France's Technip said Friday that it has won a subsea installation contract from Shell Development (Australia) for the Prelude Floating Liquefied Natural Gas (FLNG) facility.
The facility is moored around 124 miles (200 kilometers) off the northwest coast of Australia, in the Browse Basin, at a water depth of approximately 787 feet (240 meters).
The contract covers the project management, fabrication, transport and installation by reeling of 12 inch flowlines and the fabrication of pipeline end terminals, flowline appurtenances and rigid spools. It also includes the transportation and installation of the subsea equipment including manifolds, umbilical termination assemblies, rigid spooks and flying leads.
The offshore work will be carried out using the Deep Energy pipelay vessel and the Deep Orient flexlay construction vessel.
"This award represents a key milestone for Technip, achieving the first reel-pipelay project in the region for the new-built vessel, the Deep Energy," Technip said in a statement.
Shell expects the Prelude FLNG project to be ready in 2017, it said in May 2012. Once operational, the Prelude FLNG facility will produce at least 5.3 million tonnes per annum (mtpa) of liquids (3.6 mtpa of LNG, 1.3 mtpa of condensate and 0.4 mtpa of LPG). The FLNG will be built by South Korea's Samsung Heavy Industries, in Geoje Island shipyard.
Shell is the main equity holder and the operator of the WA-44-L, an area which covers 386 square miles (1,000 square kilometers) in the Browse Basin, Western Australia. Shell discovered the Prelude gas field in 2007. It subsequently discovered the Concerto gas field in March 2009. Both gas fields have around 3 trillion cubic feet of liquids-rich gas.
