Client challenge
Our client was looking to improve facility performance through the implementation of a rotating equipment preventative maintenance rationalisation project, for which it spent 22k hours a year undertaking.
Our client was operating without a clear maintenance strategy and plan which aligned with current production objectives, commercial realities or equipment usage and age.
How we helped
We applied our maintenance optimisation methodology, a software enabled service. We reviewed the maintenance history, equipment criticality and derived and failure rates of critical rotating equipment before optimising the current preventative maintenance strategy of 313 machinery items.
Our team optimised safety critical maintenance against a reliability target of 95% for fire pumps and emergency generation. We also optimised maintenance for the remaining plant non-safety critical maintenance on a commercial basis.
Recommendations
Extend maintenance intervals where the failure rate evidence suggested this was possible, covering:
• Alternators.
• Combustion engines.
• Fans.
• Motors.
• Pumps.
• Fire pumps.
• Instrument air compressors.
• Turbo expanders.
• Specific equipment items were identified where repeated failures had occurred and following analysis of these failures, maintenance recommendations, were made to improve reliability.
11k
(49%) reduction in maintenance hours
The impact
• Overall hours of preventative, maintenance tasks in the scope of this study can be reduced by 11k hours (49%) on an annualised basis.
• Estimated $164k per annum cost reduction.
• Demonstrate Safety Critical Elements (SCEs) performance.
• Improved production availability.
