Fire on Borssele 1&2


One of the turbines at the Borssele 1&2 offshore wind farm off the Dutch coast malfunctioned and subsequently caught fire last week. Project operator Ørsted has reported that no employees were present when the fire broke out and no one was injured.

The damaged turbine has been dismantled and Ørsted is examining which parts of the turbine can possibly be reused. The turbine manufacturer Siemens Gamesa is investigating the cause of the failure in close collaboration with Ørsted. The other 93 turbines of reportedly show no abnormalities and are operating with the exception of the damaged turbine and two other turbines directly connected to it. These two turbines have not suffered any damage and show no abnormalities. Ørsted stated it is working to get these two turbines back online as soon as possible.

The project was officially inaugurated last month (6 September 2021) and is currently the largest offshore wind farm in operation in the Netherlands.

Ørsted won rights to the
Borssele 1&2 site in July 2016, with an average bid strike price, excluding transmission costs, of EUR 72.70/MWh for the first 15 years of the project's operation. The project is jointly owned by Ørsted and Norges Bank Investment Management (NBIM). It  features Siemens Gamesa Renewable Energy SG 8.0-167 DD turbines which are expected to provide power to over 500,000 households annually.

Construction for the project's onshore substation and installation of its offshore grid connection began in 2018. The foundation installation started in January 2020 and was completed by June that year despite COVID-19. The 94 monopiles were fabricated by Sif and EEW SPC. The 94 transition pieces came from Bladt and EEW OSB. Installation was completed by DEME’s installation vessel

Installation of the turbines began in April 2020 and was completed using installation vessels
Sea Installer and Sea Challenger from DEME Offshore, were deployed to complete the installation. The wind farm generated first power that same month. This was followed by full commissioning of all the turbines in November 2020.
