Kriegers Flak Substation Topsides Hit the Water

Hollandia Offshore and Croonwolter&dros have loaded two out of the three substation topsides built for the Kriegers Flak project onto a barge.

The Kriegers Flak B (KFB) and the Kriegers Flak E (KFE) topsides have been loaded onto a barge at Hollandia Offshore’s production hall in Krimpen aan den IJssel and will sail away on Monday evening, 23 April.

The Kriegers Flak A (KFA) topside is scheduled to be loaded out on Tuesday, 23 April, and will start its journey towards the Danish Baltic Sea on 29 April, Julien Mos, Project Manager, told Offshore WIND.

The project is proceeding according to the schedule and to the client’s satisfaction, Mos said.

The KFA and KFB substations will be installed on Vattenfall’s 605MW Kriegers Flak 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. Jan De Nul installed the foundations for the substations earlier this year.

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 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 288MW Baltic 2. 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 signed a contract for the engineering, procurement and commissioning of the substations in May 2016. Croonwolter&dros, Hollandia Offshore’s partner on the project, 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.
