37 km offshore cable will connect NnG to onshore substation

#wind energy – Neart na Gaoithe

The first of two export cables, each 37 kilometres in length, has been installed at the nearshore of Thorntonloch Beach as part of construction of the Neart na Gaoithe (NnG) Offshore Wind Farm.

These electricity transmission cables will connect NnG’s two offshore platforms to its onshore substation located in the Lammermuir Hills.

The offshore cable was transported to the nearshore area of Thorntonloch Beach by Prysmian Group’s cable-laying vessel, Cable Enterprise.

The onshore winch cable was pulled through a 650m long horizontal directional drill duct and connected to the offshore cable situated on the deck of the vessel, 1km from shore.

The offshore cable was then directed back through the duct towards onshore where it will be connected to the onshore cables behind Thorntonloch Beach.

The Cable Enterprise will lay the offshore cable from the nearshore of Thorntonloch Beach to the site of NnG. The cables will be buried to protect them from damage. Prysmian, one of NnG’s tier one contractors, expect the second offshore cable to be installed in July.
