Belgian construction company DEME is currently installing foundations for Vattenfall’s Vesterhav Nord and Syd offshore wind farms on the Danish North Sea coast. Installation of the 41 foundations, to support the 8.4 MW Siemens Gamesa offshore wind turbines, is handled from a new offshore wind port, the Port of Thyboron.
The foundations DEME is installing are the large steel structures of 41 monopiles and transition pieces (TPs). The 77m long monopiles, each weighing around 622 tonnes, are produced by EEW in Rostock, Germany. The associated TPs between the monopiles and the turbines are produced in Aalborg by Bladt Industries A/S. Each TP is 22.5m high and weighs 275 tonnes. DEME’s large installation vessel, Innovation, which is 147.5m long and 42m wide, is regularly sailing into the Port of Thyboron to load foundations, and then out to the offshore wind farms in the North Sea to install them.
