4 FAQs about Paused wind turbine blades

What happens to wind turbine blades during service?

Wind turbine blades are subject to complex environmental and mechanical loading during their service time, including cyclic deformation, rain, sand and contaminants causing erosion, icing, high moisture and temperature variations, but also extraordinary events, such as transportation damage, lightning strikes and bird impacts [9, 10, 11, 12].

How are wind turbine blade failure mechanisms analyzed?

Generally, failure mechanisms of wind turbine blades are analyzed using the following main methods: Computational modelling of blade deformation and damage. Post-mortem analysis of failed or damaged blades (either test blades or blades taken from old or damaged wind turbines) is the most obvious approach to explore the blade failure mechanisms.

Can a wind turbine blade be pulled from its hub?

As a result of root end failure, the blade can be pulled from its hub during the service time. Lee et al. reported that blade failures observed in the field at Eclipse and Ocotillo wind farm in 2013 were caused by pulling out the blades from the wind turbines due to delamination at the root.

When will a European ban on dumping wind turbine blades take effect?

From January 1, 2026, a self-imposed European ban on dumping wind turbine blades will take effect. WindEurope is consolidating circular solutions and urging EU policy action. - NedZero From January 1, 2026, a self-imposed European ban on dumping wind turbine blades will take effect.
