Shutdowns are a critical part of mining operations. They allow teams to inspect, repair, test and recommission equipment that operates under extreme pressure and harsh conditions. Poor planning or testing errors during a shutdown can lead to costly delays or safety incidents.
Here’s how proper pressure testing and commissioning help minimise risk during mining plant shutdowns.
The Importance of Shutdown Planning
A shutdown begins long before the equipment stops operating. Planning includes:
- Identifying equipment requiring testing
- Assessing pressure vessels and pipelines
- Scheduling tasks to minimise downtime
- Ensuring availability of skilled technicians and mobile equipment
Good planning ensures the shutdown proceeds safely and efficiently.
Pressure Testing in Shutdowns
Pressure testing is performed to:
- Verify system integrity
- Confirm repairs
- Detect leaks before startup
- Ensure equipment is safe under operating pressure
Hydrostatic testing is the preferred method for most mining applications because of its safety and effectiveness.
Commissioning Activities
Commissioning during shutdowns may include:
- Flushing and cleaning pipelines
- Drying systems to remove moisture
- Calibrating PSVs
- Completing documentation for regulatory compliance
- Performing integrated testing before hand-over
Each step reduces risk and ensures a safe return to service.
Working in Remote Areas
Mining sites, especially in WA, often require:
- Mobile testing units
- FIFO technicians
- Self-contained equipment
- Adaptability to environmental conditions
Partners experienced in remote mobilisation reduce delays and ensure field readiness.
Documentation & Traceability
Shutdowns must be supported by clear documentation, including:
- Test reports
- Calibration certificates
- Inspection checklists
- Commissioning plans
This documentation provides proof of compliance and protects operators during audits.
