Sulzer Schmid’s method of inspecting wind turbine blades has been awarded a US patent. RES, which acquired Sulzer Schmid last year, now has the ability to show customers both the internal and external image of blade damage in a single platform for the first time. 

 The 3DX inspection system uses drones, AI and robotics to provide a far more detailed assessment of blade damage. Blades are a critical part of turbines, with extremely complex structures and properties. Until now, critical maintenance decisions were using only half of the data – leading to increased maintenance costs and impactful downtime. 

The system helps wind farm operators identify issues early, reducing downtime and extending turbine lifespans. Wind turbine blades are among the most costly components to maintain, and this innovation aims to improve efficiency and cut long-term costs. 

Alex Bamberger, VP, Digital Services & Engineered Products at RES, said:
“As wind farms age, operators need reliable data combined with advanced digital tools to make informed maintenance decisions and extend the lifespan of turbines. This patented technology offers a more detailed and efficient way to assess turbine blade damage, ultimately reducing risks and lowering costs. This isn’t just about delivering better inspections—it’s about shaping the future of asset management and turbine efficiency.” 

Tom Sulzer, CEO of Sulzer Schmid concurred “We are incredibly proud of the role Sulzer Schmid played in developing this innovative blade inspection technology. Being part of the RES family now enables us to combine our expertise in turbine blade inspection with RES’ advanced digital solutions to deliver even greater value for the wind energy industry. This technology will transform the way operators manage turbine maintenance, ultimately improving performance, reducing costs, and enhancing the longevity of renewable energy assets worldwide.” 

The patent strengthens RES’ digital solutions business, which continues to push the boundaries of innovation in renewables through software and hardware solutions designed to optimise energy production and asset performance.
