Rotor blade inspections inside and outside

Identify early — take targeted action. For secure returns and long operating times.

Rotor blades are among the most critical components of any wind turbine. They are permanently exposed to extreme weather and environmental influences — from UV radiation to rain, ice, wind loads and lightning. Damage often remains undetected for a long time, but quickly leads to loss of income, high repair costs and downtime.

With over 20 years of experience and cutting-edge testing technology, 8.2 offers independent rotor blade inspections — from manufacturing process to recurring testing, onshore and offshore.

Rotor blade external inspections

Condition assessment & early fault detection

• Visual inspection, documentation and evaluation of external damage
• Inspection of lightning protection and grounding systems

Rope access technology for maximum flexibility

• Access to all blade areas without crane or lift
• Minimal downtime, no restrictions due to terrain or hub height
• For all common plant types
• Can be combined with lightning protection continuity measurement

Drone inspection for a quick overview

• Visual inspection of surfaces and mounted components

Rotor blade internal tests

By an internal rotor blade test, the condition of essential structural elements and installation parts of rotor blades can be determined.

Inspection of load-bearing structures and components

• ‍‍Inspection of adhesions, laminates, belts and built-in components (e.g. lightning protection, sensors, heating systems)
• Inspection of the factory, after transport or installation

Inspection of inaccessible areas with Rover

• ‍‍Remote-controlled camera vehicle for inspection down to the tip of the blade
• Live control by 8.2 experts, analysis of recordings on site

Video endoscopy when needed

• Detailed inspection in particularly hard-to-reach areas

Why 8.2 for your blade inspection?
