The floating production, storage and offloading (FPSO) vessel planned for ExxonMobil Guyana’s Longtail development is being designed with the highest gas handling capacity ever deployed on an FPSO.
This is according to SBM Offshore Chief Executive Officer Øivind Tangen, in an announcement of the company’s front end engineering and design contract, issued on March 24.
The Longtail vessel is expected to process 1.2 billion cubic feet of gas per day and produce 250,000 barrels of condensate per day. The vessel will also be designed to an upper limit of approximately 1.263 billion cubic feet per day.
“SBM Offshore is well positioned to support the Longtail development, a major gas play demanding the highest gas handling capacity ever deployed on an FPSO,” Tangen said.

Condensate production is expected to average approximately 250,000 barrels per day (b/d), with an upper limit of 290,000 b/d. The FPSO is designed with an upper liquids production capacity of about 304,800 b/d, compared with a targeted total liquids output of roughly 254,000 b/d.
The FPSO will be spread-moored in water depths of about 1,750 meters and will have a storage capacity of around two million barrels of condensate. It will be constructed using SBM Offshore’s Fast4Ward program with its ninth newbuild multi-purpose floater hull and standardized topsides modules.
The development is scheduled to begin production in 2030 and is projected to operate for roughly 30 years.
ExxonMobil Guyana operates the Stabroek Block with a 45% interest. Hess holds a 30% interest. CNOOC holds the remaining 25%.
