ExxonMobil’s pipeline inspection and maintenance programme off the West Coast of Demerara remains scheduled to conclude on December 1, according to an updated Maritime Administration Department notice.
Notice to Mariners No. 184 of 2026, dated November 5, identifies shallow-water barge Neptune 289 and seven supporting vessels engaged in the work.
The notice covers activities extending from the West Coast of Demerara offshore into Guyana’s Exclusive Economic Zone.
It identifies a marine exclusion and work area of approximately 24.2 square kilometres, situated about eight kilometres offshore, and advises mariners to remain clear and navigate with extreme caution. Communication is available through the vessels or Georgetown Lighthouse on VHF Channel 16.
The updated advisory follows ExxonMobil’s October announcement that maintenance would address an unspecified finding on a near-shore section of the Gas-to-Energy pipeline off Crane.
Kiskadee Watch’s October 8 report said the company had scheduled the work from October 14 until around December 1.
Asked what the finding was, ExxonMobil Media Relations Advisor Keisha Gilkes said: “Further testing and evaluation will be done to confirm the exact nature of the issue.”
The report recalled earlier allegations by Opposition Leader Azruddin Mohamed that the pipeline had ruptured, citing bubbling on the water’s surface.
The EPA and MARAD rejected those allegations but acknowledged a “slight anomaly”, saying additional inspections were being undertaken. ExxonMobil said in October that the line contained nitrogen and was not yet operational.
The November 5 notice does not describe the inspection findings or specify the repairs being undertaken.
The pipeline forms part of the Gas-to-Energy development intended to supply natural gas to the power-generation and natural gas liquids facilities at Wales.
