Subsea7 has won a supermajor offshore contract from Petrobras for work on the Sépia 2 field in Brazil’s pre-salt Santos Basin. The field is located about 280,000 m southeast of Rio de Janeiro in water depths of 2,170 m.

Under the contract, Subsea7 will carry out engineering, procurement, fabrication, installation and pre-commissioning for subsea umbilicals, risers and flowlines. The scope covers 17 wells, including two tied to the Sépia 1 project, as well as one gas export line with 18 risers.

The award followed a competitive tender and adds another major deepwater project to Subsea7’s portfolio in Brazil. The company said project management and engineering activities will start immediately from its offices in Rio de Janeiro, Paris and Sutton. Offshore execution is scheduled to begin in 2029.

Sépia 2 was described as one of the largest pre-salt expansion phases and a project with a significant role in Brazil’s energy development. In its statement, Subsea7 also pointed to local content, execution discipline and coordination with Petrobras as part of its delivery approach for the contract.
