Kriegers Flak finds it feet

In: VesselsWindfarms
Van Oord’s heavy lift vessel Svanen has installed the final foundation for the Danish Kriegers Flak offshore wind farm in the Baltic Sea, ahead of schedule.

A total of 72 monopiles were transported floating from Rostock, Germany, directly to the offshore site. The transition pieces were transported on barges from Aalborg, Denmark. Vattenfall awarded the transport and installation of the foundations for Kriegers Flak Offshore Wind farm to Van Oord.

During execution, all safety - and COVID-19 restrictions were in place, creating a safe work environment for those involved. Van Oord’s fleet for this project consisted of 10 vessels, in order to carry out all works. To reduce the underwater noise a ‘double big bubble curtain’ was used during pile driving. The project team worked closely with Vattenfall and foundation suppliers EEW Group and Bladt Industries to deliver this project.

Ian Bremner, Project Director at Vattenfall, commented: "With the last foundation successfully installed, one of the most important milestones in the success of the Danish Kriegers Flak Wind farm is achieved. The Svanen and the associated fleet have delivered excellent results. We are very pleased with the cooperation and continuous good spirit."

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 scheduled to be fully operational in 2021.
