The Hammerhead project, located approximately 200 km off the Guyanese coast in water depths of about 1,000 meters, is expected to add between 120,000 and 180,000 barrels per day (bpd) to the country’s overall production capacity, increasing it to nearly 1.5 million bpd once operational [2].
The initial average production capacity of the FPSO is set to be 150,000 barrels of oil per day, with the vessel moored in 1,025 meters of water using SOFEC’s spread mooring system. The FPSO is scheduled to start operations in 2029, subject to required government approvals [2].
MODEC’s involvement in the Hammerhead project follows its successful completion of the FPSO for ExxonMobil Guyana’s Uaru project. The Japanese company’s strategic relationship with ExxonMobil Guyana positions it to continue delivering value throughout the project lifecycle [2].
The total investment for the Hammerhead development is $6.8 billion, with ExxonMobil (operator with 45% interest), Hess (now part of Chevron, 30%), and CNOOC Petroleum Guyana (25%) as partners in the Stabroek block [2].
The contract award for MODEC signifies a significant milestone in the development of Guyana’s oil sector, contributing to the country’s economic growth and energy security.
