Kriegers Flak Offshore Substation Topsides Start Rolling Out

Hollandia Offshore and Croonwolter&dros have moved the Kriegers Flak B (KFB) offshore substation topside from Hollandia Offshore’s production hall in Krimpen aan den IJssel and into the yard.  

The Kriegers Flak A (KFA) topside is scheduled to be rolled out into the yard on Thursday, 23 November, with Sarens managing the site moves.

Fridus Rijnten, Commercial Manager of Hollandia Offshore, said: “The roll out marks the start of the final phase of the outfitting of the topsides. I  would like to compliment the full team with this achievement and I’m looking forward to celebrate the next milestone.”

The topsides will remain at the yard’s assembly square for outfitting until the load-out early spring next year, Holandia Offshore said.

“The operation was done safely, according to schedule, and as per procedure. Great coorporation between our Yard Management and our subcontractor Sarens,” Julien Mos, Project Manager, said.

The Kriegers Flak substations will be installed on Vattenfall’s 600MW 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.

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 Energinet signed the 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.
