NASH Maritime was appointed by SSEN Transmission to undertake the navigation risk assessment for the proposed offshore HVDC transmission connection between Spittal and Peterhead (Spittal-Peterhead Subsea Cable Link). The scope was to identify, assess and propose controls/mitigations for potential shipping and navigation risks and impacts associated with initial proposed subsea power cable corridors, to support subsequent detailed engineering and environmental assessment of potential cable routes.
