The operation includes multiple support vessels that will display international signals for vessels engaged in offshore work. These include the C-Installer, Skandi Nomad, Seacor Congo, Seacor Amazon, C-Confidence, Sanibel Island, Shepherd Tide, Michael Crombie McCall, Guyana Hero, Gerard Tide and others listed in the notice.
The drill center covers an area of approximately 0.29 square nautical mile (1 square kilometer).
The Hammerhead development is ExxonMobil’s seventh sanctioned offshore project in the Stabroek Block. The project will be developed using 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.
