Jan De Nul: Another Milestone for Kriegers Flak
The first Gravity Based Foundation for the offshore wind farm Kriegers Flak was installed in Denmark this weekend, marking another milestone in this project, Jan De Nul said in its latest release.
It concerns a 8,000 tonnes GBF which was floated off the semisubmersible barge and towed to the installation location, where the heavy lift vessel Rambiz in combination with an in-house designed ballast module set the structure down onto the seabed.
The second GBF, weighing 10,000 tonnes, will be installed as soon as possible, depending on the weather conditions, Jan De Nul said.
Once the foundations have been installed the most recent multipurpose vessel of Jan De Nul, Adhémar de Saint-Venant, will start with ballasting and scour protection works.
Both foundations were constructed by Jan De Nul on a barge in the Port of Ostend in Belgium. The barge was towed to Denmark on 8 January, 2018.
