We are trying to collect dilute erratic energy, spread over hundreds of square kilometers in windy, salty, and wet conditions with machines that spin at 330km/hour. What could possibly go wrong?
Ørsted must repair up to 2,000 wind turbine blades because the leading edge of the blades have become worn down after just a few years at sea.
The wind turbine owner will not disclose the bill, but says that the financial significance is “small”.
h/t “Offshore wind fiasco” at GWPF –The original story in Danish.
The cost of repair is so small they need to keep it a secret.
But it can’t be cheap. For the most part the blades need to be brought down, shipped and repaired on land. Repairing them at sea is a rare feat.
This must be the infamous leading edge erosion.
The Offwhore Wind Industry website discussed this type of damage in 2015:
Large rotors lead to large yields, but also to lots of annoyance – at least as far as the coating is concerned. After only a few years, the protective layer that is supposed to prevent erosion is already worn out. […]
