French conglomerate installs power cables to Scotland’s largest offshore wind farm

Nexans’ cable-ship sets sail for Moray Firth wind farm installation

The first of the two 400-kV onshore cable links and high voltage accessories to the 588-MW Beatrice offshore wind farm in the Moray Firth have been successfully installed and tested on site.

At the same time, the Nexans factory in Norway has completed manufacture of the 220-kV offshore cable and loaded the final section onto the Group’s Skagerrak cable laying vessel for the journey across the North Sea to the Moray Firth, where it will be installed and later trenched into the seabed.

To export the energy from the wind farm to the grid, the two offshore cables take a route of 70 km along the seabed to a landfall point to the west of Port Gordon on the Moray coast. A transition joint bay then connects them to the onshore cable system, which takes a 20 km route to Blackhillock substation. From there, the 400-kV onshore cables will transmit the electricity to the grid.

The Beatrice windfarm, scheduled to be fully operational by 2019, is a joint venture between SSE, Copenhagen Infrastructure Partners and Red Rock Power Limited –  the UK subsidiary of China’s SDIC Power Holding Co.

Located in the Moray Firth, it will be Scotland’s largest wind farm, with the combined output of 84 turbines capable of generating enough electricity to power approximately 450,000 homes.
