EDF chimney NDT by wall-climbing robots: inspection lessons for asset engineers

30 Second Briefing
Wall-climbing robots from a Birmingham-based firm have completed non-destructive testing on a 200m-tall reinforced concrete chimney at an EDF facility, proving they can adhere and manoeuvre on near-vertical surfaces at height. The trials focused on remote NDT data capture on the external shell, replacing rope-access technicians for ultrasonic and visual inspection passes over large areas in a single deployment. For asset managers, the approach points to faster condition assessments, reduced working-at-height exposure, and more frequent monitoring of tall stacks and cooling structures.
Technical Brief
- Magnetic or vacuum adhesion systems (not detailed publicly) are implied to sustain attachment on smooth concrete shells.
- Remote operation keeps personnel outside the chimney’s fall and exclusion zones during inspection campaigns.
- Consistent robotic scan paths improve repeatability of ultrasonic coverage versus variable rope-access technician positioning.
- Data are captured digitally at source, enabling traceable inspection records aligned with typical asset integrity management systems.
- Reduced need for scaffold or extended rope access shortens site occupation, easing interface with live power operations.
Our Take
Within the 78 Infrastructure stories in our database, very few Safety‑tagged pieces involve robotic inspection at heights approaching the 200 m scale, so EDF’s chimney trials sit at the more advanced end of remote NDT deployment.
For operators of tall industrial stacks comparable to EDF’s 200 m structures, shifting NDT to wall‑climbing robots typically reduces the need for scaffolding or rope access, which can materially cut outage durations and work‑at‑height exposure on large power sites.
Among the 191 tag‑matched Projects/Safety/Product items, most safety innovations focus on tunnels and bridges rather than vertical chimneys, suggesting this application could open a niche market for robotic vendors targeting legacy power infrastructure.
