The business, formerly known as SgurrEnergy, will install 29 met masts and undertake data monitoring and analaysis of the site on Fosen Island.
Wood Group will then install power monitoring equipment on some of the turbines once they are installed for power curve testing.
The six-project cluster is due to be online in 2020.
It is being developed by a consortium led by Norwegian firm Statkraft, which had shelved the site in 2015, claiming it would be too expensive.
The site was revived by Statkraft in February 2016, with partners TronderEnergi and Nordic Wind Power.
Vestas is set to supply 278 Vestas V117 and V112 turbines, optimised to produce 3.6MW from 2018.
"[Power performance testing] allows you to compare the actual power curve for a wind turbine to the warranted power curve provided by the wind turbine manufacturer, and to ensure that the manufacturer corrects any sources of underperformance," said Wood Group's director of asset management Robbie Gibson.
French cable supplier Nexans was awarded the deal to supply 200 kilometres of 36kV cable to the first phase of the cluster, already under construction.
