20 inspections in a day: Renewable Field Services

Renewable Field Services used automation to overcome inspection inefficiencies and weather delays. With Dhalion, their inspections became faster, more reliable and less dependent on the weather, with a record of 20 high-quality inspections in one day in Scotland in July 2025.

About them

Renewable Field Services is a blade specialist contractor offering inspection, repair and maintenance to wind turbine operators across several regions. Its team delivers a full turnkey service with authorised and competent technicians, helping owners maximise output and minimise downtime.

The challenge

  • Weather dependency: low- or no-wind days were marked as weather delay days, shrinking the inspection window.
  • Operational interruptions: flight path errors and lidar glitches caused inefficiency and rework.
  • Scaling: delivering more inspections without losing quality was hard.

What they did

Dhalion inspects with no wind or in winds up to 12 m/s, from 0 to 35 °C, which extends the inspection season. Perceptual Robotics also built a custom API integration that sends inspection data straight into their internal system, windmanager.io.

    Inspections

    Record

    In July 2025 their pilot did 20 inspections in a day, a full wind farm.

The results

  • Low- and no-wind days turned into inspection days.
  • Significantly less downtime and higher seasonal productivity.
  • No manual data handling thanks to the API, so fewer errors and faster decisions.
  • Excellent image quality across all four seasons.

In their words

“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.” And: “Image quality has been excellent throughout the blade season (for us this has included spring, summer, autumn & winter).” Renewable Field Services.

Reliable autonomous technology, smart integration and close collaboration let Renewable Field Services deliver more inspections in less time, in a wider range of conditions, with consistently excellent results.
