Dutch floater specialist, SBM Offshore has announced significant progress on the floating production and offloading (FPSO) vessel ONE GUYANA, destined for ExxonMobil’s fourth development in the Stabroek block. The company said the vessel has transitioned from drydock to the quayside at Singapore’s Seatrium yard, marking a crucial phase in its journey towards operational readiness.

The vessel which began construction of its topside modules in September 2022, celebrated the commencement with dual steel strike events at Keppel FELS and Dyna-Mac yards. This vessel is being prepared to augment ExxonMobil Guyana’s existing fleet of SBM Offshore-managed FPSOs, namely Liza Destiny, Liza Unity, and Prosperity, with its operational debut slated for 2025.

Incorporating advancements from SBM Offshore’s Fast4Ward program, the FPSO One Guyana’s design is a testament to the ongoing evolution in offshore production technology. It is set to play a pivotal role in the Yellowtail development project within the Stabroek block, which includes six drilling centers alongside up to 26 production and 25 injection wells.

The project received the green light from ExxonMobil in April 2022, leading to a contractual agreement with SBM Offshore for the FPSO supply. The vessel’s drydock phase began in March 2023 at the Keppel yard in Singapore, where it underwent preparations for its specialized functions in produced water treatment, oil separation, and gas injection.

Designed for peak efficiency, the FPSO One Guyana is equipped to handle a production capacity of 250,000 barrels of oil per day, store up to 2 million barrels of crude oil, treat 450 million cubic feet of gas per day, and inject up to 300,000 barrels of water per day. Positioned for deployment in water depths of approximately 1,800 meters, SBM Offshore highlighted the vessel’s significant capabilities in gas treatment and water injection, underscoring its potential to elevate offshore operations to new heights.

ExxonMobil Guyana Limited, leading the Yellowtail project, possesses a 45 percent stake, with Hess Guyana Exploration and CNOOC Petroleum Guyana Limited holding 30 percent and 25 percent, respectively. ExxonMobil’s ambitious plans include deploying six FPSOs in the Stabroek block by the end of 2027, aiming to exploit the block’s estimated gross discovered recoverable resources exceeding 11 billion barrels of oil equivalent.
