A Study on the Estimation Method of Risk Based Area for Jetty Safety Monitoring

Abstract

Abstract:Recently, the importance of safety-monitoring systems was highlighted by the unprecedented collision between a ship and a jetty in Yeosu. Accordingly, in this study, we introduce the concept of risk based area and develop a methodology for a jetty safety-monitoring system. By calculating the risk based areas for a ship and a jetty, the risk of collision was evaluated. To calculate the risk based areas, we employed an automatic identification system for the ship, stopping-distance equations, and the regulation velocity near the jetty. In this paper, we suggest a risk calculation method for jetty safety monitoring that can determine the collision probability in real time and predict collisions using the amount of overlap between the two calculated risk based areas. A test was conducted at a jetty control center at GS Caltex, and the effectiveness of the proposed risk calculation method was verified. The method is currently applied to the jetty-monitoring system at GS Caltex in Yeosu for the prevention of collisions.

“…In other words, how to identify them effectively becomes an important issue related to safety. Meanwhile, ship crews and vessel traffic service (VTS) supervisors also have to identify banks, shoals, rocks and channel structures in order for them to avoid possible grounding and collision incidents with harbour facilities (Mazaheri et al, 2014;Nam et al, 2015).…”
