From ARAMIS methodology to a "dynamic risk" monitoring system
Résumé
The ARAMIS project is believed to be able to address several goals, in particular: a) the use of state of the art methods to study processes to predict potential hazardous events and their likelihood; b) the achieved ‘transparency’ of processes that allows both the users and the regulating authorities to understand, validate and comment on risks in a consistent manner. The ARAMIS methodology first introduced the concepts of safety barriers and bow-ties, which, nowadays, are used on a daily basis by the European Industry and are considered as a valuable means to perform risk assessment and to share the results with stakeholders. However, in order to address a risk assessment usable for real time safety management a further step needs to be accomplished, namely: the dynamic monitoring of risk, i.e. how the actual status of equipment and or conditions in a moment in time can be taken into account to update the risk assessment and therefore estimate the risk exposure of the installation towards the accidental scenarios identified. This step was developed thanks to further EU funded project TOSCA that built on ARAMIS achievements. The actual risk level of an installation in respect to hazardous phenomena is in fact a property that changes over time taking into account the actual status of equipment and the management of them. The present paper explains the progress achieved towards this specific goal along with the presentation of an applied case study.
