Owned and developed by Vattenfall, the wind farm is located 15km off the coast of Denmark in the Baltic Sea. The installed foundation weighs 8,000 tonnes and it was floated off of a semisubmersible barge and towed to the installation location.
The heavy lift vessel Rambiz, in combination with an in-house designed ballast module had installed the foundation piece in place.
The second foundation which weighs 10,000 tonnes will be installed soon, depending on the weather conditions, stated the company.
Once all the foundations have been installed, Jan De Nul's multipurpose vessel Adhémar de Saint-Venant will begin with the ballasting and scour protection works.
The two foundations were constructed by Jan De Nul Group on a barge at the Port of Ostend in Belgium.
Jan De Nul has partnered with Smulders to construct the two foundation for the high voltage station of the wind farm.
The offshore wind farm, which will be built with a total estimated cost of €1.3bn, is due to come online by 2022 and will feature at least 72 of Siemens Gamesa’s 8MW wind turbines.
The wind farm consists of two parts, with 200MW Kriegers Flak A in the west section and the 400MW Kriegers Flak B in the east.
When completed, the wind farm is expected to generate enough clean electricity to be supplied to more than 600,000 Danish households.
In November 2016, Vattenfall had won a tender to build the Kriegers Flak offshore wind farm in Danish waters with a record low bid of EUR 49.9 per MWh.
In March 2017, the European Commission had given its consent for Denmark to support the 600MW Kriegers Flak offshore wind farm as it complied with EU state aid rules.
