In the SEVESO II Directive, the objectives in terms of risk management are very clear, but the remaining question is: How to reach them ? For example, there is no harmonised definition of the scenarios that have to be considered for risk assessment. Typically, the chosen scenarios (BLEVE, total loss of containment, lire in the largest tank, explosion of the largest mass of explosive, etc.) can be different according to the specific risk analysts and according to the deterministic or risk-based approach of the country applying the Directive. In this paper, the authors will share with you the main results of the ASSURANCE project, in which 7 European organisations performed a benchmark exercise for the risk analysis of a specific plant. ASSURANCE pointed out the need for further development that were achieved in the ARAMIS project. For this latter project, the authors will present the main results and the perspectives and how the ARAMIS results constitute a major step forward in the convergence of practices in risk assessment.
