External and Internal Inspection

Wind turbine blades are subjected to extreme weather, operational stress, and occasional impacts from debris or lightning. Damage can occur both externally (surface cracks, gel coat erosion) and internally (delamination, sparcap or web damage). Detecting these issues early is crucial to prevent blade failure, reduce downtime, and maintain energy output. A comprehensive external and internal inspection allows for proactive maintenance, ensuring blades remain safe and efficient.

Common Signs You Need it

  • Visible surface damage such as cracks, chips, or discoloration
  • Unexplained performance drops or irregular turbine output
  • Vibration, noise, or imbalance during operation
  • Post-storm or post-lightning events
  • Historical maintenance records indicating recurring structural issues

What the Service Consists Of

Our external and internal inspection service combines visual, non-destructive, and advanced imaging techniques to assess blade condition thoroughly.

What's Included

  • Detailed visual inspection of blade surfaces for cracks, chips, erosion, or paint deterioration
  • Internal inspection using ultrasound, thermography, and borescope analysis to detect delamination, sparcap separation, or web damage
  • Drone-assisted imaging with AI for large-scale or hard-to-access areas
  • Documentation of defects with severity assessment and repair recommendations
  • Integration with maintenance teams for scheduling targeted repairs
  • Post-repair verification to ensure structural integrity and aerodynamic performance

Benefits

  • Early detection of both surface and internal blade issues
  • Reduces risk of catastrophic blade failure
  • Optimizes turbine performance and energy output
  • Minimizes downtime with targeted repair planning

External and Internal Inspection

Frequently Asked Questions

External inspection focuses on visible damage like cracks, chips, gel coat erosion, or paint deterioration. Internal inspection uses non-destructive testing methods such as ultrasound and thermography to detect hidden delamination, sparcap, or web damage that could compromise blade integrity. Both are critical for a complete assessment.

Routine inspections are recommended every 6–12 months, with additional inspections after storms, lightning strikes, or unusual operational events. Regular monitoring ensures defects are caught early and prevents costly repairs.

Drones provide high-resolution imaging and AI-assisted surface analysis, but internal inspection often requires borescopes, ultrasound, or thermographic scanning to detect delamination or internal structural issues that drones alone cannot see. Combining both methods yields the most accurate results.

Internal damage may be indicated by unusual vibration, noise, reduced turbine output, or findings from ultrasonic or thermal scans. Hidden delamination, sparcap cracks, or web separation can progressively worsen if left unaddressed.

The duration depends on turbine size and accessibility. Single-blade inspections can take 2–4 hours, while full multi-turbine farm inspections may span several days. Efficient planning and drone assistance help minimize downtime.

Yes. Comprehensive inspection reports, defect mapping, and repair recommendations support OEM warranties and insurance claims, providing documentation for accountability and compliance.

Findings are analyzed to prioritize repairs, schedule preventive maintenance, and allocate resources efficiently. By knowing exact defect locations and severity, operators can target repairs rather than replacing entire blades.

Yes. Thermal imaging, ultrasonic scans, and AI-assisted analysis can identify stress points, moisture ingress, and early-stage delamination that may develop into serious damage, allowing proactive maintenance planning.
