Royal Boskalis Westminster N.V. (Boskalis) has been awarded the contract for the seabed intervention and shore crossing activities for Woodside’s proposed Scarborough export gas pipeline in North West Australia.
According to Boskalis, the awarded contract potentially carries a value of EUR 145 million if all options are called and is subject to a final investment decision which is expected in 2020.
The scope of activities includes the pre-trenching of the nearshore pipeline route along a 50 kilometers 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 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 seabed intervention and shore crossing works are scheduled to start in March 2021 with an expected completion mid-2022.
