In December 2015 the ENGIE Fabricom, Smulders and CG consortium won the contract to design, supply and install the offshore substation for EnBW Energie Baden-Württemberg (EnBW). The substation has now begun sailing towards its destination, approximately 98km off the German coast and 90km north of Borkum island in the North Sea.

With its 55m length and 30m height, its 4,500 tonnes, 3 transformers and 3 shunt reactors, Hohe See is the biggest substation ever built at the ENGIE Fabricom Hoboken yard.

The substation will be installed on the jacket foundations, built by Smulders on their site in Vlissingen in the Netherlands which was transported to its final location in the German North Sea on the 29th May. CG is in charge of the high/medium voltage equipment.

For the construction of the substation, ENGIE Fabricom was responsible for the engineering, procurement, construction and commissioning of the offshore substation’s topside and the low-voltage installations and the offshore transport and offshore installation using the Thialf lifting vessel.

Smulders was in charge of the steel construction of the topside and jackets. CG was responsible for the design, manufacturing, installation and commissioning of the high/medium-voltage equipment, and control and protection systems for the platform.

The substation will be shipped directly from Hoboken to its final destination. The journey with the Thialf lifting vessel will take approximately three days, depending on the weather conditions. The installation aims to be done in the coming week.

The Hohe See wind farm is situated in the North Sea, 98km off the German coast. It consists of 71 turbines with 7MW capacity each. It is expected to generate approximately two billion kilowatt-hours of renewable electricity per year, which will be sufficient to supply 560,000 households and will prevent the emission of 1.5 million tonnes of CO2 a year.
