Smulders and Jan De Nul Group joined forces to build two Gravity Based Foundations (GBFs) for the high voltage substation of the Danish Offshore Wind Farm Kriegers Flak. Both foundations consist out of a concrete part (GBF) and a steel structure on top. Jan De Nul Group 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.
On 17-18 March 2018, the first Gravity Based Foundation of 8,000 tonnes was installed in Denmark, an important milestone in this project. The installation of the second foundation of 10,000 tonnes will occur as soon as possible.
About the wind farm
The Danish wind farm 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 200 MW. The east section, Kriegers Flak B, will have a total capacity of 400 MW. Each section will dispose of its own substation, serving both for the future Krieger Flaks offshore wind farm as well as an interconnector between the Danish and German power net.
By 2022, Denmark's to date largest offshore wind farm will start generating CO2-free electricity for approx. 600,000 households. The interconnector project is funded by the European Energy Programme for Recovery.
