Evaluation of Lagerwey L 82 wind turbines

The evaluation report contains all of the calculations for the successful certification of loads according to the IEC 61400-1, Edition 3. Lagerwey Wind is the second of GL’s customers fulfilling this standard.

Currently GL Renewables Certification is performing the design evaluation, which is the IEC equivalent to the GL Design Assessment. In the case of L 82, the assessment is based on IEC WT 01.

The Lagerwey wind turbine L 82 was erected and commissioned in Grevenbroich, Germany in December 2009. It has been operating without detraction since it started to produce wind energy in February.

IEC 61400-1 specifies essential design requirements to ensure the engineering integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime.

This standard is concerned with all subsystems of wind turbines such as control and protection mechanisms, internal electrical systems, mechanical systems and support structures, and applies to wind turbines of all sizes.

Lagerwey Wind concentrates on the development of innovative wind turbine concepts with a focus on direct drive. The goal is to provide the market with designs that can be adapted to the special needs of the customers, by delivering bespoke designs from scratch. The expertise in design spans the range from very small to megawatt wind turbines.
