Expertise – NEW!


Wind turbine blades must be inspected every six months since the publication of the new ICPE decree.

OpenR is able to perform these blade inspections on a wide range of wind turbines using the Cornis Panoblade tool. This solution and the dedicated online platform allow a complete inspection of the blades in less than one hour per machine and a precise analysis with Cornis Artificial Intelligence.

Do not hesitate to contact us for more information on our offers! We’ll be able to pool these blade inspections with other regulatory controls! Contact us:
