Inspection drones, also known as unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UAS) are becoming widely used for industrial applications as a safer, faster and more economical way to conduct often complex inspections.

In the pulp and paper industry, traditional inspection methods come with many challenges including reduced production rates and costs such as labor, scaffolding, and equipment. Other challenges include the complexity and size of boilers, with intricate systems and components as well as safety and access concerns.

Many of these challenges are being overcome by embracing more advanced inspection methods such as drone technology which offers several benefits over traditional inspection methods, including:

1. Safety

Inspection drones are remotely operated negating the need for workers to access hazardous or hard-to-reach areas. Scaffolding scope is greatly reduced or removed entirely, and a confined space inspection becomes easier to complete with drones that can be safely navigated around the boiler or other industrial assets. Safety is significantly improved by minimizing the risk of injuries and accidents.

2. Cost-effective Early Detection

Most industrial drones have a maximum operating temperature of 42^oC, enabling drone inspections to be conducted whilst the boiler or digester is cooling down. This allows inspection data to be analysed earlier during a turnaround and any issues identified and resolved, preventing costly downtime.

3. Improved Data Collection

The drone creates an accurate 3D map of the environment and remote HD live streaming of images and videos aids collaborative decision-making between maintenance managers, regardless of where they are in the world.

3-D mapping creates an accurate data set to conduct additional reviews and root cause analysis after the outage is complete, to minimize the risk of future damage or boiler failure.

4. Reduced Downtime

Regular drone inspections ensure that potential issues are identified early, allowing timely maintenance or repairs to take place. Any areas of interest can be logged and documented for monitoring purposes. This reduces unexpected downtime and production interruptions.

5. Rapid Inspections

Inspection drones can cover large areas and structures in a relatively short amount of time; it usually takes one shift to complete a drone inspection. This provides rapid assessments and reduces operational disruptions. Furthermore, high-powered illumination and integrated sensors allow the drone to safely operate in any light conditions.

Conclusion

Overall, inspection drones provide a valuable tool for improving the efficiency, safety, and effectiveness of industrial inspections, making them an increasingly popular choice for sites looking to enhance their inspection and maintenance processes.
