The contract was awarded by CT Offshore, which is to install 63 of the 161 interarray cables at the project.
CWind will send a team to the Netherlands to perform both an optical time-domain reflectometer fibre test and an insulation resistance test on the cable at load-on.
During installation, CWind workers will pre-rig towers prior to the arrival of the installation vessel to speed up installation times, and pull in the cables at both ends.
Cwind has provided cable pulling and repair support at several UK offshore wind farms, including Barrow, Greater Gabbard, Lincs, Ormonde, Thanet, Walney 1 and West of Duddon Sands.
The project is made up of 160 Siemens 3.6MW turbines, with some of the machines already generating power.
