Recorded Webinars: Site Safety Index™ Impact on Failure Rates and PFDavg
Several field failure studies, have shown that failure rates for the same product vary from site to site. The ratio ranged from 1.2X to 2X based on data to date. Therefore we conclude that random failures can be divided in to two categories – product specific and site specific. The differences seem to be related to site variables that some have called “Safety Culture.” exida defines this variable as the “Site Safety Index (SSI).” This webinar will provide an overview of the impact of SSI on random failure rates, realistic PFDavg calculations, and the impact of a good safety culture on life cycle cost.

Recorded Webinars: FMEDA Predictions and OREDA Estimations for Mechanical Failure Rates: Explaining the Differences
This presentation describes the distinction between failure rate prediction and estimation methods in general.
It then gives details about the procedures used to obtain dangerous failure rates for certain mechanical equipment using FMEDA predictions and OREDA estimations.
The results of the two methods when applied to specific equipment combinations are compared and, when differences in the results exist between the two methods, plausible explanations for the differences are provided.
The relative merits of each method are discussed.
