For, Hollandia Offshore together with subcontractor Croonwolter & dros built the Kriegers Flak substations. Jan de Nul Group provided the foundation on which Scaldis has now successfully placed the topsides.

The hook-up work was performed by Multimetaal B.V., which included actually welding the topsides to the foundation. This is a specialist job for which the expertise of Multimetaal was called in. Multimetaal has the right knowledge and experience in offshore welding and the job was completed to the satisfaction of both Multimetaal and Hollandia.

The fully operational substations KFA, KFB and KFE are part of the Kriegers Flak Vattenfall’s 600 MW wind farm in the Danish part of the Baltic Sea.

Multimetaal has completed several hook-up projects in the past in both the oil and gas and offshore wind sectors.
