Over the past few years, inspectors in the pharmaceutical industry have been discovering major advantages by using indoor drones to gather visual data. These compact, specialized drones are designed to operate in tight and confined spaces, making them perfect for internal inspections of critical infrastructure.
Here are some of the key assets that inspectors use indoor drones to examine:
- Storage tanks
- Pipe racks
- Cables
- Conduits
- Pressure vessels
- Additional equipment requiring regular internal checks
Traditionally, these inspections required inspectors to enter the assets manually. They would move through the space with a flashlight and camera, capturing images to document the internal condition. For larger structures, they might need scaffolding or rope access, which adds time, cost, and risk.
All of these methods involve significant hazards—confined space entry, working at heights, and physical strain—posing serious risks to inspector safety. Indoor drones eliminate the need for direct human entry, allowing remote data collection from outside the asset. This not only improves safety but also cuts down on costs significantly.
One major pharmaceutical plant reported saving 60,000 Euros during a single inspection round by using an indoor drone. The drone collected visual data faster than a human, reducing downtime and getting the tanks back online more quickly. Such savings are common, with many companies reporting up to 90–95% reduction in inspection costs by switching to drones.
Drones also cut down on the time and expense associated with setting up and removing scaffolding. That alone can save hundreds of thousands of dollars per inspection. By eliminating the need for temporary structures, drones help reduce overall inspection time and improve efficiency.
Another major benefit is reduced downtime. Setting up scaffolding can take days or even weeks, during which the asset must be taken offline. Using a drone, the same inspection can be completed in a fraction of the time, cutting turnaround times dramatically.
Indoor drones like the Elios 2 provide high-quality 4K video and sharp images, along with stabilization and lighting features that help capture fine details. Inspectors recently used the Elios 2 to check the cleanliness of tanks during a riboflavin test. The drone captured clear visuals of the tank’s interior, allowing inspectors to assess conditions remotely without entering the tank.
These drones are built to navigate tight, complex environments. Their protective cages allow them to bump into surfaces and continue flying, giving inspectors easy access to hard-to-reach areas. This makes it possible to inspect walls, ceilings, and corners with ease.
Thanks to their speed and accessibility, drones enable more frequent inspections. Quick spot checks can be done regularly, helping to detect issues early and prevent unexpected failures. This leads to better maintenance planning and fewer unscheduled downtimes.
Finally, tools like Flyability’s Inspector 3.0 software help organize and track findings. Inspectors can mark defect locations directly in the footage, making it easier to revisit them later or share the data with other team members. This enhances collaboration and ensures nothing is missed during future inspections.
By integrating indoor drones into their workflow, pharmaceutical companies are not only improving safety but also achieving greater efficiency, cost savings, and data accuracy.
