The work is part of a contract awarded to McDermott by Woodside Energy in January 2016 for GWF Phase 2 project, which is expected to commence production by the end of this year.

Under the contract, McDermott was responsible for the procurement, fabrication, installation and testing of a series of pipeline buckle initiators, pipeline end terminations and foundation mudmats, in-line tee structures and approximately 35km of a 16-inch corrosion resistant alloy (CRA) pipeline.

The CRA pipeline extends from the existing Goodwyn A Platform to the Lady Nora and Pemberton field manifold locations.

McDermott Asia Pacific senior vice-president Ian Prescott said: “McDermott’s strong execution capability is one of the reasons why clients continue to entrust their most important projects to us.

“Greater Western Flank 2 is a testament to our execution, preparation and vertical integration capabilities. It shows McDermott can deliver challenging projects in challenging environments.”

For the installation phase, McDermott used two specialty vessels including DLV 2000 for the pipelay campaign and the Lay Vessel 108 for the pre-lay and post-lay campaign.

In order to simulate the offshore installation campaign, the firm has launched an onshore portable and temporary double jointing facility at its Batam fabrication yard in Indonesia.

McDermott GWF-2 project director Vince Vieraitis said: “One of the key challenges of the project was to perform installation work inside the 546 yards (500 meters) safety zone of Woodside’s Goodwyn A Platform.

“Through close collaboration with the client, the project was delivered in full compliance to project specifications with zero lost time incidents.”

The Greater Western Flank Phase 2 project includes the development of eight wells from the Keast, Dockrell, Lady Nora, Pemberton, Sculptor and Rankin fields.

Woodside Energy will operate the development on behalf of a joint venture of BHP Billiton Petroleum, BP Developments Australia, Chevron Australia, Japan Australia LNG (MIMI), and Shell Australia.
