Our Drone Solution
Why waste days of extra down time to prepare and execute traditional inspection methods? Our drone can inspect these steel enclosed structures in a matter of minutes, rather than days. Whether it is verifying a few specific areas of repair from previous outages or visually checking the entire boiler for flat spots on the tubes, the Legacy One should be the first tool chosen when beginning an outage. Let our drone be the first object to make entry inside the boiler when it comes offline. It can be the robotic “birds-eye-view” to tell your company exactly what needs to be ordered during your outage.
Power Generation Uses
In April 2018, our team worked with a major U.S. power producer to prove scaffolding wasn’t needed for a routine boiler inspection. Our drone, combined with a UT thickness wall crawling robot, made a full coverage inspection of the boiler. The power company ultimately decided the combined robotic inspection was successful. This plant used to scaffold the entire boiler every other year, but is now reducing that requirement to every five years due to this test. Implementing this company wide will save them millions of dollars annually. This company also determined that the drone will be the first item to make entry to the boiler during the outage. It will make an initial visual assessment of the boiler before commencing with repairs.
coal bunkers & silos
Managing coal supply at a power plant can require a whole team to oversee. Legal requirements mean a company must have several days of emergency backup coal onsite. This typically results in coal storage using many different assets – whether they be inside the plant or outside. Following a recent coal bunker integrity disaster at a US power plant, multiple companies have implemented procedures to inspect inside these assets during plant shutdown. In 2018, Interactive Aerial flew the Legacy One inside a coal bunker by accessing the tank from the open top via temporary scaffolding. Pilots took off and flew below them to see the bottom funnel welds, along with the steel rafters that support the coal belts one floor above. Scaffolding these tanks are near impossible but using drones like the Legacy One makes it a simple and quick accomplishment.
If your company has hyperboloid cooling tower on your asset list, there’s a decent chance it does not get routinely inspected. By looking at the sheer size, it’s easy to understand why cost outweighs the value of checking these structures closely. The advancements of drone technology make 100% coverage of a cooling tower inside and out possible in just a few days’ time. Not only can your company gain a clear visual inspection of every inch, but sophisticated stitching software allows for a beautiful 3D model picture mosaic! In 2018, Interactive Aerial flew inside its first hyperboloid cooling tower, hundreds of feet in the air, over 4ft of standing water. The photo above was captured by the Legacy One 15ft away from the wall.
- Penstock – Penstock tubes at power plants create power through water flowing with gravity. These large tubes are often 20-30ft wide and could certainly be inspected with the Legacy One in lieu of climbing hundreds of feet up!
- Hydroelectric Dams – These large power production facilities are complex structures that may require flights to multiple different hard to reach areas. Consider the Legacy One to access those large vertical walls!
