DEME Offshore installed the last of 94 wind turbines in the 752 MW Borssele 1&2 offshore wind farm. Owner Ørsted is planning to commission the wind farm on 5 October.

Borssele 1 & 2 comprises 94 wind turbines from Siemens Gamesa. Ørsted selected Siemens Gamesa’s SG 8.0-167 DD turbines with a tip height of 200 m, a rotor diameter of 167 m and 8 MW power. For Siemens Gamesa it is the first time to see this new turbine type to be installed in a commercial project.

The first turbine was installed in April 2020. DEME Offshore deployed the sister installation vessels Sea Installer and Sea Challenger for the installation. DEME was also responsible for the installation of the monopile foundations which took place between January this year and early June.

Henrik Egholm, EPC director Borssele 1 & 2 for Ørsted: “The construction of our wind farm went really well. Now we have completed the installation of the foundations, cables and turbines, in only 9 months. We have been able to construct the whole 752 MW wind farm, during a pandemic without anyone being infected which all can be very proud of. Naturally, we have worked according to the highest safety standard, both from a COVID-19 as from a construction perspective. I’m very proud of what we have achieved, together with our suppliers.”
