Inspection of rotor blades

Regular inspections of rotor blades are an important part of maintenance based on the site conditions. They are required by most insurance companies. Through regular inspections it is easy to spot existing damages. This is an important requirement in order to repair damages early and with low expenses.

We have extensive engineering know-how in the repair of fiber-reinforced plastic components. Furthermore we developed a special work technique based on the use of ropes. Therefore no cranes are requireed and costs for accessing the blades are reduced. In addition this method has the advantage of allowing us to reach all areas of the blade, regardless of the hub height. And also the control of the blade interior is usually included in the inspections.

According to your requests we carry out different inspection tasks:

  • Damage control of blade exterior
  • Condition and position control of existing flow elements
  • Inspection of the blade interior
  • Inspection of the lightning protection system of the rotor blades
  • Inspection of the tip-mechanism at stall-controlled wind turbines
  • Execution of special inspection tasks with versatile measuring and control equipment:
      » Internal check of the blade tip by means of a special camera system
      » Endoscopy of damaged areas in the interior of the blade
      » Analysis especially of low frequency vibrations by means of a special vibration easurement system
      » Layer thickness measurement, material check-up, ultrasonic check
