ExxonMobil Guyana said on Wednesday it has removed the faulty discharge silencer from the Liza Destiny Floating Production Storage and Offloading (FPSO) vessel for further assessment of the damage to determine the necessary scope of repairs needed.
The company said the replacement/repairs are estimated to take “approximately three months.”
Exxon also said plans initiated in 2020 to install a redesigned third-stage flash gas compression system at the end of this year remains on schedule.
“We have begun to slowly ramp up production to between 100,000-110,000 barrels per day at a flare level of no more than 15 million cubic feet of gas per day,” ExxonMobil Guyana Public and Government Affairs Advisor, Janelle Persaud said. “These operating parameters were defined after careful consideration of safety, environmental, technical and economic factors as well as discussions with the relevant government agencies on the best path forward while repairs and upgrades are ongoing.”
The company noted as well that is “extremely disappointed” at the ongoing technical challenges, but it “remains proud of the team offshore” that continues to work safely and manage operations efficiently during the COVID-19 pandemic.
“We will continue to work with the relevant parties to rectify the situation as soon as possible,” Persaud said.
ExxonMobil said last week that as the final testing phase of the reinstalled flash gas compressor and other components of the system was being conducted, an additional problem with the discharge silencer was encountered. As a result, production was reduced to around 30,000 bpd.
