Innovative technology and specialized equipment allow us to complete inspections in hazardous areas at full power. Traditionally, a generation facility’s refueling outage is the only time a plant can be accessed to due the high temperatures, dose conditions, and need for scaffolding.
To complete the inspection in an inaccessible area at a generation facility, we deployed a specialized drone with infrared technology. The drone was specifically designed to fly in a GPS denied environment, so no personnel were put at risk.
We were asked to troubleshoot 55 inaccessible valves that, if the seat is leaking by, would result in efficiency losses in power generation.
The infrared technology allowed subject matter experts (SME) the ability to detect up and down steam heat flow to asses for valve leak by. This valuable media allowed the station to make decisions on which valves need future maintenance and identify any degraded components.
