First foundation touches down at Kriegers Flak

Foundations General

The first foundation for Vattenfall’s Kriegers Flak offshore wind farm has been installed in the Baltic Sea. During pile driving, a double curtain of bubbles will be deployed around each foundation to mitigate noise as a safeguard for marine mammals.

Installation of the foundations is expected to run into the autumn this year, with installation of turbines starting in 2021. Despite restrictions following the COVID-19 pandemic, the development of Kriegers Flak is on schedule to be in full operation by the end of 2021, at the latest.

The monopile foundations have been manufactured by EEW-SPC in Rostock. On top of the foundations, transition pieces from Bladt Industries will be mounted to carry the 8.4 MW Siemens Gamesa turbines. The foundations will be transported and installed by Van Oord.

On the foundations, 72 turbines will be mounted to create Denmark’s largest offshore wind farm with a capacity to cover the annual electricity consumption of approximately 600,000 Danish households.

“The foundation represents the first visual offshore part of the wind farm itself. It’s a milestone in the development of this great project and Vattenfall’s journey towards enabling fossil-free living”, says Catrin Jung, Head of Offshore Wind, Vattenfall.

Located 15-40 km offshore in the Danish Baltic Sea, the Kriegers Flak wind farm is set to feature 72 Siemens Gamesa SG 8.0-167 DD turbines, each with a rotor diameter of 167 metres and tip height of 188 metres. Vattenfall secured rights to the 604.8 MW project in November 2016, with a winning bid of EUR 49.9 per MWh. The project is aiming to complete installation works for foundations and cables in 2020, and for the wind turbine installation process to begin in early 2021.

In order to facilitate construction works, Vattenfall will establish temporary construction facilities in Rødvig. The Port of Rønne, as the selected port of departure for turbines, has also been expanded by 150,000 square metres. Vattenfall plans to construct an operations and maintenance building in the harbour of Klintholm, to oversee the project's operational lifetime. Kriegers Flak is the latest and largest of Vattenfall’s recent offshore projects in Denmark. Others are Horns Rev 3, which was inaugurated last year, and Vesterhav Syd & Nord, which are scheduled to be in full operation by the end of 2023, at latest.
