Visual Survey & Structural Assessment
Two IRATA Level 3 technicians descend the full blade span — root to tip — on independent rope systems. Every surface crack, leading-edge erosion pocket, and lightning receptor condition is documented with geo-tagged photography. We run the tower exterior simultaneously: flange bolts, cable ladder anchor points, yaw ring seal condition.
Most operators skip the full-length rope inspection because it costs more than a platform visit. It also catches the fatigue crack at 58 metres that the platform missed for three seasons.
What You Receive
Internal Blade & Nacelle Cavity Inspection
A 6-metre articulating borescope enters through the blade root access port. We document every internal web adhesive bond, spar cap condition, and moisture ingress indicator. Inside the nacelle: main shaft bearing race, gearbox housing seals, generator coupling alignment — all captured in 4K with thermal overlay where heat signatures require annotation.
Thermal overlay catches a gearbox bearing running 12°C hot before it shows up in SCADA vibration data. That is a scheduled swap versus an emergency crane mobilisation.
What You Receive
Particle Count, Viscosity & Contaminant Profiling
Oil samples are drawn from the low-speed and high-speed stages separately — not from the drain port where settled particles skew the count. Samples go to our ISO 17025-accredited lab partner same-day via courier. Results include ferrous particle count, water activity, viscosity index, and a remaining useful life projection keyed to your OEM's wear band thresholds.
We have pulled oil samples showing 4× the ISO cleanliness limit from turbines that passed their last visual inspection. The gearbox failed eleven weeks later. The operator who acted on our data avoided the failure entirely.
What You Receive
Leading-Edge Erosion Restoration
Erosion repair is performed in-situ on rope — no crane, no blade removal. We grind back to clean laminate, apply 3M Wind Blade Protection tape or OEM-specified polyurethane coating in temperature-controlled conditions, and cure under portable heat blankets. Each repair section is thickness-checked with an ultrasonic gauge before the technician ascends.
A 1% improvement in blade aerodynamic efficiency on a 2 MW turbine running at 35% capacity factor adds roughly $11,000 in annual revenue at $0.045/kWh. Our in-situ repair costs a fraction of crane mobilisation.
What You Receive
Final Commissioning Report & Handover
Every service call closes with a structured commissioning report: all findings catalogued by severity (IEC 61400 classification), all repairs documented with materials batch numbers, all measurements recorded against OEM tolerance tables. The report is formatted for direct upload to your CMMS — we support SAP PM, Maximo, and Infor EAM schemas on request.
Asset managers tracking availability percentages need data that feeds directly into their reporting stack. We have built the output format around your system, not ours.

Nacelle found a spar cap adhesive disbond on Unit 47 that our platform inspection missed two seasons running. The borescope report was in our CMMS within 72 hours. We deferred crane mobilisation by eight months.
When our commissioning timeline compressed by three weeks, Nacelle had a six-person crew on-site in 96 hours. GWO documentation was pre-loaded in our contractor management system. Zero HSE events across 18 turbines.
Their oil analysis caught a water activity spike in the gearbox hydraulic circuit at Unit 12. We pulled the seal kit on a planned outage day. That saved us roughly $340,000 in unplanned downtime costs.
