Additive Manufacturing in Blade Production

The rise of additive manufacturing could translate into optimizing individual tower blades for their wind and turbulence patterns at each location on a wind farm.

Additive manufacturing (AM) has been around for a little over 30 years. It brought agile development into the manufacturing world because companies could now rapidly prototype. There have been substantial scalability issues leading to no significant changes in traditional industrial manufacturing practices. However, this is rapidly changing. The introduction of new technologies, better simulation, and […]

Extending the Lifetime of Wind Turbines

The results of lifetime extension assessments conducted by TÜV SÜD indicate that most turbines can continue to operate in a safe and economically viable way for several years beyond their defined service lives.

Wind turbines have a planned service life of approximately 20 years. Nevertheless, it has been demonstrated that many turbines are able to operate beyond their design lives. In several instances, the lifetime of a wind farm may be extended through minor and low-cost repairs. In order to establish whether a wind turbine can continue to […]
