ExxonMobil plans to use its Proxxima™ technology in the Hammerhead offshore Guyana development and future floating production vessels in the Stabroek Block, as the company expands its use of advanced subsea materials and applications.
The update came during the company’s first quarter 2026 earnings call, when Chief Executive Officer Darren Woods outlined how the company is applying technology across its operations.
Woods said, “we’re on track to leverage our Proxxima™ technology and subsea applications with Hammerhead and future FPSOs, further demonstrating materials performance in demanding offshore environments.”
Proxxima™ is ExxonMobil’s thermoset resin technology designed for use in high-pressure and corrosive operating environments. The material is being applied in subsea pipe systems and infrastructure to reduce weight, improve corrosion resistance and support deepwater operations.

ExxonMobil operates the Stabroek Block offshore Guyana with co-venturers Hess and CNOOC. The company is advancing multiple developments in phases, with Hammerhead among the projects underway.
Hammerhead is ExxonMobil’s seventh sanctioned offshore project in the Stabroek Block. The project will include a floating production, storage and offloading vessel named Essequibo 1899, with first oil targeted for 2029. The vessel is designed to produce about 150,000 barrels of oil per day and 90 million cubic feet of gas per day. It will be moored in water depths of around 1,025 meters using a spread mooring system.
The development plan includes a pipeline to Guyana’s Gas-to-Energy system to transport the gas to shore. MODEC is expected to provide operations and maintenance services for 10 years once production begins. Hammerhead forms part of a broader slate of developments in the Stabroek Block, where output is projected to reach about 1.7 million barrels per day by 2030.
