The French oil service company Technip has secured a large subsea installation contract from Shell Development for the Prelude floating liquefied natural gas (FLNG) facility in Australia.
The Prelude FLNG facility is located 200km off the north-west coast of the country in the Browse Basin, at a water depth of approximately 240m.
Technip will instal this facility with the assistance of Samsung Heavy Industries.
Work under the contract includes the project management, fabrication, transport and installation of 12-inch corrosion-resistant, alloy-clad, rigid flowlines and a rigid pipe laid on the seabed.
The deal also includes onshore fabrication of pipeline end terminations; flowline appurtenances and rigid spools; and the transport and installation of the subsea equipment (including manifolds, umbilical termination assemblies, rigid spools and flying leads).
The contract involves in addition the management of key interfaces with the hook-up and commissioning of the FLNG facility with timely transport, installation and handover of the flexible risers, a flexible pipe laid on the seabed and an assembly of steel tubes.
Technip’s operating centres in Perth, Australia, and Kuala Lumpur, Malaysia, will execute the contract, with engineering to commence immediately.
Technip’s spool base in Orkanger, Norway, will be welding the flowline linepipe provided by Shell Development (Australia). Vessels from the group’s fleet will be used for the offshore campaigns, including the Deep Energy and the Deep Orient.
