HOUSTON, July 21 -- Woodside Energy Ltd., operator of the North West Shelf Venture, let a $200 million contract to J. Ray McDermott SA subsidiary McDermott Industries (Australia) Pty. Ltd. for substructure and pipelay installation at Angel gas-condensate field off Australia.

The $1.2 billion project includes the installation of the venture's third major platform on the North West Shelf.

The remotely operated processing platform will be installed in 80 m of water about 49 km east of the venture's North Rankin production facility, to which it will be connected by a new pipeline.

The 7,500-tonne jacket substructure and 7,000-tonne topsides are expected to be fully operational by fourth quarter 2008. Eight drilled and grouted, piled foundations weighing more than 3,000 tonnes each will secure the jacket to the seabed (OGJ Online, Jan. 2, 2006, Newsletter).

The contract covers transportation of the jacket and piles from a fabrication yard in China via J. Ray's Intermac 650 launch barge, as well as the launch, upend, and set down of the jacket. Another J. Ray marine vessel will install the jacket and pipelines.

Installation is scheduled for completion by fourth quarter 2007, ensuring the jacket is in place before the cyclone season. The CRA pipelines and 30-in. pipeline installation will be completed during first quarter 2008.
