ExxonMobil Guyana is considering buying the ONE GUYANA floating production, storage and offloading vessel in early 2026, ahead of the unit’s maximum lease end in August 2027.
SBM Offshore disclosed the update in its recently released third-quarter trading report, which stated that the company is “contemplating the exercise of its contractual purchase option.”
The move would expand Exxon’s ownership of production vessels in Guyana. The company already purchased the Liza Destiny, Liza Unity and Prosperity FPSOs.
ONE GUYANA is SBM Offshore’s largest unit operating in the country. It was built under the Fast4Ward® program, using a newbuild multi-purpose hull and standardized topsides.

The vessel can produce an average 250,000 barrels of oil per day and treat 450 million cubic feet of gas per day. It also has 300,000 barrels per day of water-injection capacity and storage for two million barrels of crude. The FPSO is spread-moored at 1,800 meters of water depth.
The vessel supports Yellowtail, the fourth development in the Stabroek block, located about 200 kilometers offshore. ExxonMobil Guyana operates the block with a 45% stake. Hess holds 30%, while CNOOC has 25%.
SBM Offshore said the ONE GUYANA builds on the “excellent operational performance” of the three preceding FPSOs working in Guyana.
