Royal Boskalis Westminster has won a contract for seabed intervention and shore crossing activities for Woodside’s proposed Scarborough export gas pipeline in Australia.

The contract, which was awarded by Woodside Energy, is potentially worth €145 million if all options are included. It is subject to a final investment decision, which is expected in 2020.

The seabed intervention and shore crossing works are due to begin in March 2021, with an expected completion date in mid-2022.

The scope of work to be carried out under the contract includes the pre-trenching of the nearshore pipeline route for a distance of 50km, offshore deepwater excavation works, pre-lay and post-lay rock installation for pipeline and fibre optic cable crossings, post-installation burial and other protection works for pipeline stability.

Boskalis will use in-house specialist expertise and equipment including a trailing suction hopper dredger, a backhoe dredger, a dynamically positioned fallpipe vessel and rock installation vessel, survey vessels and an offshore construction vessel.

The Scarborough gas field is located around 375km offshore the Burrup Peninsula in North West Australia. The proposed pipeline will transport natural gas from a floating production unit at the Scarborough field to an onshore processing plant.
