Ecowende installs the first of 52 wind turbines

On 30 May, Ecowende installed the first of 52 Vestas V236-15.0 MW wind turbines around 53 kilometres off the coast of IJmuiden.


The project aims to combine offshore wind development with ecological innovation through the use of red turbine blades. A single red-painted blade, in contrast to the usual grey rotors, will be used to test whether a contrasting colour improves visibility for birds and reduces collision risks.


Additional measures include bird corridors between the coastline and the Natura 2000 site De Bruine Bank, with wider turbine spacing to allow seabirds to pass safely beneath the rotor sweep.


Ecowende will assess the success of the initiative using thermal and daylight cameras, impact sensors and bird radar systems.

The turbines are being installed through a partnership between Vestas and Van Oord. Vestas manufactures the turbine components and oversees transport and pre-assembly, while Van Oord installs them using the
Boreas, a multipurpose offshore wind turbine installation vessel.

This marks the first installation of its kind for offshore wind development in the North Sea. Each of the 52 turbines is rated at 15 MW, with the Ecowende wind farm expected to supply 760 MW to the Dutch electricity grid, supporting the Netherlands’ transition to renewable energy.
