Abstract: In order to effectively reduce the risk of ship sea-bridge collision and improve the safety in bridge area, a new quantitative risk assessment method was therefore worked out. For working out the method, first, the Bow-tie model and the fuzzy set theory were combined to establish a fuzzy-Bow-tie model to quantitatively analyze the outcome events. Then the sensitivity analysis was applied to reveal the main impact factors leading to the collision. At last a risk assessment sample was given. The results show that the method based on fuzzy-Bow-tie model is suitable for quantitative assessment of risk of ship bridge collision, and that it can also provide decision support for safety management.

Key words: Bow-tie model, fuzzy set theory, sea bridge, ship-bridge collision, risk assessment, sensitivity analysis
