ExxonMobil Guyana will carry out dredging operations in the Stabroek Block offshore Guyana, with operations expected to conclude on November 24, 2026.
According to a Notice to Mariners issued by the Maritime Administration Department (MARAD) on June 6, the activity will be conducted within Guyana’s Exclusive Economic Zone.
“This exercise…will incorporate the use of Suction Dredge Alvar Nunez Cabeca De Vaca which will display the international signal for vessels engaged in such activity. The area is situated approximately 0.8 nautical miles (1.5 kilometers) off the coast of Guyana, and covers an area of 34.8 square nautical miles (119.3 square kilometers),” MARAD said.
The Exclusive Economic Zone (EEZ) of Guyana extends up to 200 nautical miles into the Atlantic Ocean and defines the country’s offshore maritime area, within which it holds rights to resources such as oil, gas, and fisheries. The zone also serves as the primary jurisdiction for offshore petroleum activity and marine resource development.
Dredging the channel is essential to maintain safe navigation to Georgetown port in Guyana by removing natural sediment buildup that reduces water depth. It ensures the channel remains accessible for larger vessels supporting trade and offshore oil logistics linked to activity in the Stabroek Block.
The work forms part of ongoing offshore construction and maintenance supporting Guyana’s oil sector, which produces more than 900,000 barrels of oil per day from four developments in the Stabroek Block.
Additional projects, including the Uaru development, are expected to come on stream and lift national output above one million barrels per day.
Offshore activity in the block is powered by Exxon, which operates with a 45% interest, while Hess (owned by Chevron) holds a 30% interest and CNOOC holds 25%.
