Wind turbines are expected to last between 20 and 25 years, with proper maintenance to keep them in consistent working order. Current inspection techniques including drone-based approaches are limited to surface defects only. The EU-funded Romain project will develop a robotic inspection and repair solution of wind turbine blades, both onshore and offshore. By integrating thermography and shearography with laser heating, it will be possible to carry out in situ inspection of both surface and subsurface defects. The project will also develop a robotic deployment system to hold the inspection unit and a robotic repair arm operated by engineers working on ground or on a vessel (for offshore wind farms). The repair arm will be able to repair the defects detected.
