Reliability Block Modelling – Case StudyUnderground Coal Mine - NSW, Australia
The Challenge
Our client was seeking to review the mine asset management strategies to increase the reliability of critical equipment on site. To be proactive in managing equipment performance and business risk, they sought to conduct reliability studies on the ventilation and gas drainage systems and central winder unit.
The business understood the importance of being proactive in the management of these assets. Still, it required a model that would illustrate the expected reliability of their systems, with a clear understanding of the equipment failure modes and failure rates.
The Solution
EnterpriseIS mapped the critical process flows of the required systems and validated the system design (including documentation) to understand and identify any gaps in the ‘as built’ systems. After validating the process flows and system design, EnterpriseIS collected data to support a thorough analysis of all components within each system.
An analysis was then completed across each system down to the component level to understand the different failure modes of the system, along with the failure rates of each failure mode. Finally, with all the information compiled, reliability models were developed outlining the expected performance of each system.
The Results
•Reliability block diagrams developed for each system, down to the component level
• A report on the performance deficit between each system design capability and actual performance
• A table of component failure modes and failure rates for further analysis (defect elimination and root cause analysis)
• A detailed action plan to bridge the gap between current and required performance
• A common understanding across the site on reliability block models.
