Abstract

Accident Risk Assessment Methodology for Industry (ARAMIS) has been developed and successfully applied to prevent accidents in the chemical and process industries within the scope of the Seveso-II directive. Chemical tankers aren't subject to obligations of this directive but coincide with it both in terms of chemical products and operational procedures. We aimed to contribute to the search for a proactive approach to risk analysis in chemical-tanker operations by applying ARAMIS for the first time. ARAMIS consists of "Methodology for the Identification of Major Accident Hazards " (MIMAH) and "Methodology for the Identification of Reference Ac-cident Scenarios " (MIRAS). In the MIMAH; we assessed equipment types with Event Tree Analysis (ETA), identified critical events with Fault Tree Analysis (FTA), evaluated hazardous equipment with Vade-Mecum, identified hazards with Hazard and Operability Analysis (HAZOP), and Layers of Protection Analysis (LOPA), and we analyzed these hazards with Bow-Tie. In the MIRAS, we calculated the risk factor with the Probability of Failure on Demand calculation for each event using "Offshore REliability DAta " (OREDA), TESEO, BEVI-Guidelines, and assessed the risk with ALARP. The findings showed that ARAMIS can be used in chemical -tanker operations, and risk threshold values were low because of human errors, and basic control systems.
