Foundations for the Danish offshore wind farm Kriegers Flak are on their way to the site from Port of Ostend.

Transportation of foundations

The foundations for Kriegers Flak are being transported by a barge towed by the tug 'Zeus of Finland'

The two Gravity Based Foundations (GBFs) weighing 10,000t and 8,000t are being transported by a barge towed by the tug Zeus of Finland and are expected to arrive at the site, located in the Baltic Sea off Denmark, on 15 January.

Designed for the farm’s high voltage station, the foundations consist of a concrete part (GBF) and a steel structure on top.

Installation

Jan De Nul Group was responsible for the design and construction of the concrete GBF, while Smulders designed and constructed the steel shafts and decks placed on top. Jan De Nul Group is now in charge of the installation of both GBFs, the ballasting and the placement of scour protection.

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 multipurpose vessel Adhémar de Saint-Venant will start ballasting and scour protection work.

The farm 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.

Significant output

Each section will dispose of its own substation, serving both the wind farm and an interconnector between the Danish and German power net.

By 2022, the farm is expected to start generating CO2-free electricity for approx. 600,000 households.

The interconnector project is funded by the European Energy Programme for Recovery.
