Renewable Field Services (Renewable FS) is a blade specialist contractor providing inspection, repair, and maintenance services for wind turbine operators across multiple regions. Their team is able to offer a full turnkey solution, including their own Authorised / Competent Technicians provision and their role is critical in helping asset owners maximise energy output and minimise downtime.

Traditional inspection methods often meant delays. Low- or no-wind days were lost as “weather delay days,” while flight path errors and lidar glitches caused interruptions and inefficiencies. To scale their services and deliver more reliable results, Renewable FS needed a smarter solution.

How Dhalion Changed the Game

Perceptual Robotics’ Dhalion autonomous drone system provided the answer. With Dhalion, Renewable FS saw reliable flights with significantly fewer interruptions, coupled with consistently high-quality images across all seasons. Inspections became faster and more cost-effective, supported by a customisable portal that gave their blade specialists full control over capture, annotation, and reporting. 

To take productivity a step further, Perceptual Robotics also developed an API integration, allowing Renewable FS to seamlessly transfer inspection data into their internal systems. This eliminated manual handling, reduced errors, and ensured inspection results could be turned into decisions more quickly. Throughout, the partnership was reinforced by responsive collaboration, with the Perceptual Robotics Support Team rated as “Excellent”.

Impact Beyond Productivity

The results have been immediate and measurable. Renewable FS carried out more than 400 inspections in 2024. Using the Dot drone, their team even set a record of 20 inspections in a single day, showing both the efficiency of the process and the robustness of the technology. Perhaps most importantly, low-wind days are no longer considered downtime. 

As Renewable FS explained, “The ability to now inspect on low/no wind days due to not requiring the rotor to be positioned has significantly reduced our down time. This has therefore increased our seasonal productivity.”

The improved reliability has also delivered consistently excellent results.

As the team noted, “Image quality has been excellent throughout the blade season (for us this has included spring, summer, autumn & winter).”

By combining reliable technology, seamless integration, and strong collaboration, Renewable FS has transformed the way they deliver blade inspections, achieving more inspections in less time and creating lasting value for their customers.

At Perceptual Robotics, we’re proud to support their mission with Dhalion’s cutting-edge capabilities and excited to continue building on this collaboration in the seasons ahead.
