Seatrium Limited, on 11th March 2026, announced the successful first gas injection for the PETROBRAS 78 (“P-78”) on 2 March 2026. The achievement came just 61 days after the vessel reached First Oil on 31 December 2025, marking a rapid progression toward full operational capability. The completion of first gas injection represents a significant step as the vessel transitions from the execution phase into full operational readiness. The milestone enhances the production potential of the Búzios field beyond conventional oil output. With the first gas injection milestone completed, the P-78 strengthens its role in supporting Brazil’s energy security and maintaining long-term production stability in one of the country’s key offshore regions.
The P-78 is deployed in the Búzios field in the Santos Basin, located approximately 180 to 230 km off the coast of Rio de Janeiro, Brazil. Permanently moored at a water depth of around 2,100 meters using a spread-mooring system, the vessel ranks among the largest FPSOs ever delivered to Brazil. The facility is designed to produce up to 180,000 barrels of oil per day and 7.2 million cubic metres of gas per day, with a minimum storage capacity of 2 million barrels of crude oil. Through the six P-Series FPSO projects Seatrium is building – P-78, P-80, P-82, P-83, P-84 and P85. Brazil is expected to gain an additional 1.305 million barrels of oil per day of production capacity.
The achievement was supported by extensive collaboration with Petrobras and Seatrium’s international vendor network. Together, they worked to ensure that critical systems were fully prepared for operation, including the main process compressors, export compressors, and gas injection compressors. These systems are essential to enabling the safe and efficient introduction of gas injection into the production process. Throughout the development and commissioning phases, Seatrium maintained strict safety, quality, and operational standards across all participating facilities. Delivering the first gas injection according to schedule reflects the company’s strong Health, Safety and Environment performance, as well as its consistent track record of completing complex offshore energy projects on time.
Following the successful milestone, Seatrium is moving forward toward the next key phase of the project, which includes completion of the delivery stage and the Final Acceptance of the vessel by Petrobras. The company is focused on ensuring a seamless transition to full operations and supporting the long-term performance of the FPSO.
