Abstract
The aim of our work was the implementation of a new automated tool dedicated to risk
analysis and assessment in petrochemical plants, based on a combination of two analysis methods:
HAZOP (HAZard and OPerability) and FMEA (Failure Mode and Effect Analysis). Assessment of
accident scenarios is also considered. The principal advantage of the two analysis methods is to
speed-up hazard identification and risk assessment and forecast the nature and impact of such acci-
dents. Plant parameters are analyzed under a graphical interface to facilitate the exploitation of our
developed approach. This automated analysis brings out the different deviations of the operating
parameters of any system in the plant. Possible causes of these deviations, their consequences
and preventive actions are identified. The result is risk minimization and dependability enhance-
ment of the considered system.
