Layer of Stones to Protect Connection Cables at Danish Offshore Wind Farm

On Wednesday 19 June 2013 around noon, DONG Energy’s technicians confirmed that the last of the 111 wind turbines in Anholt Offshore Wind Farm had just been connected to the power grid and could thus send its first CO2-free electricity to shore to the Danish power grid.

The 111 wind turbines in the wind farm are connected with Energinet.dk’s offshore substation via approximately 160 kilometres of cable flushed down into the seabed. However, at several positions, it has not been possible to flush the cable at a sufficient depth due to stones or hard seabed.

Therefore, the vessel, Tertnes, will lay a protecting layer of stones in the identified areas during the summer to ensure the required protection of the cables.
