ExxonMobil Guyana has deployed four offshore support vessels as subsea installation work continues for the Uaru development, advancing preparations for the arrival of the Errea Wittu floating production, storage and offloading (FPSO) vessel later this year.
Separate notices issued on August 3 by the Maritime Administration Department (MARAD) identified the vessels as the AHT Boka Defender, AHT Boka Sweeper, AHT Boka Forward, and AHT Boka Keeper, all owned by Boskalis.
According to MARAD, the subsea activities for the Errea Wittu FPSO are expected to continue until December 31, 2026.
“The area of operation location is situated approximately 101.6 nautical miles (187.16 kilometers) off the Coast of Guyana and covers an area of 3.58 square nautical miles (12.285 square kilometers),” the agency stated.
The four Boskalis vessels are DP II anchor handling salvage tugs built to support offshore installation campaigns. Their capabilities include heavy anchor handling, ocean towing, mooring installation, salvage and offshore construction support. The Boka Defender and Boka Keeper are also equipped with remotely operated vehicle (ROV) preparation facilities for subsea work.
The Errea Wittu FPSO, constructed by MODEC, remains on schedule to arrive in Guyana and begin production before the end of 2026.
Designed to develop the Uaru field, the US$12.7 billion project targets more than 800 million barrels of recoverable oil. It will include up to 10 drill centers and 44 wells and is expected to produce 250,000 barrels of oil per day, lifting Guyana’s production beyond one million barrels per day.
The FPSO will feature a combined-cycle gas turbine to improve power generation efficiency and a closed-loop flare system designed to reduce greenhouse gas emissions during operations.
ExxonMobil operates Guyana’s Stabroek Block with a 45% stake, with co-venturers Hess, owned by Chevron (30%), and CNOOC (25%).
