First wind turbine installed in Hollandse Kust Zuid

The first turbine of the Hollandse Kust Zuid offshore wind farm was installed over the Easter weekend. With good visibility, the wind farm can now be seen from the coast.

The installation of the first turbines started with the loading of the turbine components from the quay on the Maasvlakte. The installation vessel Wind Osprey from Cadeler loaded parts for four turbines on board: four masts, four turbine nacelles and twelve turbine blades.

Søren Andersen, Senior Turbine Installation Package Manager at Vattenfall:

“With the arrival of the Wind Osprey in the week of April 12 and the loading of the turbine components, the first installation could start on April 16. The vessel will take four wind turbines on board each trip, with the goal of having all turbines installed by 2023. It is great to see how all the plans come together and how we shape the energy transition with the installation of these gigantic turbines. It is an absolute honor to be able to play a role in the transition to a fossil-free future,” he says.

Installation of foundations and cables continues

At the same time the second phase of the construction project has started after the winter break. In all, 140 turbines are to be installed. Now the piling of the remaining 104 foundations will commence. Seaway's vessel Strashnov will carry and install three foundations at a time while the Jumbo ship Fairplayer will place the platform on the foundation after the foundation has been installed. This summer, all foundations will be anchored to the North Sea bed.

The Hollandse Kust Zuid wind farm is being built by Vattenfall and is owned by Vattenfall, BASF and Allianz.
