Hunting Subsea Technologies Delivers Connections for FPSO at Guyana Field

Hunting Subsea Technologies, a Texas-based subsidiary of the London-headquartered precision engineering group Hunting, has successfully provided the connections for a floating production storage and offloading (FPSO) unit set to be deployed at a field offshore Guyana by U.S. energy giant ExxonMobil.

The eight titanium stress joints (TSJs) delivered by Hunting will be integrated into the FPSO vessel named Errea Wittu, which will operate at the Uaru development within the Stabroek Block. The Uaru project is considered one of the most significant deepwater developments in the Western Hemisphere in terms of scale and strategic impact.

Upon installation approximately 200 kilometers offshore Guyana, at a water depth of 1,690 meters, the FPSO will have the capacity to produce around 250,000 barrels of oil per day, treat 540 million cubic feet of associated gas per day, and store approximately 2 million barrels of crude oil.

“Our successful delivery to the Uaru project reflects the strength of our execution and the confidence leading operators place in Hunting when performance matters most. As offshore developments become increasingly complex and capital-intensive, we are seeing sustained demand for proven technologies that reduce risk and add long-term value,” said Dane Tipton, Managing Director of Hunting Subsea Technologies.

Hunting boasts being the sole company globally equipped to deliver titanium stress joints at the scale and quality required for full-field offshore developments. These components offer fatigue resistance, structural integrity, and corrosion durability, enhancing performance in deepwater and ultra-deepwater environments.

In addition to the Uaru project, Hunting’s technology has been utilized in projects in the Gulf of Mexico and Brazil. The company recently secured a $31 million TSJ order for the third phase of a deepwater gas development in the Turkish part of the Black Sea.

The Errea Wittu FPSO will be the fifth vessel in the Stabroek Block and the first FPSO from Japan’s MODEC. MODEC recently received the topsides modules for the unit at the BOMESC yard in Tianjin, China, with the hull sailaway ceremony taking place in late June.

The final investment decision (FID) for the Uaru project, the fifth development in the Stabroek Block, was made in April 2023. The total investment in the project is estimated to be $12.7 billion. ExxonMobil Guyana holds a 45% interest in the block, with Hess Guyana Exploration LTD (30%) and CNOOC Petroleum Guyana Limited (25%) as partners.
