Structural integrity assessment, repair methodologies and decommissioning planning for operating gold mine plant in Queensland.
Project Context
Mt Rawdon Gold Mine required engineering support to safely manage ageing processing assets — including stacker conveyor systems and associated structures — while maintaining production and planning for selective decommissioning.
Engineering Scope
- Structural integrity inspections and condition grading of in-service plant
- Analysis of defects — corrosion, fatigue-sensitive details, foundation settlement and misalignment
- Repair methodologies with temporary supports, lifting plans and staged works
- Decommissioning work methodologies for stacker conveyor and related structures
- Documentation for maintenance, shutdown and contractor scopes
- Peer review of critical repairs where required
How We Delivered
Engineering was developed for site realities — limited windows, production constraints and existing undocumented structures. Methodologies emphasised practical sequences, hold points and clear responsibilities between operations, maintenance and contractors.
Outcomes
- Safe continued operation with prioritised remediation
- Documented decommissioning approach for selected assets
- Reduced unplanned downtime risk through structured integrity management
