Selecting the offshore cable route

The North Sea Link cable route will run from Kvilldal, in South West Norway, to East Sleekburn, on the Northumberland coast, passing through Norwegian and British waters.

A desktop cable routing study and detailed offshore survey was undertaken to determine the optimum route, and an Environmental Report has been prepared.

The environmental impacts of this route have been assessed and an Environmental Report has been prepared.

A seabed survey was carried out using non-intrusive methods (geophysical) and intrusive methods (geotechnical) to provide information on the seabed type, for both engineering and environmental purposes.

The cables will be buried between 1m and 3m into the seabed using a range of installation techniques suited to the seabed conditions.
