Van Oord has installed more than 40 kilometres of inter array cables for the 269 MW Deutsche Bucht offshore wind farm. These cables form the connection between the turbines and the offshore substation. For the Deutsche Bucht project, Van Oord’s cable laying vessel Nexus installed a web of cables at 40 metres water depth.The vessel installed at a rate of up to three cables per 24 hours. To protect the cables, Van Oord’s trencher Dig-It has now been deployed to bury the previously laid cables to the required depth of 1.5 metres below the seabed. The remote-controlled trencher uses the jetting module. By injecting a high water flow, the soil is liquified enabling lowering of the cable. In the meantime, Van Oord’s offshore installation vessel Aeolus started turbine installation. Each turbine has three 80-metre rotor blades and a rated output of 8.4MW. Commissioning of the wind farm is expected to take place in the second half of 2019.
