The 488-metre-long hull of Shell’s Prelude floating liquefied natural gas (FLNG) facility has been floated out of the dry dock at the Samsung Heavy Industries (SHI) yard in Geoje, South Korea.
Once complete, Prelude FLNG will be the largest floating facility ever built. It will unlock new energy resources offshore and produce approximately 3.6 million tonnes of liquefied natural gas (LNG) per annum to meet growing demand.
“Making FLNG a reality is no simple feat,” said Matthias Bichsel, Shell Projects & Technology Director. “A project of this complexity – both in size and ingenuity – harnesses the best of engineering, design, manufacturing and supply chain expertise from around the world. Getting to this stage of construction, given that we only cut the first steel a year ago, is down to the expert team we have ensuring that the project’s critical dimensions of safety, quality, cost and schedule are delivered.”
FLNG will allow Shell to produce natural gas at sea, turn it into liquefied natural gas and then transfer it directly to the ships that will transport it to customers. It will enable the development of gas resources ranging from clusters of smaller more remote fields to potentially larger fields via multiple facilities where, for a range of reasons, an onshore development is not viable.
This can mean faster, cheaper, more flexible development and deployment strategies for resources that were previously uneconomic, or constrained by technical or other risks.
Once complete, the 600,000 tonnes facility will be almost half a kilometre in length (488 metres or 1,601 feet), which is longer than four soccer fields, and will displace six times as much water as the largest aircraft carrier.
It will be moored and hooked up to the undersea infrastructure, around 475 kilometres north-east of Broome, Western Australia. The facility will remain onsite during all weather events, having been designed to withstand a category 5 cyclone.
Shell is the operator of Prelude FLNG in joint venture with INPEX (17.5%), KOGAS (10%) and OPIC (5%), working with long-term strategic partners Technip and Samsung Heavy Industries (the Technip Samsung Consortium).
