The offshore high voltage substation topside for the Norther offshore wind farm has been lifted onto its monopile foundation at the project site.  Installation was carried out using Scaldis Salvage & Marine Contractors NV heavy lift crane vessel Gulliver.

The substation topside measures 32m length, 21m in height and weighs 1,300 tons. It was built at the ENGIE Fabricom's facility in Hoboken in consortium with Smulders and CG.

The OHVS is one of the key elements in the functioning of an offshore wind farm because it connects the individual wind turbines to the onshore grid. The power generated by the wind turbines (33kV) is transported to this substation where it is converted to a voltage of 220kV and then delivered to the shore through one cable. Onshore it will connect to the Belgian grid through Elia’s Stevin high-voltage station.

The €1.2bn
Norther wind farm is being constructed 23km from the Belgian port of Zeebruges and is expected to be operational in 2019. It is owned by Elicio, Eneco & Diamond Generating Europe and is currently poised to be the largest project off the Belgian coast. The annual output of the wind farm is forecasted at 1.4 billion kWh, enough to supply 400,000 households.
