Proper blade maintenance for optimal turbine performance

Blades have been the so-called ‘underdog’ in wind energy for a long time. Its use was practical but not seen by definition as a vital element. Only later did the industry became aware of its importance in the energy production of a wind turbine. Dutch blade inspection and repair specialist Redak has witnessed this process…

Safe upscaling of wind turbines

Boltlife’s blade to hub flange connection methodology Wind turbine generators get bigger and bigger each year. As a result, the dynamic forces on a rotor blade during its operation become immense. These tremendous forces are transferred through the blade-to-hub connection, which makes it imperative that this connection doesn’t have any weak points. This poses challenges…
