Abstract
Starting from a systems-based statistical safety analysis, it has been noted that safety analysis in the period of operations is performed mainly in situations when accidents have not happened. Using the FMECA method, initial events screening (exclusion from the list of initial events whose effects are not significant) was performed. Benefits of the FMECA of excavator unit enable initial events list reduction for performing the ETA. The ETA methodology allows the determination of accident scenarios on the basis of initial events, for the excavator unit. One of the initial events represents the excavator unit’s disturbance, the so-called accident precursor. Safety control chart was created from which the worst initial event was determined. A new safety assessment adoption in system operation stage based on the disturbance sequence (accident scenario) modeling is proposed.
