Upon successful completion of the GWO blade repair training course, the participant will be able to perform and document a wind turbine blade inspection, execute repair work in accordance with a work instruction while maintaining the aerodynamic profile and structural integrity in glass fibre reinforced composite parts of a wind turbine within the following dimensions:

  • Trailing edge repairs up to 1,5 m in length
  • Leading edge repairs up to 1,5 m in length
  • Laminate repairs down to core material
  • Core material replacement up to 200 cm²
  • Surface repair to paint and gelcoat
