On 2 January 2026, Seatrium said P-78 began producing oil on 31 December 2025, describing the project as its first FPSO delivery completed under a full EPCC scope that also covered commissioning activities offshore. Awarded in 2021, P-78 is the first of six P-Series units being built for Brazil’s national oil company Petrobras (Petroleo Brasileiro S.A.), and the group linked the milestone to the closing stage of work leading to the customer’s Final Acceptance. Seatrium also stated this was its 37th FPSO project delivered to Petrobras.

Marlin Khiew, Executive Vice President of Seatrium Energy (Americas), attributed the schedule outcome to the One Seatrium Global Delivery Model and to cooperation with Petrobras, adding that lessons from P-78 will be applied across the remaining five P-Series projects.

The group said fabrication and integration drew on its footprint in Brazil, China, and Singapore, and that the vessel was towed to the Búzios field with major marine and production systems already in operation to enable a rapid start-up at the site.

Búzios sits in the Santos Basin around 180–230 km off Rio de Janeiro. P-78 is permanently moored in about 2,100 m water depth using spread mooring, and is designed for up to 180,000 barrels of oil per day and 7.2 million cubic metres of gas per day, with minimum crude storage of 2 million barrels.

Across P-78, P-80, P-82, P-83, P-84, and P-85, Seatrium said the series will include CCUS for CO₂ separation and reinjection, alongside thermal and waste-heat recovery and seawater deaeration. The six projects are expected to add 1.3 million barrels per day of production capacity for Brazil and to create over 60,000 jobs in communities where Seatrium’s Brazilian yards operate.
