Project description

Shell’s Prelude floating liquefied natural gas (FLNG) facility, is now fully operational and shipped its first LNG shipment in June 2019. The Prelude FLNG facility is the first deployment of Shell’s FLNG technology, which extracts, liquefies and stores gas at sea, before it is exported to customers around the globe. 

In 2024, at the expiry of the Monadelphous' existing contract with Shell, it was extended for a further seven years. Monadelphous will continue providing onshore project management and planning services at Shell’s head office in Perth, Western Australia and offshore maintenance services at Prelude FLNG, located in the Browse Basin.

Scope of work
