Our blade inspectors are not only specially trained rope access personnel but also qualified rotor blade experts. They work hand in hand with our engineering department to deliver the following services:

Onshore and Offshore Rotor Blade Inspections


Industry experience has proven that after two years of operation the possibility of damages on rotor blades increases as the blades begin to wear from exposure to elements & other influences. After five years of operation annual inspections are strongly recommended. Exposed glass fibre is not resistant to ultraviolet rays and will begin to absorb water. We work according to Principles for Monitoring the Condition Based Maintenance of Wind Turbines to ensure the delivery of inspection reports to the highest standards.
