Multi-site maintenance strategy and reliability programme for a major independent upstream operator — spanning upstream production assets, compression and utilities.
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.
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.
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.
