Wind Turbine Blade & Main Shaft Inspection Applications
Wind Turbine Blade and Main Shaft Inspection Applications
- Wind Turbine Blade Root Inspection
- Wind Turbine Blade Spar Cap Inspection
- Main Shaft Inspection
Wind Turbine Blade Root Inspection
- Inspection target: detection of de-laminations/dis-bonds in turbine blade’s root section (Glass Fiber Reinforced Polymer, GFRP)
- Inspection technique developed based on using low frequency conventional and phased array probes & Real turbine blade root section cut out used as calibration piece
- Bolt holes and made calibration targets were detected; Backwall trace showed sound penetration up to 4” from the surface
- Integrated in Acuren Turbine Blade Inspection program
Deployment: Wind Turbine Blade Root Inspection
- Blade Root Sections inspected on site and areas with delamination were market on the blade
Wind Turbine Blade Spar Cap Inspection
- Inspection target: detection of de-laminations/disbands in turbine blade’s Spar section (Glass Fiber Reinforced Polymer, GFRP and Carbon Reinforced Polymer, CFRP) and adhesive bond
- Inspection technique developed based on using low frequency conventional and phased array probes & Real turbine Spar section cut out used as calibration piece
Deployment: Wind Turbine Blade Spar Cap Inspection
- Technique demonstrated detection of dis-bond in both spar cap region and adhesive layer
- Inspection technique Integrated in Acuren Turbine Blade Inspection program
Wind Turbine Main Shaft Inspection
- Technique detecting cracks in main shaft of wind turbines developed for client
- Several shafts tested, one identified as potentially cracked
- More sophisticated, high resolution technique proposed for verification and through wall sizing
- New technique tested on demo sample cracked all the way through, crack facets clearly imaged
- Broader deployment with high resolution technique to be performed in 2024
