Almost two years after construction of Hollandse Kust Zuid began, the last turbine of the 1540MW Dutch offshore wind farm has been installed, Vattenfall has announced.
In the coming months, the interior of the turbines will be further completed and tested.
The development is expected to become officially operational later this year.
Project director Ian Bremner said: “We are immensely proud of reaching this milestone.
“The installation of the last turbine is a key moment for the project, not only for us, but also for our partners and all the suppliers and contractors who helped us get here.
“Hollandse Kust Zuid is the world’s first subsidy-free offshore wind farm and we look forward to delivering this project.”
Siemens Gamesa’s managing director in the Netherlands David Molenaar added: “Today we are celebrating the final installation of our biggest-ever offshore project.
“The nacelles were manufactured at our factory in Cuxhaven in Germany and the blades came from Aalborg, Denmark.
“This project once again underlines how the wind industry can offer Europe energy security through its own, clean and competitive sources.”
Siemens Gamesa was supported for the transport and installation of all 139 offshore wind turbines by Cadeler’s Wind Osprey vessel.
The total number of turbines is one less than the 140 originally planned.
Last year, one of the foundations was damaged after a collision with cargo ship Julietta D which lost power during a storm and drifted through the wind farm.The foundation was damaged so badly in the process that installing a full turbine at this location is not considered responsible.
After consultation with partners, contractors and the authorities, it was decided not to replace the foundation and to remove it in 2024.As yet, there are no concrete plans for the vacant space.
