Stacks, silos, cranes, roofs: visual and thermal inspection without stopping production.
Stopping a line for an inspection costs more than the inspection. Working at height means permits, scaffolding and a full day. A close-range flight brings the same images down in an hour, with the plant still running and nobody exposed to a fall.
Figures for this sector
The telephoto resolves bolts and cracks from ten metres: a structure is documented without approaching beyond the safe distance.
Structures and pipework from a safe distance: the telephoto brings back detail that cannot be seen from the ground.
Two measurement ranges: −20 to 150 °C for ordinary anomalies, 0 to 550 °C for hot process surfaces. The range is chosen beforehand, because accuracy changes with it.
A plant in operation with hot surfaces in view: which measurement range to use is decided before flying.
Delamination, ponding, lifted membrane and broken rooflights mapped on the roof orthophoto, without walking on it.
Warehouse roofs straight down: detachments, ponding and broken sheets mapped without walking on them.
The route is saved and re-flown: two checks six months apart return the same framing and compare image by image.
A dense plant: the saved route returns the same framing at the next inspection.
