Prelude offloaded its first shipment of LNG in June 2019 to the Valencia Knutsen , which shipped it to customers in Asia .
truly enormous . For example , the Gas Production Swivel Inner Part , forged in solid duplex , weighs 14500 kg and measures 2450mm outside diameter . The Gas Production Swivel Outer Part , also forged in solid duplex , weighs 17200 kg and measures 2990mm outside diameter . During fabrications there were concerns that during the solution heat
treatment of these very thick items , the interior would cool down much more slowly than the exterior of the part , increasing the potential for the precipitation of detrimental phases . The SBM team developed special methods to deal with this challenge : see the text box on the previous page ‘ Original feature story ’ to find out more .
Go bigger to be smaller ? It ’ s hard not to picture Prelude as a giant of the seas , but paradoxically it ’ s the miniaturisation that the design represents that makes the vessel economically feasible . The huge hull is still far smaller than an onshore refinery , and Shell Oil describes it as “ more environmentally friendly ” than an onshore plant . Given that it is located far out at sea , Prelude does not have the same environmental impact as onshore refineries with respect to land use , pipelines , and risks to local populations .

Six-year maintenance contract
This July , Wood secured a six-year contract to provide brownfield engineering , procurement , and construction management ( EPCm ) solutions for Prelude . Ken Gilmartin , CEO at Wood , said , “ LNG is a key transition fuel as ( the ) industry balances the need for global energy security with the importance of urgent reduction in carbon emissions . We are delighted to build on our 70-year global relationship with Shell to deliver integrated brownfield engineering solutions for Prelude , the world ’ s largest floating offshore gas facility .”
