#ndt Industrial chimneys require regular inspection to assess their structural integrity. Normally a person will examine the exterior or enter the stack by rope access. This operation requires a scheduled or unscheduled shutdown and poses a safety risk for the inspection team. Drones, or UAVs, up until now have only been used to examine the exterior of chimneys, however Versatol has disrupted the chimney inspection market by developing a method to robotically inspect the interior of a stack.
