The project milestone marks a series of firsts for the offshore wind industry.

Firstly, these will be the first wind turbines ever to be installed on a subsidy-free offshore wind farm seeing that Vattenfall is constructing Hollandse Kust Zuid without financial assistance from the Dutch government.

Secondly, these Siemens Gamesa 11 MW wind turbines will be the largest and the most powerful commercial wind turbines to be installed on any wind farm in the world. The wind turbines have a rotor diameter of 200 metres and a total height from sea level to the top of the blade of 225 metres.

And thirdly, this marks the start of the turbine installation phase on what will become the largest offshore wind farm in operation once commissioned in the summer of 2023.
