| Abstract |
|
In Korea, fishing ships are involved in 64.45% of all maritime accidents, with 45.8% being collisions between fishing and non-fishing ships. Fishing ships have non-fishing ships have different navigation areas and fishing methods. Causes of accidents are complicated by factors in the fishing environment and navigation. Therefore, this study analyzed physical and perceptual minimum safety distance reflecting operating characteristics of trawlers to prevent ship collisions. For this purpose, the optimal safety distance for each encounter situation was calculated through numerical analysis according to fishing ship's fishing mode and a survey on perceptions of dragged fishing ship operators. Based on collected data, one-way analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) were used to analyze differences between groups and verify their significance. Numerical analysis reflecting characteristics of fishing ship operations revealed a physical minimum safety distance of 108.23 meters. Additionally, a perception survey revealed that the required safety distance varied depending on whether the ship was navigating or engaged in fishing operations, with a tendency to demand a wider minimum distance at night and during fishing operations. Significant differences between numerical and perceived minimum clearance distances reflected operators' concerns about gear protection and variations in their empirical judgment. Results of this study can serve as a basis for developing safety zones for dragged fishing ship. They are expected to contribute to improvement of fishing ship safety in the future. Based on this study, further research should be conducted on safety distance of fishing ships according to fishing methods and safety distances reflecting various factors. |
