Client challenge
Our client was looking to improve facility performance through
the implementation of a rotating equipment preventative
maintenance rationalisation project, for which they spent 22k
hours a year undertaking.
They were operating without a clear maintenance strategy
and plan which aligned with current production objectives,
commercial realities or equipment usage and age.
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.
Our 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
Powerful results
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.
49%
Our approach achieved a 49% reduction in maintenance hours - saving 11,000 hours.
