The turbine will go through a five-year testing regime, according to the initial deal with developer Future Wind — a joint venture between consultancy Pondera and Sif Holding.
It has been installed close to Sif’s offshore turbine foundation plant at the Maasvlakte 2 extension of the Port of Rotterdam.
The Haliade-X is currently the largest turbine anywhere in the world, with 12MW of output and a 220-metre rotor. This demonstration machine has a hub height of around 135 metres, resulting in a tip height of 245 metres.
The turbine foundation is based on a four-metre high coning concrete slab with a 28-metre diameter, supported by 48 round piles, each measuring 65cm in diameter, according to project documents.
The US firm announced the completion of the prototype on social media.
