Abstract [en]

Qualitative and semi-quantitative reliability and risk analyses are usually performed, using inductive analysis approaches, e.g. FMEA/FMECA (Failure Mode and Effects [Criticality] Analysis), PHA (Preliminary Hazard Analysis) or HAZOP (Hazard and Operability Study). After the identification of possible failure modes or hazards, their possible effects at different system levels are estimated. In several cases the possible effects at higher system levels are very severe, indicating that the system under study is highly unreliable or hazardous. This conclusion, however, can be modified by taking into account the effect of current controls or countermeasures that can reduce the likelihood of an adverse effect or reduce the severity. Condition monitoring provides a useful risk control approach, primarily aiming at reducing the likelihood of an adverse effect. In this paper this risk control approach is described in some more detail and a proposed methodology is described. This methodology combines FMEA and ETA (Event Tree Analysis), with special attention taken to the utilization of Condition Monitoring.
