NOV wins ExxonMobil Guyana contract for heated subsea system at Hammerhead

Dec. 19 (oilnow.gy) U.S. oilfield equipment maker NOV Inc. announced that it won a third-quarter contract from ExxonMobil Guyana to supply an actively heated flexible pipe system for the Hammerhead field development offshore Guyana.

NOV said the scope of work includes the design, engineering, procurement, fabrication and testing of a complete flexible pipe system, expected to comprise four actively heated risers and production flowlines totaling about 14.4 kilometers, along with pull-in latching mechanisms, bend stiffeners, buoyancy modules and topside equipment to support the active heating and monitoring systems. 

The system will combine NOV’s Optiflex flexible pipe technology with active heating to maintain temperature control, improve uptime and enhance restart conditions, the company said in a notice this week.

Jan Rytter, NOV’s Senior Director for New Product Development, Subsea Production Systems, explained, “By combining active heating with flexible pipe technology, we’re directly addressing the critical challenges of deepwater flow assurance, minimizing the need for intervention and supporting consistent field performance throughout the life of the asset.”

Hammerhead is part of ExxonMobil’s expanding offshore portfolio in Guyana, one of the world’s fastest-growing oil provinces.

“Hammerhead reflects the growing application of advanced technologies in deepwater Guyana and we’re proud to support the project with solutions designed to manage complex flow assurance challenges and enable long-term field performance,” Wouter Van Korven, NOV’s Vice President of Sales, Subsea Production Systems, said. 

Expected to start production in 2029, Hammerhead will target oil production of 150,000 barrels per day and gas production at about 90 million cubic feet per day.

Exxon operates the Stabroek Block with a 45% stake, alongside partners Hess (30%, now acquired by Chevron) and CNOOC (25%). The consortium expects total output from its Guyana projects to exceed 1.7 million barrels per day by the end of the decade, with combined hydrocarbons production capacity nearing two million barrels of oil equivalent per day.
