EEW Rostock places order with ILG for approx. 28,000 t of heavy plate for Sofia offshore wind farm
EEW Special Pipe Constructions GmbH selected Ilsenburger Grobblech GmbH as one of the suppliers for the construction of Sofia Offshore Wind Farm. Some 28.000t of heavy plates will be supplied in 2023 for one of the largest single offshore wind projects in the world.
At 1.4 gigawatts (GW) Sofia Offshore Wind Farm is one of the largest single offshore wind farms in the world. It will comprise 100 14 megawatt (MW) turbines that will be sited on Dogger Bank in the central North Sea, approximately 195 kilometres from the UK’s north east coast. Now under construction the project is 100% owned by RWE.
Sofia will use steel monopile foundations without a transition piece. The foundations will be between 80 and 90 metres in length and weigh between 1200 to 1400 tonnes each. Their diameters will be between 7.5 to 8.8m at the mudline. They will be installed by Van Oord's jack-up vessel Aeolus.
EPCI contractor Van Oord selected EEW Special Pipe Constructions GmbH to manufacture the monopile foundations. Ilsenburger Grobblech will supply in 2023 around 28.000t of heavy plates to EEW SPC in Rostock where the plates are rolled and welded to monopiles. The plates will be sent to Rostock in monthly volumes to meet the stringed production plan of EEW SPC.
This is another significant project for the Salzgitter Group to support the transition to green energy.
For the turbines, Sofia will use Siemens Gamesa Renewable Energy's SG 14-222 DD - a 14MW platform featuring 108 metre carbon and fibreglass blades cast in a single mould and a 222 metre-diameter rotor sweeping an area of 39,000m2. Each turbine will stand at 252 metres.
