Portland General Electric has recently completed a number of Reliability Centered Maintenance studies at their Boardman generating facility. Although the predicted results are impressive Portland General Electric is simply using Reliability Centered Maintenance as the tool to initiate a change in their maintenance culture.
The development of asset strategies and a zero based budget maintenance aligned to business goals is important for organisations seeking optimal asset management. The iron ore miner presented in this case study took over operations and maintenance of an existing crushing facility which had very few historical records and challenged themselves to achieve reliability excellence.
This paper presents a Reliability Centered Maintenance and Reliability Block Modeling approach to evaluating optimal service regimes and fleet sizes. Once complete the models can be used to predict budgets, maintenance labour and resource requirements and spares usage.
