DEME has chosen Denmark’s Port of Thyboron as a base for the installation of foundations for Vattenfall’s Vesterhav Nord and Syd offshore wind farms.
The 41 foundations will support 8.4MW Siemens Gamesa offshore wind turbines.
The 77 metre-long monopiles, each weighing around 622 tonnes, will be produced by EEW in Rostock, Germany.
The associated transition pieces (TPs) between the monopiles and turbines will be produced in Aalborg by Bladt Industries.
Each TP will be 22.5 m high and weigh 275 tonnes.
The large foundations will be shipped in sets to the Port of Thyboron on barges during spring.
DEME’s large installation vessel, Innovation will regularly sail into the Port of Thyboron to load foundations, and then out to the offshore wind farms in the North Sea to install them.
DEME’s project manager, Jan Van de Velde said: “There are clear advantages in the fact that we can work undisturbed at the quay in Thyboron throughout the installation project, and without troubling others as we work at the port.”
