The GWO Blade Repair Training Course is a comprehensive 9-day program designed for wind industry professionals who want to gain the skills and certification required to safely inspect, maintain, and repair wind turbine blades in accordance with Global Wind Organisation (GWO) standards. The course combines in-depth theory with extensive hands-on practical training to ensure participants develop the confidence and competence needed to work on real turbines.
Wind turbine blades are critical components of modern wind energy systems. Any damage, whether from environmental conditions, wear, or operational stress, can significantly affect turbine performance. The GWO Blade Repair Trainingequips participants with the knowledge and practical expertise to identify, assess, and repair damage while maintaining the aerodynamic profile and structural integrity of blades made from glass fibre–reinforced composite materials.
The GWO Blade Repair course duration is 9 days, covering both classroom sessions and practical workshops. Participants will gain experience performing inspections, planning repairs, and executing work according to GWO-approved work instructions. This hands-on approach ensures technicians are ready to perform repairs safely and efficiently under real-world conditions.
During the course, participants will gain the skills to:
Conduct thorough wind turbine blade inspections and document findings
Execute laminate repairs, including leading-edge and trailing-edge repairs
Replace core materials and perform surface repairs to paint and gelcoat
Maintain structural integrity and aerodynamic performance after repairs
Work safely at height and in compliance with GWO safety standards
Follow safe handling procedures for composite materials
The course includes practical training within the following limits:
Laminate repairs: Up to five layers, maximum repair area 500 cm²
Core material replacement: Maximum repair area 200 cm²
Surface repairs: Paint and gelcoat restoration
This course is ideal for:
Wind turbine technicians seeking professional advancement
Blade repair technicians looking to gain certification
Maintenance personnel in the wind energy sector
Professionals aiming to meet GWO certification requirements
Upon successful completion, participants receive a GWO Blade Repair Training Certificate, which is:
