CG installs its largest ever offshore transmission substation in Germany
Avantha Group Company, CG Power and Industrial Solutions Limited (CG) through its wholly-owned subsidiary at Belgium in consortium, fabricated the largest ever Offshore Transmission Substation with overall electrical transmission design, manufacturing, installation to commissioning and energization of all main Power Transformers, High & Medium Voltage Equipment and Control and Protection Systems for the Electrical Transmission Platform.
In 2015, CG along with ENGIE Fabricom and Smulders contracted to design, supply and install the offshore substation for the German utility EnBW (Energie Baden-Württemberg).
The structure is 55 metres long, 30 metres high and weighs 4500 tonnes with 3 Main Transformers and 3 Shunt Reactors. Hohe See is the largest substation built so far at the Hoboken yard. The Hohe See Wind Farm is the biggest planned offshore wind project in Germany with 71 turbines- a total capacity of 497 MW. It is expected to generate approximately 2 billion kilowatt-hours of renewable electricity per year, adequate to power 560,000 households and reduce CO₂ emissions by over 1.5 million tons per year.
On 29th May 2018, the jacket for the EnBW Hohe See Offshore Wind Farm left the Smulders yards in Vlissingen. The jacket will be installed in the German North Sea. The substation is shipped directly from Hoboken to its final destination. The journey with the Thialf lifting vessel, the largest installation vessel, took 3 days for a successful installation on the offshore foundation.
