Maintenance strategy development and optimisation across a portfolio of mining operations — covering diamond, platinum, coal and iron ore assets — with RCM studies for primary extraction and processing equipment.
The group operated across four commodity types with distinct asset bases and operating environments. Each commodity had evolved separate maintenance practices, creating inconsistency in approach, duplicated effort and missed opportunities to share best practice across the portfolio.
Optimal conducted commodity-specific RCM programmes for primary extraction and processing equipment across the portfolio — built on a consistent analytical framework. Group-level standards and minimum requirements were established to create consistency, and a cross-portfolio KPI structure enabled performance benchmarking.
The group achieved a step-change in maintenance consistency across the portfolio. Cross-commodity learning opportunities were identified and implemented, and the unified KPI framework gave group leadership visibility of maintenance performance for the first time.
