Prelude FLNG will remain closed in the first quarter of 2022

Oil major Shell expects Australia’s Prelude FLNG unit, the world’s largest unit of this type, to remain closed for most of the first quarter of 2022.

World’s largest FLNG facility LNG resumed in January 2021 Freight transportation, Almost one year after shutdown due to electric tripAfter a sudden power outage, it was shut down again in December 2021, after which attempts to reestablish reliable power on board failed.

In a Q & A Thursday, CEO Ben Van Baden told reporters that the Prelude would remain closed for most of the first quarter of 2021 as part of Shell’s results presentation.

Van Beurden said: “Of course, Prelude has a tooth-growth problem. Of course, it’s a unique asset, and as you can imagine, it has a very unique challenge.”

“As a matter of fact, [..] There was pretty good reliability in the second half of last year.But then[…] In December, one of the battery systems associated with an uninterruptible power supply failed. These issues should be resolved comprehensively and carefully before rebooting. “

“As you can imagine, it wasn’t easy because of the pandemic. It’s difficult to get people in because it’s remote. To hire a vendor specialist, you need to quarantine for a few weeks before boarding. So these problems make the problem a little worse. “

“But again, every time I reboot, I just want to make sure that the problem is resolved and that it can be safely resolved.”

“We are working closely with the regulatory agency NOPSEMA.”

“But sure, [Prelude FLNG] It has been released at this time and will be released most of the first quarter so far. “

NOPSEMA order

NOPSEMA, Australia’s oil and gas industry safety regulator, closed the Prelude FLNG facility in Shell in December 2021 to provide the facility with adequate power and a safety system in place. I ordered it to stop until I was convinced.

NOPSEMA believes that power loss will affect the residence and working conditions of facility staff, and by December 6, 2021, failure to restore reliable power will represent continued health consequences and risks. Said it was done. The safety of the people in the facility and NOPSEMA arranged to visit the facility.

According to NOPSEMA, power outages have a direct impact on emergency response capabilities, operation of safety-critical equipment (communication, access to safety-critical documents and information, work permit systems, etc.), and evacuation of personnel by helicopters and boats. rice field.

Key services such as lighting, safety systems, communication systems, drinking water systems, sewage treatment and HVAC were also affected, with seven people being treated for heat-related conditions.

The functions of the process equipment required to effectively manage LNG inventory were also affected.

Therefore, NOPSEMA has ordered the shell to stop LNG production from the Prelude FLNG unit. This is until “the facility can safely restore critical power and important services associated with critical power after a power outage, and the safety system and critical support can show NOPSEMA satisfaction. The system keeps personnel safe. Works to do. “

The 488-meter-long shell-type prelude FLNG unit forms part of an offshore development that produces natural gas from a remote oil field of the same name, approximately 475 km northeast of Bloom, Western Australia.

The first LNG shipment from the project (originally approved in 2011) was returned to Asian customers via the Valencia Knutsen LNG tanker in June 2019. Shell is the project operator and other partners are INPEX, CPC and KOGAS.
