January 2017 saw the start of the installation of the underground cable link between landfall (near Portgordon) and the substation at Blackhillock.
Two large pipes were installed under the beach at Portgordon through which the export cables pass.
The installation of around 20km of underground cable is complete, some of which was installed utilising horizontal directional drilling techniques which enabled the cables to be laid under obstacles such as roads, water courses and sensitive habitats.
Nexans, the main contractor, has employed Murphys to undertake the civils aspects of these works.
The cable route is being reinstated during summer 2018.
The first stage of installing the onshore cables was to mark out the cable route and to install fencing to create safe working zones.
Access points were created or, where possible, existing access was used.
Trenching was then dug into which the ducting will be laid.
Horizontal directional drilling (steerable drilling) was used to bypass some obstacles such as roads, rail and rivers with the minimum of disruption.
Once the ducting was laid, protective boards and marking tape was placed over and the trench was backfilled.
The export cables were pulled through the ducting.
