Wind turbine inspection is an indispensable service to ensure the reliability, safety, and performance of wind farms. All wind turbine generator operations require regular maintenance and periodical inspections as over the years, all main components, from mechanical, civil, or electrical, suffer considerable wear that can affect the performance of the wind tower. To reduce this probability, periodical inspections of the main components are highly recommended.

As an experienced company in wind services, we can assist in the performance of any mandatory wind inspection or determining the real condition of a wind farm from different perspectives.


Applus+ engineers offer their clients turbine and blade inspection tailored solutions to ensure that the main components of their wind energy projects meet the highest quality standards.
