Woodside awards $200m Angel jacket contract

NORTH West Shelf Venture operator Woodside Petroleum has awarded a contract worth about $A200 million to energy services company McDermott Industries – a subsidiary of J. Ray McDermott – for substructure and pipelay installation at the venture’s Angel gas platform.

Woodside awards $200m Angel jacket contract

The $A1.6 billion Angel development will be the venture’s third major offshore production platform. Located in 80m of water, the remotely operated Angel platform is expected to be fully operational by the fourth quarter of 2008.

The substructure and pipelay installation contract will involve transporting a 7500 tonne jacket and piles by J. Ray’s launch barge Intermac 650 from a fabrication yard in China to the offshore installation site, as well as the launch, upend and set-down of the jacket. One of J. Ray’s marine vessels will install the jacket and pipelines.

The offshore campaign will also involve installing a new subsea pipeline tied to the first trunkline about 49km west of the proposed Angel platform, and the installation of in-field flow lines.

The drilled and grouted jacket foundation requires installation of eight primary and eight secondary piles in holes up to 3m in diameter. J. Ray’s seasoned marine crew will install the 49km, 30-inch export pipeline and the three in-field 14-inch CRA pipelines using in-house automated welding systems.

J. Ray said the installation program had been timed so the jacket was installed before the cyclone season by the fourth quarter of 2007. The CRA pipelines and 30-inch pipeline installation will be completed during the first quarter of 2008.

“Our proven capability installing jackets with drilled and grouted foundations as well as pipelines, our extensive Australian experience, and ability to allocate world-class marine equipment provide the basis to make this project a success,” J. Ray’s Australian general manager Hugh Cuthbertson said.

“The scope of work set out by Woodside is ideally suited to the proven capabilities of J. Ray’s marine equipment and project management group.”

The project will be managed by J. Ray’s office in Perth, Australia, supported by its regional headquarters in Singapore. Installation engineering will be supported by J. Ray’s marine construction engineering group based in Dubai. The construction of drilling work decks, caissons and other items will be performed at the company’s Batam Island fabrication facility in Indonesia.
