Woodside Petroleum Ltd., Perth, has let four contracts for the front-end engineering and design phase of its proposed Scarborough gas development on the Exmouth Plateau off Western Australia.

McDermott Australia Pty. Ltd. was let a contract to undertake engineering studies for the floating production unit. This includes the option to progress to an engineering, procurement, and construction contract for the execute phase activities.

Subsea Integration Alliance, a consortium of OneSubsea Australia Pty. Ltd. and Subsea 7 Australia Contracting Pty. Ltd., has been let the contract to undertake engineering studies for subsea umbilical risers and flowlines. This also contains the option to progress to a next stage engineering, procurement, construction, and installation contract.

The third contract has been let to Saipem Australia Pty. Ltd. for provision of export trunk line engineering support services with the option to execute line pipe coating and installation activities.

The fourth contract has been let to Intecsea Pty. Ltd. for export trunk line engineering.

Woodside Chief Executive Officer Peter Coleman said the Scarborough project schedule targets a final investment decision in 2020.

The company’s preferred concept for development of the 7.3-tcf (2C) Scarborough gas resource is through offshore facilities connected by a 430-km export pipeline to the Burrup Peninsula and expanded onshore processing facilities at the Pluto LNG plant.

The proposed offshore development will comprise 12 subsea production wells tied back to a semisubmersible platform moored in 900 m of water close to the field.

The field, which lies in 950-1,400 m of water, was discovered in 1979 by a partnership of ExxonMobil Corp. and BHP Petroleum.

Woodside now has a 75% interest in Scarborough field following the $444-million acquisition of ExxonMobil’s interest in March 2018.
