On both sides of the Atlantic ocean recently a total of four wind turbines fell down and one more dropped a 40-meter long blade. In Nova Scotia, a 15-year old Vestas 660 kW turbine collapsed in Grand Etang as a result of strong winds. In Germany, a 100-meter tall turbine collapsed in Hamburg in early January; a 95-meter tall turbine collapsed in Saxony in late December; and a 70-meter tall turbine fell in Suderholz in early December. The turbine that dropped its blade was in Zichow, which is in the northern part of the country.
One of the fallen German turbines was 16 years old and one was 18 years old. Each incident is being investigated thoroughly according to the stories below.
Perhaps drone technology could help in the future. See our recent piece on advances in wind power O&M through drones. Offshore Wind O&M Will Soon Be Aided by Drones and Drones to Play Greater Role in Wind Turbine Inspections
