THE ‘ONE GUYANA’ Floating Production Storage and Offloading (FPSO) vessel is expected to arrive in Guyana during the second quarter of 2025, ExxonMobil Guyana President, Alistair Routledge, announced on Tuesday.

Routledge made this revelation at the Jaguar FPSO steel strike ceremony hosted at the Guyana Shore Base Incorporated (GYSBI) in Houston, East Bank Demerara.
The vessel, part of ExxonMobil’s Yellowtail development project within the Stabroek Block, is currently drydocked at the Keppel yard in Singapore.

“We’re anticipating going to Singapore in January for the naming ceremony and the christening of the vessel before it sets sail from Singapore,” Routledge disclosed. “That vessel will set sail for Guyana and arrive here in the second quarter of next year where it will be installed, commissioned and made ready for startup later in the year.”

The vessel design is based on SBM Offshore’s industry leading Fast4Ward® programme that incorporates the company’s new build, multi-purpose floater hull combined with several standardised topsides modules.

The FPSO will be designed to produce 250,000 barrels of oil per day and will have associated gas treatment capacity of 450 million cubic feet per day and a water injection capacity of 300,000 barrels per day.

The FPSO will be spread-moored in water depth of about 1,800 metres and will be able to store around two million barrels of crude oil.

ExxonMobil will take ownership of the FPSO upon completion. The vessel will be part of the Yellowtail development project, which includes six drill centres and up to 51 wells.
In March 2023, SBM hosted the Steel Strike Ceremony at Industrial Fabrications Incorporation (InFab) on the East Coast of Demerara, to signal the commencement of work by the companies—InFab, Guyana Oil and Gas Support Services Incorporated (GOGSSI) and Zeco Group of Services.

With nearly $55 billion earmarked to develop six government-sanctioned projects, the estimated investment for the ‘ONE GUYANA’ FPSO vessel is reported to be approximately $10 billion. ExxonMobil Guyana Limited continues to exceed expectations in oil production with a current daily output of 650,000 barrels of oil, the company has surpassed its initial targets.

The operations are spread across three FPSO facilities – Liza Destiny, Liza Unity, and Prosperity – all of which are operating beyond their nameplate capacities. The ‘ONE GUYANA’ vessel will bolster these production numbers.

Recently, ExxonMobil and its partners’ output hit the 500 million barrels year-end goal, marking a major milestone for Guyana since the start-up in the Stabroek Block five years ago.
The consortium aims to expand production capacity to more than 1.3 million barrels per day by 2027, a target achievable as all six projects are expected to be operational by then.

The financial impact of these operations on Guyana is significant. Since the first production in December 2019, oil revenues and royalties totalling over $5.4 billion have flowed into the Guyana Natural Resource Fund.

Furthermore, the industry has generated substantial local employment, with more than 6,000 Guyanese making up nearly 70% of the workforce on the Stabroek block.

ExxonMobil Guyana Limited serves as the operator with a 45% stake in the Stabroek block, while Hess Guyana Exploration Ltd. holds a 30% interest, and CNOOC Petroleum Guyana Limited owns the remaining 25%.
