Kriegers Flak foundations depart Ostend

Jan de NulThe two foundations for the Kriegers Flak offshore wind farms substation platform have left the port of Ostend in Belgium aboard a transportation barge.

The barge is being towed by a tug and is planned to arrive in Denmark on the 15th of 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 Nuls multipurpose vessel Adhémar de Saint-Venant will start ballasting and scour protection works.

Jan De Nul Group and Smulders joined forces to build the two Gravity Based Foundations (GBFs) for the high voltage station of the Danish offshore wind farm Kriegers Flak.

The two foundations, weighing 10,000 tonnes and 8,000 tonnes, consist of a concrete base (GBF) and a steel structure on top. Jan De Nul Group was responsible for the design and construction of the concrete GBF, while Smulders tookk care of the design and construction of 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 at the Kriegers Flak offshore wind farm in Denmark.

The Danish project is located in the Baltic Sea and will consist 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 funded by the European Energy Programme for Recovery.

Siemens Gamesa  Renewable Energy recently announced that as part of the worlds largest turbine order with Vattenfall they will be supplying 72 of their new SG 8.0-167 DD turbines which have a rotor diameter of 167m for the project.

Construction permission for the Danish part of the Kriegers Flak was granted to Vattenfall in November 2016 with a winning bid of EUR 49.9 per MWh. Financial close is expected in Q2 2018 with commissioning of the 600MW project expected in 2021. On track to be Denmarks largest wind farm, the project will generate CO2-free electricity for approx. 600,000 households.
