Terra Drone Corporation has successfully demonstrated its non-destructive testing (NDT) capabilities by inspecting a 160-meter chimney at a thermal power plant in Japan.
The chimney inspection was conducted using ultrasonic testing (UT) drone developed by Terra Drone group company Terra Inspectioneering.
A major component of the chimney inspection was to measure the thickness of the steel plate in a chimney windshield or flue. Conventionally, this would have been done manually by shutting down the facilities, putting up temporary scaffolding, and having human inspectors climb dizzying heights – in this case, 160 meters.
However, by using Terra Inspectioneering’s UT drone, the power company was able to eliminate the need for scaffolding assembly and removal and shorten the inspection time greatly.
Leveraging unmanned robotics not only allowed the power company to save on labour costs but the company also managed to curtail losses that it would have incurred by facility shutdown for extended periods.
The data acquired in the inspection enabled further reduction by allowing the company to formulate comprehensive chimney maintenance plans.
