VSMC, a joint venture between Royal Boskalis Westminster and VolkerWessels, will complete the export and inter-array cables at the 400MW project off England's east coast.
The first work will be the creation of two 1,100-metre horizontal directional drillings at the landfall. The export cables, stretching 42 kilometres to the coast, are expected to be installed in 2016.
Included in the work is the design, supply, installation and testing of the 67 infield cables with a total length of around 100 kilometres.
Statoil and Statkraft announced their final investment decision to go ahead with the construction of the project earlier this week. The total investment in the wind farm is expected to be £1.5 billion (EUR 1.9 billion).
It will be made up of 67 of Siemens' SWT-6.0-154 6MW turbines.
