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

The contract awarded by Woodside Energy, in its capacity as operator of the Scarborough Joint Venture, potentially carries a value of €145 million (US$160 million) if all options are called and is subject to a final investment decision which is expected in 2020.

The preparatory activities for this multi-disciplinary project have commenced recently. The seabed intervention and shore crossing works are scheduled to start in March 2021 with an expected completion mid-2022.

The scope of activities includes the pre-trenching of the nearshore pipeline route along a 50-kilometre section, offshore deep water excavation works, pre-lay and post-lay rock installation for pipeline and fiber optic cable crossings, the post installation burial, and other protection works to ensure the stability of the pipeline.

Support for the shore crossing to the onshore processing facility on the Burrup Peninsula as well as rock supply are also part of the contract.

Boskalis will deploy a wide variety of its in-house equipment including a trailing suction hopper dredger, a backhoe dredger, a DP fallpipe vessel and rock installation vessel, survey vessels, and an offshore construction vessel.
