The challenge
A battery of 30 silos is under constant load from cement and clinker, plus weathering on the outside. Small cracks, wall thinning and coating breakdown can grow into structural failures if they go unnoticed.
The plant needed every silo assessed, concrete and steel, while production continued.
Scope of works
- External survey by rope access and mobile platforms; internal survey under confined space procedures
- Ultrasonic thickness of steel shells, rebound hammer testing of concrete and weld flaw detection
- Mapping of coating breakdown, corrosion and concrete spalling
- Condition logs and a prioritized repair plan for each silo
Outcome
All 30 silos were inspected with no interruption to operations, and the plant received a clear maintenance roadmap. See our NDT and inspection services and the silo stabilization case study, which shows what an inspection can lead to.
