Shell Development (Australia) has awarded a subsea installation contract to Technip for its Prelude floating liquefied natural gas (FLNG) facility.
The FLNG has been moored at a water depth of 240m some 200km off the north-west coast of Australia, in the Browse Basin.
Under the terms of the contract, Technip will be responsible for project management, fabrication, transport and installation by reeling of 12" corrosion resistant alloy clad rigid flowlines.
It will also undertake onshore fabrication of pipeline end termination, flowline appurtenances and rigid spools.
Subsea equipment including manifolds, umbilical termination assemblies, rigid spools and flying leads will be transported and installed.
Shell will provide the flowline linepipe, which will be welded by Technip's spoolbase in Orkanger, Norway.
Once completed, the Prelude FLNG facility will be the biggest of its kind in the world and will feature a double-hulled steel body.
It will be 488m long, 74m wide and weigh about 600,000t. It will comprise of 0.26t of steel with a deck area longer than four football fields.
