Installation Kriegersflak topsides in Baltic Sea

The Kriegersflak substations that Hollandia Offshore built in cooperation with main subcontractor Croonwolter&dros for Energinet.dk, have arrived, right on schedule, at their final destination in the Baltic Sea. Scaldis succesfully installed the topsides on the foundations, which were placed by Jan de Nul earlier this year. These coming weeks, hook-up activities will take place.

The substations KFA, KFB en KFE are part of Kriegersflak Vattenfall's 600 MW Wind Farm in the Danish sector of the Baltic Sea. The wind farm consists of two sections, each with its own substation.

KFA will be installed in the west section of the wind farm and will have a total capacity of 200MW. The east section, KFB, will have a total capacity of 400MW. KFB substation will also serve as the support for the KFE module and be part of the so-called Combined Grid Solution project run by Denmark’s Energinet.dk and the German transmission systems operator 50 Hertz.

The Combined Grid Solution will interconnect the Danish and German grid via two offshore wind farms, Kriegers Flak and Germany’s Baltic 2 and Baltic 1. In a later stage, the Swedish high-voltage network can also be connected. The Combined Grid Solution project is funded with up to EUR 150 million from the European Energy Programme for Recovery.

Hollandia Offshore and Denmark’s Energinet.dk signed a contract for the engineering, procurement and commissioning of the substations in May 2016. Subcontractor Croonwolter&dros is responsible for the design, procurement and installation of the utility systems such as the low voltage systems, the fire fighting systems and the HVAC.
