Singapore’s Seatrium Limited reports that the Petrobras 78 (P-78) FPSO achieved first oil production, on Brazil’s Búzios field, on December 31, 2025. The milestone marked Seatrium’s successful expansion of its end-to-end capabilities to include offshore commissioning of floating production storage and offloading (FPSO) vessels.

Ordered in 2021, P-78 is the 37th FPSO project delivered by Seatrium to Petrobras. It is the first in a series of six P-Series FPSOs that Seatrium is building for Brazil’s national oil company.

The achievement of first oil marked the final phase of offshore commissioning works. leading to final acceptance of the vessel — the 37th FPSO project delivered by Seatrium to Petrobras —by the customer.

“This is a proud moment for Seatrium – the P-78 achieved first oil in record time, a testament to the agility of our One Seatrium global delivery model and our ability to evolve alongside our customers’ needs to consistently deliver complex, high-quality vessels safely and efficiently,” said Marlin Khiew, executive vice president of Seatrium Energy (Americas). ”This would not have been possible without the continued trust and partnership from Petrobras, as we take the experience and learnings from P-78 to complete our five remaining P-Series FPSO projects, each showcasing innovative sustainability features to support Petrobras’ decarbonization journey.”

Seatrium’s One Seatrium global delivery model saw the group use its facilities in Brazil, China and Singapore to build the P-78, with a substantial portion of the work performed in Brazilian shipyards. T

The FPSO was towed to the Búzios field with all major marine and production systems fully operational, enabling rapid offshore start- up and first oil readiness.

Permanently moored at a water depth of around 2,100 meters using a spread mooring system, the P-78 is one of 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 meters of gas per day. It also provides a minimum crude oil storage capacity of 2 million barrels.

The P-Series FPSOs will incorporate green technologies including Carbon Capture, Utilization and Storage (CCUS) to separate carbon and reinject it into the reservoir for safe storage, thus minimizing the need for gas flaring. The vessels will also feature energy recovery systems for thermal energy, waste heat and gas, as well as seawater deaeration to lower fuel consumption and carbon emissions.
