Kriegers Flak GBFs Leave Port of Ostend

Kriegers FlakOn Monday 8 January, a barge with two impressive foundations of 10,000t and 8,000t, destined for the Danish offshore windfarm Kriegers Flak, left the port of Ostend in Belgium.

The barge, that is is towed by the tug Zeus of Finland, is planned to arrive in Denmark on 15 January 2018. Depending on the weather conditions, the first foundation will be installed by the end of January, and the second a couple of weeks later. Once the foundations have been installed Jan de Nul’s Adhémar de Saint-Venant will start with the ballasting and scour protection works of the foundations.

Jan De Nul Group joined forces with Smulders to build the two gravity based foundations (GBFs) for the high voltage station of the Danish offshore windfarm Kriegers Flak. Both foundations consist of a concrete part (GBF) and a steel structure on top. Jan De Nul was responsible for the design and construction of the concrete GBF, while Smulders took care of the design and construction of the steel shafts and decks, placed on top.

Jan De Nul is now in charge of the installation of both GBFs, the ballasting and the placement of scour protection. The windfarm Kriegers Flak, located in the Baltic Sea, will consist out of two parts. Kriegers Flak A, the west section, will have a total capacity of 200MW. The east section, Kriegers Flak B, will have a total capacity of 400MW. Each section will dispose of its own substation, serving both for the future Krieger Flaks offshore windfarm as well as an interconnector between the Danish and German powernet. By 2022, Denmark’s to date largest offshore windfarm will start generating electricity for around 600,000 households. The interconnector project is funded by the European Energy Programme for Recovery.
