The challenge
Silos, conveyor gantries, transfer towers and support structures at the Ndola plant had been in heavy service for years. Vibration, dust deposits and weather were causing corrosion of steel profiles and wear at connections.
The plant needed a survey of all its elevated assets without scaffolding and without stopping logistics.
Scope of works
- Mobile dual-rope rope access rigging on primary steel nodes
- Visual testing (EN ISO 17637) of columns, truss chords, chutes and bolted splices
- Mapping of coating failure, oxidation and mechanical wear
- 100% tool and camera tethering over live roads and equipment
Outcome
The plant received a structured condition record of its elevated assets, ready for maintenance planning, with zero production downtime. A similar survey was carried out at a cement plant in Lusaka. See our inspection services.
