Description of the course
Target group
Personnel who will be working in the wind industry specifically in relation to composite inspection and repair work. Personnel that perform job functions that have been risk assessed by their employer or their workplace duty holder as a function, where composite work training according to this standard may mitigate some of the identified hazards and risks.
Objectives of the course
The aim of the GWO Blade Repair training module is to enable the participants to support and care for themselves and others working in the wind industry by possessing the necessary knowledge, skills and ability for blade repair.
After having successfully completed the GWO Blade Repair training the participants will be able to:
  • Take responsibility for working safely with applicable chemicals, while utilising the applicable personal protective equipment in a controlled manner throughout all phases of blade inspection and repair work (Ability, intermediate level);
  • Explain typical types of blade construction, materials and the importance of surface finish relating to aerodynamic performance and efficiency (Knowledge, intermediate level);
  • Distinguish between and work safely in a controlled manner with epoxy, polyester, polyurethane, vinyl ester, methacrylate, reinforcement materials and solvents related to composite inspection and repair work (Skills, intermediate level);
  • Prepare, operate and maintain the correct tools and equipment, be it electrical or mechanical (Skills, intermediate level);
