Can boiler inspection be flown instead of scaffolded?
Scaffolding a furnace to look at tube walls can cost more and take longer than every other outage task combined. A caged drone puts eyes on the same tubes in hours.
Free, about two minutes, no phone number. You get an honest no when a robot is the wrong answer.
What the job actually is
During outages, crews erect scaffold inside the furnace so inspectors can examine waterwall tubes, drums and headers, then strike it all. The scaffold exists to carry a flashlight and a trained eye.
Signs it is worth automating
- Scaffold for inspection is a six-figure line in every major outage.
- Outage duration is driven by scaffold up and scaffold down.
- Most years, the inspection confirms tubes are fine.
- You inspect multiple units on a rolling calendar.
- Findings are visual first: bulges, erosion, slag, misalignment.
What the cell looks like
A caged, collision-tolerant drone with onboard lighting flown through existing openings, capturing the tube walls systematically; findings direct where follow-up contact inspection or repair goes. The outage plan changes shape: fly first, scaffold only where something was found.
When the answer is no
Read this part first
We would rather talk you out of a bad purchase than into one. If any of these describe your version of this job, the honest answer is probably not yet.
- Your authority requires contact thickness surveys across the whole surface every time; flying only the visual pass may still help, but it does not remove the scaffold.
- The unit cannot be made safe to fly: verify atmosphere, temperature and access honestly.
- You are hunting a known leak needing hands-on methods now.
- One unit, one outage: hire the flight.
What an engineer has to verify
- Acceptance of drone visual records by your inspector and insurer for this unit class.
- Access opening sizes against the aircraft envelope.
- The operator's boiler-specific track record, not their showreel.
- Actual scaffold cost per outage, so the savings claim is your number, not ours.
Safety is not on that list because it is not ours to determine. Cell design, guarding and the risk assessment belong to an independent certified integrator, every time.

Two clips of this job actually running, from two different manufacturers. Both are the makers' own marketing footage, showing a cell under good conditions with a part it was set up for, so watch them for what the motion looks like rather than as evidence of what your rate would be.
Two robots move valve bodies between inspection stations that check dimensions and surface, then separate good parts from bad.
A cobot moves its onboard camera over parts and flags the defective ones on screen as they come through.
