Wind turbine blade inspection using drones: how does it work?

How can you keep your wind turbine blade inspection cost-effective?

One way is through using drones to help with standard visual inspections. These handy pieces of equipment can significantly cut down the time required for general visual inspections, as well as reduce the amount of time that technicians are on site. 

In this blog, we will unpack how drones can help you save money, ensuring you can safeguard the longevity and efficiency of these impressive structures.

Wind turbine blade inspection at NDT Renewables

As you know, over time, exposure to harsh weather conditions and constant motion can take a toll on blades. Cracks, erosion and other defects can compromise their performance, leading to decreased energy production and higher maintenance costs. 

To address these concerns effectively, frequent wind turbine blade inspections are essential. At NDT Renewables we work hard to ensure that our technicians are highly skilled and able to deliver accurate tests in a timely manner. We use drones to ensure that general wind turbine inspections are conducted as cost-effectively as possible. 

All of our technicians are certified Level 2 PCN or over and hold IRATA Rope Access certifications, which allow us to perform tests at height or in difficult-to-access areas.

All of the technicians who work for NDT Renewables are GWO-certified, ensuring that they are trained to reduce the risk associated with working in the wind turbine industry.

The evolution of blade inspection

Traditionally, blade inspection was a labour-intensive and risky process that involved climbers scaling the towering turbines to visually assess and document any damage. 

This method was also time-consuming and costly. 

However, with advancements in technology, the industry has embraced a safer and more efficient alternative: wind turbine blade inspection using drones.

Wind turbine blade inspection using drones involves the use of unmanned aerial vehicles equipped with specialised cameras and sensors. 

These drones are designed to navigate the challenging environment around wind turbines and capture high-resolution images and data. 

Here’s a step-by-step overview of our process:

1. Drone deployment 

Our specially trained technicians deploy the drones near the wind turbine. These drones are often equipped with rotor blades designed to withstand the strong winds and turbulence in the vicinity of the turbine.

2. Data collection 

Once in position, the drone begins its inspection mission. High-resolution cameras and sensors capture images and data from various angles and distances. These sensors can detect even the slightest imperfections on the blade’s surface.

3. Real-time analysis 

The data collected by the drone is transmitted in real-time to a ground station, where it is analysed by our experts. Advanced software processes the information, allowing our inspectors to identify any damage or defects.

4. Damage assessment 

After the analysis, our technicians can determine the severity of any damage found on the wind turbine blade. This information is crucial for planning and prioritising maintenance or repairs.

5. Comprehensive reports 

Detailed inspection reports are generated, providing a comprehensive overview of the blade’s condition. These reports include images, measurements, and recommendations for further action.

Advantages of using drones for blade inspection

The adoption of drones for wind turbine blade inspection offers numerous benefits:

1. Safety 

One of the most significant advantages is the increased safety of technicians. Using drones for general visual inspections reduces the need for risky climbs, reducing the potential for accidents and injuries.

2. Cost-efficiency 

Drone inspections are more cost-effective than traditional methods. They require less personnel, less equipment, and less downtime for the wind turbine.

3. Efficiency 

Drones can complete inspections quickly, reducing the overall time taken to conduct the test. This efficiency translates to higher energy production and lower maintenance costs.

Wind turbine inspection: safe, accurate, efficient with drones 

Wind turbine blade inspection using drones represents a significant leap forward in the maintenance and efficiency of wind energy generation. 

By enhancing safety, accuracy, and cost-efficiency, drones are helping ensure that these iconic structures continue to provide clean and sustainable energy for years to come. 

As technology continues to advance, we can expect even more innovative solutions to emerge, further solidifying wind energy’s place in our sustainable future.
