Pegged at a massive 250,000 barrels of oil per day, the floating production storage and offloading (FPSO) vessel for ExxonMobil’s fourth project at Stabroek Block has been named One Guyana and will join its sister vessels Liza Unity, Liza Destiny and Prosperity.

Commenting on the start-up of oil production operations last week on the Liza Unity FPSO, Mike Ryan, Production Manager at ExxonMobil Guyana, said, “we have a fourth [FPSO] Yellowtail on the way actually named One Guyana…and we have potentially up to seven to ten oil and gas developments.”

The combined output of these developments will push Guyana’s daily production to well over 800,000 barrels of oil per day by 2025.

The field development plan and application for environmental authorization for the Yellowtail project have been submitted for government and regulatory approval which is expected soon.

Dutch floater specialist SBM Offshore has been awarded contracts to perform Front End Engineering and Design (FEED) for the One Guyana FPSO.

The company said following FEED, subsequent government approvals in Guyana for the development plan and project sanction including final investment decision by ExxonMobil, it will construct, install and then lease the FPSO and operate it for a period of up to 2 years.

SBM Offshore will design and construct the FPSO using its industry leading Fast4Ward® programme allocating the company’s sixth new build, Multi-Purpose Hull combined with several standardized topsides modules.

The One Guyana FPSO will have associated gas treatment capacity of 450 million cubic feet per day and water injection capacity of 300,000 barrels per day. The FPSO will also be spread moored in water depth of about 1,800 meters and will be able to store around 2 million barrels of crude oil.

Building on the experience to date on the Liza Destiny, Liza Unity and Prosperity FPSOs, SBM Offshore said it continues to commit to local content development in Guyana through sourcing fabrication scope locally and the integration of Guyanese engineers in the execution and operational teams.
