Van Oord’s Nexus installed inter array cables Deutsche Bucht

Van Oord has installed more than 40 kilometres of inter array cables for the 269 MW Deutsche Bucht offshore wind farm, in the German Bight. The contractor used its cable laying vessel Nexus to perform the work.

Nexus installed the cables at 40 metres water depth, at a rate of up to three cables per 24 hours. Van Oord’s trencher Dig-It is now burying 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.

Balance of Plant
The inter array cable installation is part of a Balance of Plant contract. Van Oord was awarded the contract by Northland Power in  The responsibilities also include the design, engineering, procurement, construction and installation of the foundations and offshore substation, and the transport of the wind turbines. At the moment, Van Oord’s offshore installation vessel Aeolus has started turbine installation. Deutsche Bucht will feature 33 MHI Vestas’ V164-8.4 MW wind turbines with 80-metre rotor blades and a rated output of 8.4 MW. Commissioning of the wind farm is expected to take place in the second half of 2019. Source: Van Oord
