Subsea Integration Alliance confirms Bacalhau gig

Subsea Integration Alliance, the partnership between Subsea 7 and OneSubsea, has officially secured the EPCI contract with Equinor for the Bacalhau field in Brazil.


The work scope covers the engineering, procurement, construction and installation (EPCI) of the subsea pipelines (SURF) and production systems (SPS) for the field located 185 kilometers from the coast of São Paulo.

The development will include 140 kilometers of rigid risers and flowlines, 40 kilometers of umbilical, and 19 trees, as well as associated subsea equipment, in water depths of approximately 2,050 meters.

Offshore activities will take place from 2022 to 2023 using Subsea 7’s reel-lay, flex-lay and light construction vessels.

Project management and detailed engineering will take place in Rio de Janeiro with support from Subsea 7’s Global Project Centre in UK and France and various OneSubsea offices.

To remind, Subsea Integration Alliance won an exclusive contract from Equinor for the front-end engineering design (FEED) study on the Bacalhau field at the beginning of last year.

Equinor is the operator of the Bacalhau field with a 40% stake, while ExxonMobil and Petrogal hold 40% and 20% each. Pré-sal Petróleo, a non-investor Government agency, is also a partner in the field.
