McDermott International has completed the contract for phase two of the Greater Western Flank project (GWF), which was awarded by Woodside Energy in January 2016.

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 35 kilometers of a 40 centimeters corrosion resistant alloy (CRA) pipeline extending from the existing Goodwyn A Platform to the Lady Nora and Pemberton field manifold locations.

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

One of the key challenges of the project was to perform installation work inside the 500 meters safety zone of Woodside’s Goodwyn A Platform,” said Vince Vieraitis, McDermott’s GWF-2 project director. “Through close collaboration with the client, the project was delivered in full compliance to project specifications with zero lost time incidents.”

McDermott deployed two of its specialty vessels to complete the installation phase, namely DLV 2000 for the pipelay campaign and the Lay Vessel 108 for the pre-lay and post-lay campaign.

McDermott also set up an onshore portable and temporary double jointing facility at its Batam fabrication yard in Indonesia to simulate the offshore installation campaign.

The Greater Western Flank Phase 2 fields lie in water depths varying between 80 meters and 130 meters at approximately 40 to 60 kilometers southwest of the Goodwyn A Platform, located off the northwest coast of western Australia.

It includes the development of eight wells from the Keast, Dockrell, Lady Nora, Pemberton, Sculptor and Rankin fields. Gas production is tied-back via the pipeline end termination, in-line tees and subsea pipeline to the platform.

The project is expected to achieve first gas by the end of this year.
