Re-gasified liquefied natural gas (RLNG ) supply to the country’s maiden FSRU recommenced on Thursday morning after a 12-day disruption through resolving the glitch in an underwater hydraulic valve.
US-based Excelerate Energy’s vessel Excellence restarted re-gasifying LNG at around 6:30 am, which reached Chattogram area at around 10:00 am at 100 million cubic feet per day (mmcfd). Re-gasification increased to around 126 mmcfd at around 12:40 pm. Supply of RLNG will peak up gradually.
KGDCL started taking less gas from the national gas-grid after resumption of LNG re-gasification, which improved the overall gas supply in Dhaka and its adjoining areas.
Excellence had around 76,000 cubic metres of LNG stored onboard when re-gasification was terminated.
Re-gasification will continue until the next LNG vessel reach at Moheshkhali floating LNG terminal, which is scheduled for November 21.
Petrobangla had to cancel two LNG cargoes, each having around 140,000 cubic meter capacity, from the lone supplier Qatar’s RasGas due to the outage of re-gasification from the floating terminal on November 3 due to a faulty underwater hydraulic valve.
The ‘actuator valve’ in between the FSRU (floating, storage, re-gasification unit) and subsea pipeline was leaked then, resulting in total halt of re-gasification at Excelerate Energy’s terminal.
The authorities had to shut several gas-fired power plants and a fertiliser factory in the aftermath of the supply halt.
Excelerate Energy’s FSRU arrived at Moheshkhali terminal carrying the country’s first LNG on April 24.
But it got connected to the subsea pipeline network on August 05, and commenced injecting the first regasified gas on August 12.
Technical issues and rough seas during the June-August south-western monsoon kept it stranded off the south coast of Chattogram for months.
Petrobangla started regular import of LNG from Qatar’s RasGas from September 9 after successfully initiating the feeding of RLNG to consumers from August 18.
