Fugro is undertaking nearshore surveys for SSEN Transmission’s Western Isles High Voltage Direct Current (HVDC) Link, a project that will enable the transfer of 1,800 MW of renewable energy from Scotland’s islands to the UK mainland. The surveys will provide geodata to inform the design of cable landfalls, helping reduce risk and optimise route planning.
The link – comprising around 83km of underground cable and 81km of subsea cable – will connect the Isle of Lewis to the mainland, supporting the efficient transmission of renewable power and strengthening the UK’s electricity network.
Fugro is combining geophysical mapping with geotechnical boreholes to build a detailed understanding of seabed and coastal conditions, using the specialist ARAN® 250 jack-up platform. Work has focused on sites near Arnish Point and Dundonnell, with sampling designed to minimise environmental impact. Laboratory analysis of soil samples will provide insights to support design and construction, with survey work progressing at Dundonnell.
“We welcome Fugro’s progress in delivering nearshore surveys for our Western Isles HVDC Link, which will connect the Western Isles to the GB Transmission network for the first time. These surveys are another step forward in progressing the project. We’d like to thank everyone who had contributed to the marine consultation events that have helped inform our potential cable landfall sites for the project, which this survey work is helping to progress.” Niall MacLeod, Project Director for SSEN Transmission
“Our integrated approach, combining specialist platforms, expert teams, and advanced laboratory analysis, will give SSEN Transmission the reliable Geo-data needed to make informed engineering decisions and help deliver clean, secure energy to communities across the UK safely and sustainably.” Matthew Chappell, Fugro’s Regional Service Line Director for Nearshore
