The Challenge

The operator managed multiple upstream production sites with inconsistent maintenance practices, limited CMMS utilisation, and high unplanned maintenance costs. Production reliability was below target and a structured, risk-based approach to maintenance was needed to improve availability and reduce lifecycle costs.

Our Approach

Optimal conducted a baseline assessment of maintenance maturity across all sites, identifying critical gaps in task coverage, data quality and planning effectiveness. A unified RCM-based maintenance strategy was developed, with site-specific implementation plans accounting for each location’s equipment profile, environmental conditions and operational constraints.

What We Delivered

  • Maintenance maturity baseline across all upstream production sites
  • RCM-based maintenance strategy covering production, compression and utility systems
  • CMMS data population and work order workflow improvement
  • KPI framework for maintenance and reliability performance tracking
  • Site-level implementation roadmaps with prioritised action plans

Outcome

The programme delivered measurable improvements in planned maintenance compliance and reduction in reactive maintenance backlog across the portfolio, with the CMMS becoming an active management tool rather than a record system.
