The challenge
At the Petit-Canal facility, moisture, rain runoff and coating breakdown were causing corrosion around cone-to-column connections and bolted flanges of the steel silos.
The plant needed an audit of these load-bearing points while truck-mixers and loaders kept working below.
Scope of works
- Dual-rope rope access over silo shells, cones and support columns
- Visual testing with rust grading, coating condition and connection fatigue mapping
- Ultrasonic thickness and torque checks on splice plates and leg brackets
- 100% tool tethering above live operations
Outcome
All critical connections were assessed and documented, giving the plant a clear basis for repairs. See the Arnouville audit and our NDT services.
