SSEN Transmission is set to begin nearshore marine survey work off north-west Shetland for the proposed Shetland 2 HVDC Link.
The company said the surveys will gather data on seabed and coastal conditions near Braewick, a potential landfall site for the subsea cable.
SSEN Transmission added that the location could connect via an underground cable route to a proposed Northern Substation Hub in mainland Shetland.
The work forms part of a wider marine survey programme to inform the final design, route and landfall location.
A Notice to Mariners will be issued detailing vessel activity and timings during the surveys.
The Shetland 2 HVDC Link would provide a second connection between Shetland and the Scottish mainland and support energy security.
“Marine surveys are an important early step in assessing potential landfall locations for the subsea cable, and the upcoming work off the coast at Braewick will help us better understand the area’s suitability,” said David Inge, development portfolio manager at SSEN Transmission.
“We would like to again thank everyone who attended and provided feedback at the consultation events held in 2025, and we look forward to continued engagement with local communities and stakeholders as we progress and shape our proposals.”
