Rotor blade inspection inside and outside
Robustness starts with knowledge — precise condition assessment under offshore conditions
Rotor blades of offshore wind turbines are constantly exposed to extreme loads: salty air, strong winds, driving rain and UV radiation put the material under stress over many years. Damage often occurs gradually — and often remains undetected for a long time in harsh offshore environments.
8.2 has been carrying out qualified rotor blade inspections for over two decades — independently, manufacturer-neutral and with special expertise in the offshore sector. Our tests cover both the outer and inner structures of the rotor blades — from the initial operating phase to periodic testing.
Exterior inspections: Identifying damage — ensuring operational readiness
Visual inspection and system control
- Recording of external damage by means of visual inspection and structured documentation
- Verification of lightning protection and grounding system
Access via rope technology or drone
- Flexible access to all blade areas without additional infrastructure
- Implementation even with restricted weather windows and limited offshore time
- Combination with lightning protection continuity measurement possible
- Drone footage for a quick overview of surface conditions and attachments
Interior inspections: A deeper look at the rotor blade
Focus on supporting structures and built-in components
- Inspection of adhesive bonds, laminates, belts and components such as lightning protection, sensors and heating systems
- Inspection in the factory, on the platform or after installation
Technology for hard-to-reach areas
- Remote-controlled camera rover for access to the tip of the blades
- Video analysis in real time by experienced rotor blade inspectors
- Optional: Endoscopic inspections where accessibility is restricted
Why 8.2 in offshore blade inspections? Offshore expertise that works
- Specialized experience from major offshore projects with different turbine types
- Working safely under offshore conditions — including trained height workers
- State-of-the-art testing technology and standardized reports for operators, OEMs and insurers
- Documentation for submission to authorities or as part of warranty claims
With rotor blade inspections of 8.2, you ensure the long-term operation of your offshore plant — early, reliable and independently assessed.
