The first installation campaign for Parkwind’s 257MW Arcadis Ost 1 wind farm has successfully finished.
The foundation installation began in the early summer of 2022, before the wind turbine installation began at the end of 2023.
Arcadis Ost 1 has already been delivering green energy to the German grid since mid-January 2023.
The installation of Arcadis Ost 1 marked the first wind farm construction in the Baltic Sea after a three-year break in new wind farm installations.
This marks the end of the first installation campaign of the wind farm using the floating installation method developed together with Heerema Marine Contractors and Vestas.
However, Vestas incurred delays on the deliveries of some rotor blades.
The remaining three turbines will be installed upcoming Autumn, completing the wind farm.
The Rotor Nacelle Assembly (RNA) method has proven to be a successful and reliable method for installing wind turbine generators with floating installation vessels, Heerema said.
Installation cycle times were consistent and competitive with traditional methods while the floating installation introduces various specific benefits, such as zero seabed interaction which is especially important in areas of significant water depth or challenging soil conditions, it added.
Ramon de Haas, chief technology officer of Heerema said: “The floating installation of Arcadis Ost 1 has demonstrated Heerema’s ability to make a real change in the offshore wind market.
“We continue to be committed to introducing new methodologies that can solve industry challenges.”
Co-chief executive of Parkwind Eric Antoons said: “The success of the RNA installation method marks a significant achievement for the offshore wind industry.
“Parkwind has been at the forefront of innovation in offshore wind for the last decade, and with Arcadis Ost 1 we continue to do so.
“As offshore wind energy targets grow, this kind of innovation is key if we want to move towards a sustainable future as fast as possible.
“As zones go further offshore and turbines increase in size, we are certain to see a continued demand for substantial innovation in our industry. We are delighted to be a part of this journey.”
