THE STUDY ON THE COLLISION AVOIDANCE SYSTEM IN AN AUTONOMOUS SHIP

Based on the concept of E-navigation-aid system for using with various hydro-meteorological conditions developed by authors, this study plans to develop an ship collision avoidance system for autonomous ship. A real-time simulator, UMS-NCKU, which is based on the 6-DOF Manoeuvring Modelling Group (MMG) model, will be con-structed and used for the numerical simulation. In this study, a numerical technique based on Nomoto’s second-order model was employed to investigate the turning characteristics of a small ship. The manoeuvring indices were obtained from numerical simulations using the Newton-Raphson method and a regression technique. There are three simple ship encounter collision avoidance cases in fast-time simulations were selected to verify the proposed autonomous ship collision avoidance system with respect to different hydro-meteorological conditions and the results were then compared with those of the ship collision avoidance steering system in calm water. © 2023 Taiwan Society of Naval Architects and Marine Engineers.
