Siemens Gamesa and Van Oord consortium Zuiderzeewind has finished installing the turbines at the Fryslan offshore wind project in the Netherlands.
After installation at the site on the Ijsselmeer, each of the 89 4.3MW wind turbines will be inspected from foundation to nacelle, then tested before being put into operation.
Since the first wind turbines started running in April, Windpark Fryslan has been supplying energy to Eneco customers.
When all wind turbines are in operation, they will produce about 1500 gigawatt hours of wind energy on an annual basis.
Each wind turbine consists of three tower parts, the nacelle and the rotor.
Due to the limited width of the locks around the IJsselmeer, the parts were brought to the IJsselmeer by ships and assembled there.
Two installation platforms, the Sarens Soccer Pitch and the Tom-Wim, were located in the IJsselmeer.
By working with two platforms, Zuiderzeewind was able to install two wind turbines at the same time.
Fryslan is being built by the contractor consortium Zuiderzeewind, which consists of Siemens Gamesa and Van Oord Offshore Wind.
