Prediction of Maneuverability in Shallow Water of Fishing Trawler by Using Empirical Formula

The length between perpendiculars (LBP) of most fishing vessels is less than 100 m. Thus, they are not subject to the International Maritime Organization (IMO) maneuverability standards, affecting research on maneuverability. However, upon referencing the statistics of marine accidents related to vessel maneuvering, the number of marine accidents caused by fishing vessels is 3 to 5 times higher than that of merchant ships. Therefore, systematic and consistent research on the maneuverability characteristics of fishing vessels is surely required. In particular, a fishing vessel frequently enters and departs from the same port and often sails at high speed due to familiarity with the characteristics of the situation, which may cause maneuvering-related accidents. In this study, the maneuverability of a fishing vessel in shallow water was predicted using an empirical formula. The results of this study are expected to not only be of great help in conducting simulations when analyzing marine accidents involving fishing vessels, but will also provide unique parameters of fishing vessels that lead to developing autonomous vessels.

Automated summary

Most fishing vessels have a length between perpendiculars (LBP) of less than 100 meters, not subject to IMO maneuverability standards, but their accidents are 3 to 5 times higher than merchant ships. Research on the maneuverability characteristics of fishing vessels is necessary for safety and potential development of autonomous vessels.
