“Certification confirms that Kriegers Flak wind farm is in compliance with Danish regulations and that the safety of the wind farm is ensured”, said Liana Tatar, the responsible project manager at TÜV SÜD.

TÜV SÜD’s contract covered certification of the design of the foundation structure as well as surveillance and certification throughout the manufacturing, transport, installation and commissioning phases in accordance with BEK 73 (Executive Order from the Danish Ministry for Climate, Energy and Buildings, No. 73).

Within the scope of certification, TÜV SÜD’s offshore wind energy experts examined the design of the wind turbines’ monopile foundations and their connections to the towers by means of a transition piece, the certification company said.

Design examination of the foundations started in summer 2018. The project certificate was handed over to Vattenfall in early September 2021.
