EU inspection innovation

PES brings you WInspector, an advanced and innovative approach for on-site inspection of wind turbine blades. A research and innovation project which is part of the European Union’s Horizon 2020 programme.

A consortium, composed of five members, TWI, WRS, Innora, Gamesa and London South Bank University has come together to find a solution for wind turbine blades inspections, by means of the development of a laser shearography system placed on a robotic platform, under the project WInspector.


Nowadays, Wind Turbines (WT) are one of the most efficient ways to produce green and sustainable energy, contributing in a high percentage to all renewable electricity. However, due to the stress suffered by the blades and caused by wind gusts, there is a continuous need for inspection and maintenance.

According to CWIF an average of 3,800 blade failure incidents annually are attributed to poor maintenance, with a cost varying between 90,000€ and 900,000€ each, involving many accidents resulting human injury and fatalities. Blades reparations can be costly in downtime and expensive, and at the same time this fact reduces turbine’s operational efficiency. For these reasons, preventive planning through more frequent inspections is a necessity.
