【 摘 要 】

The Bowtie (Papion) analysis is a qualitative risk assessment methodology that provides a way to effectively communicate complex risk scenarios in an easy-to-understand graphical format and shows the relationship between the causes of unwanted events and escalation potential for loss and damage. Bowtie can display the commands, which prevents the top event from happening first, specific to each threat and also the recovery measures, which are ready to limit the possible effects once the event top has been achieved, specific for each credible result. The purpose of the work is analysis of oil spill scenarios. Research and methodology: 1) Bowtie analysis diagram that focuses on environmental losses and damage resulting from possible scenarios; 2) Threats and control measures for the threats;3) Recovery and consequences measures. Results:1) Bowtie risk treatment tools; 2) integrated tools for risk management processes. Conclusions: The main advantages of the approach of adopting the Bowtie in the risk analysis are:a) provides a solid technique of comprehensive identification of all risk events and promote an understanding of their mutual relations; b) uses a format in the form of an easy-to-understand scheme to communicate the cause relationships and the underlying effect of more complex risk scenarios.
