Blade surface condition reported turbine by turbine — leading-edge erosion, cracks, delamination and lightning strike damage, each located by blade, side and distance from root, with nacelle and tower condition from the same flight.
THERMAL + RGBEvery finding in every report follows the same structure — location, frame reference, affected area, confidence, probable cause and recommended action, rated Red / Amber / Green. Here's a worked (illustrative) example from this survey type.
| Location | Turbine 04, blade B, leading edge, 12–18 m from root |
| Frame reference | 0114_V – 0121_V |
| Estimated affected area | Approx. 6 m of span |
| Confidence | High |
| Severity rating (RAG) | AMBER |
Observation: Coating loss and substrate exposure along a continuous section of the leading edge, with the affected band widening toward the tip. The adjacent blades show early-stage wear only.
Probable cause: Consistent with rain and particulate erosion at the high-velocity section of the span — the expected wear pattern for this position and turbine age.
Recommended action: Recommend leading-edge protection repair at the next scheduled maintenance window. Erosion at this grade increases drag and reduces annual energy production if left.
Every finding on every survey type is rated against the same published definitions, so a Red on one job means the same thing as a Red on the next.
