ExxonMobil Guyana completes purchase of ‘One Guyana’ FPSO 

ExxonMobil Guyana Ltd has completed the purchase of FPSO ONE GUYANA from SBM Offshore, finalising the transaction ahead of the unit’s maximum lease term, which was due to expire in August 2027.

The completion was announced on Tuesday in Amsterdam, with SBM Offshore confirming that ExxonMobil Guyana will now assume ownership of the floating production, storage and offloading vessel, while SBM Offshore will continue to operate and maintain the FPSO until 2035.

The transaction involved a total cash consideration of approximately US$2.32 billion, with the proceeds primarily used to fully repay US$1.74 billion in project financing, significantly reducing SBM Offshore’s net debt position.

The ONE GUYANA is a massive Floating, Production, Storage, and Offloading (FPSO) vessel, operating as the fourth and largest oil production facility in Guyana’s Stabroek Block. It achieved first oil in August 2025, ahead of schedule, marking a major milestone in Guyana’s rapid offshore development. 

FPSO ONE GUYANA will continue to run under an integrated operations and maintenance model, combining the technical expertise of both SBM Offshore and ExxonMobil Guyana.

SBM Offshore said the financial impact of the transaction will be reflected in its 2026 guidance, to be released as part of the company’s Full Year 2025 earnings report scheduled for February 26, 2026.
