The challenge
Caked cement inside silo No. 19 had built up on the walls and in the discharge cone, reducing flow.
The silo had to be cleaned from inside, under confined space rules, and returned to service quickly.
Scope of works
- Isolation of the silo and confined space entry permits
- Continuous gas monitoring and ventilation, with rescue standby
- Top-down removal of caked cement from walls and cone
- Handover of a clean silo with free discharge
Outcome
Silo No. 19 was cleaned and handed back with restored discharge. See also silo No. 22 at the same plant, and read about rope access in confined spaces.
