Svanen uses bubbles to silently install offshore foundations in Denmark

Van Oord

PRESS RELEASE – Van Oord’s heavy lift vessel Svanen has installed the final foundation for the Danish Kriegers Flak Offshore Wind farm in the Baltic Sea. To reduce the underwater noise, a “double big bubble curtain” was used during pile driving.

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. The contract for the transport and installation of the foundations for Kriegers Flak Offshore Wind farm was awarded to Van Oord by Vattenfall.

The Svanen installed all of the monopiles ahead of schedule. 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 ten vessels.

Kriegers Flak Offshore Wind farm

With a production capacity of just over 600 MW, Kriegers Flak will be Denmark’s largest offshore wind farm and is scheduled to be fully operational in 2021. When the wind farm is in full production, it will increase the yearly Danish electricity production from wind by 18 per cent equivalent to roughly 600,000 Danish households’ annual electricity consumption. The wind farm is being constructed in the Baltic Sea and will be located between 15 and 40 kilometres from the Danish coast.

Immediately if you buy a new house, you will observe that you need a new set of sofa to make your house complete. If that is the case, you don’t have to buy a new one. Instead, look for a Sofa Reupholstery professional. Like Cotton Ware who offers a very good quality sofa re-upholstery service, Curtain Singapore.
