Subsea7 has secured a supermajor offshore contract from **Petrobras** for the development of the Sépia 2 field in Brazil, marking a major milestone in one of the world’s most important deepwater oil regions. Located around 280 kilometres southeast of Rio de Janeiro at a water depth of 2,170 metres, the Sépia 2 project sits within the highly productive pre-salt Santos Basin and represents a key phase in Brazil’s ongoing offshore energy expansion.
The Sépia 2 development is widely regarded as one of the largest pre-salt expansion projects, reinforcing Brazil’s role as a global leader in deepwater oil production. Under the agreement, Subsea7 will deliver a full SURF scope covering subsea umbilicals, risers, and flowlines. The contract includes engineering, procurement, fabrication, installation, and pre-commissioning for a total of 17 wells, including two wells connected to the earlier Sépia 1 project, as well as a gas export system featuring 18 risers.
Project execution will begin immediately, with engineering and project management activities carried out across Subsea7’s offices in Rio de Janeiro, Paris, and Sutton in the United Kingdom. Offshore installation operations are scheduled to commence in 2029, reflecting the long-term and complex nature of ultra-deepwater developments in the pre-salt environment.
This award further strengthens the long-standing partnership between Subsea7 and Petrobras, particularly in Brazil’s technically demanding offshore sector. The project will emphasize strong local content, disciplined execution, and close collaboration, supporting infrastructure that is considered critical to Brazil’s national energy strategy. According to Subsea7, contracts of this scale are classified as “supermajor,” meaning they exceed $1.25 billion in value, placing the Sépia 2 project among the most significant offshore engineering awards globally.
The development also highlights broader industry trends, including increased investment in deepwater oil production, rising demand for advanced subsea infrastructure, and the continued importance of long-term offshore projects in ensuring global energy supply. With this contract, Subsea7 further solidifies its position as a leading provider of offshore engineering and subsea construction services, playing a key role in delivering complex energy projects that enhance efficiency, reliability, and sustainability.
