Andre-Michel Ferrari, Sr. Specialist – Reliability Engineering, Enbridge Pipelines Inc
This presentation introduces the basic principles of Reliability Engineering in an operating environment applied to a repairable asset such as a pump, transformer or vehicle as opposed to a non repairable component such as a bearing, gear, or lightbulb. Those principles are then applied to building a PF Curve which will eventually be used to make critical asset management decisions such as replacement, capital cost budgeting or work planning. Because a PF curve combines condition monitoring results and “end-of-life” events, two sets of calculations must be performed. The first calculation establishes the statistical model governing the condition monitoring exercise whilst the second calculation establishes the “end-of-life” model. Another key calculation involves establishing the health index on the vertical axis of the PF curve and its relation to the previous calculations. A brief example involving the construction of a PF curve for Power Transformers will be illustrated by the presenter.
