil. The contract scope covers the engineering, procurement, construction, and installation (EPCI) of the subsea production systems (SPS) and subsea pipelines (SURF).
Subsea Integration Alliance is a non-incorporated alliance between Subsea 7 and OneSubsea, the subsea technologies, production, and processing systems division of Schlumberger.
The development will include 19 trees as well as associated subsea equipment including subsea wellheads, subsea controls and connection systems, and a full completion workover riser. The SURF scope comprises rigid risers, flowlines, and umbilicals.
The Subsea Integration Alliance team established during the initial front-end engineering design phase, awarded in January 2020, will now transition into the full EPCI phase. Project management and detailed engineering will take place in Rio de Janeiro. Offshore activities will begin in 2022 using Subsea 7’s reel-lay, flex-lay and light construction vessels.
Bacalhau field lies 185 km from the coast of the municipality of Ilhabela, in the state of São Paulo, at a water depth of 2,050 m. Bacalhau is Brazil's first integrated SPS and SURF project.
Equinor and partners have made a final investment decision to develop Phase 1 of Bacalhau field in the Brazilian presalt Santos area in June (OGJ Online, June 1, 2021).
Equinor is operator at Bacalhau with 40% interest. Partners are ExxonMobil 40%, Petrogal Brasil 20%, and Pré-sal Petróleo SA (government company, PSA manager).
