Sutro Group delivers rapid internal blade inspection capabilities using Elios 3 drone technology. This solution cuts inspection time by 80% while eliminating confined space entry requirements. The system provides comprehensive internal blade assessment with superior data acquisition through 4K imaging and LiDAR mapping – all without exposing personnel to height and confined space risks.
Why choose drone inspections for wind turbines?
Wind turbines are essential to the global renewable energy transition, but their maintenance poses significant challenges. Traditional inspections require specialised training, working at extreme heights, and navigating confined spaces. The Elios 3 eliminates these challenges, offering a safer, faster, and more cost-effective solution.
The challenge:
A wind turbine management company sought a faster, safer, and more efficient way to inspect the internal structures of wind turbine blades. Traditional methods required workers with confined space training to manually enter each blade, a process taking up to 2 days per turbine.
The solution:
Using the Elios 3, a full internal blade inspection in just 27 minutes per blade, compared to the 4+ hours required with rovers or 2 days with manual entry. The drone’s 4K camera captured critical data on lightning strike damage and maintenance issues, while the real-time LiDAR point cloud provided precise navigation inside the confined space.
The results:
- Inspection time reduced from 5 days to 1 day.
- No human entry is required, reducing risk and specialised labour costs.
- More detailed and actionable data was collected, enabling predictive maintenance.
- Improved operational efficiency, minimising turbine downtime.
How it works
- Drone Deployment: The Elios 3 is launched from the hub, navigating each blade with ease.
- Real-Time Data Capture: 4K imaging and LiDAR mapping identify defects and areas of concern.
- Rapid Data Processing: Inspection reports are generated within hours, delivering immediate insights.
- Actionable Maintenance Plans: Detailed reports help optimise repair schedules and reduce turbine failures.
