Woodside Petroleum Ltd., Perth, has let a contract for define phase engineering services for the main trunkline to shore in its proposed Scarborough gas field development on the Exmouth Plateau off Western Australia to fellow Perth company Subsea Engineering Associates Pty. Ltd. (SEA).
SEA said the company will use its ICE Platform to ensure rapid delivery of engineering and a mature digital basis of design that can be carried into the project’s front-end engineering and design phase.
SEA has subcontracted another Perth company, Intecsea Pty. Ltd., to provide specialized deepwater experience for the project.
This follows an earlier Woodside contract to international seabed survey company Ocean Infinity Ltd. in June for provision of seabed data in support of the Scarborough development (OGJ Online, May 25, 2018).
That contract involves deepwater geophysical preengineering route survey extending from Scarborough field in 950-1,400 m of water, up the scarp towards the existing onshore domestic gas and LNG processing facilities on the Burrup Peninsula near Karrartha.
Scarborough lies 375 km west-northwest of the Burrup.
The proposed 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 contains an estimated 7.3 tcf of dry gas and was discovered in 1979 by the ExxonMobil-BHP Petroleum partnership.
Woodside now has a 75% interest in Scarborough field following the $444-million acquisition of ExxonMobil’s interest in March.
