Caithness - Moray HVDC Link - Route Clearance & Survey

The Caithness - Moray HVDC Link will be a twin bundled High Voltage DC interconnector (single cable diameter 132mm) installed by ABB HVC for Scottish Hydro Electric Transmission (SHE T) stretching approximately 113 km across the Moray Firth from Portgordon in Moray to Noss Head in Caithness.

During 1st quarter 2017, ABB will undertake route preparation and survey operations along the Route.

The Siem Ruby will be used to tow the SCAR plough and carry out an ROV survey of the cleared route.

In nearshore waters (6m - 15m) at Portgordon the multicat C-Odyssey will assist the Siem Ruby in its route preparation and survey operations.

There is a working area 250m either side of the cable route centreline coordinates given by the Route. Seafarers are requested to keep clear during these operations.
