Hohe See substation leaves the ENGIE Fabricom yard in Hoboken
The ENGIE Fabricom, Smulders and CG consortium has won in December 2015 the contract to design, supply and install the offshore substation for EnBW (Energie Baden-Württemberg). Yesterday evening the substation began sailing towards its destination, approximately 98km off the German coast and 90km north of Borkum island in the North Sea.
With its 55 metres length and 30 metres height, its 4,500 tonnes, 3 transfomers and 3 shunt reactors, Hohe See is the biggest substation ever built on 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 29 May. CG is in charge of the high/medium voltage equipment.
The Hohe See wind farm is situated in the North Sea, 98 km off the German coast. It consists of 71 turbines with 7 MW capacity each. It is expected to generate approximately 2 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 per year.
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 (capacity 14,200 T). 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, the largest installation vessel, will take approximately three days, depending on the wheather conditions. The installation will be done in the coming week.
Smulders is an international steel construction company with a proven track record in the engineering, production, delivery and assembly of heavy, technically complex steel constructions. With over 50 years of experience in its field, Smulders was the logical choice for offshore wind structures back in the pioneering days of wind energy more than 15 years ago. Today, Smulders is an established market leader and can boast delivery of 20 substations and their accompanying foundations and more than 1,500 transition pieces and 100 jackets.
CG is an established turnkey ‘design & build’ contractor for onshore and offshore grid connection infrastructure. CG also manufactures SLIM wind turbine transformers, power transformers, switchgear, automation and control products in addition to being a market leading providor of transformer related services.
