“Just imagine extreme weather conditions or hailstorm hitting the blades at more than 300 km/hour. Effective inspections and repair require a proper understanding of the blade design. Blades will perform and last a lifetime if they are thoroughly maintained.” - Frank Virenfeldt Nielsen, Chief Technology Officer, LM Wind Power Group
Wind turbine blades are exposed to heat, sand, rain, snow and hail and often the extreme weather conditions erode the surface. Wear and tear negatively affects aerodynamics, and increases turbulence in the blades resulting in reduced overall turbine input.
Periodic service and maintenance sustains and even improves performance over the blade’s lifetime. Further, regular inspections and maintenance of blades help prevent minor defects from developing into structural cracks. And early analysis and repair of visible cracks is crucial in avoiding larger repairs in the future.
