Navigation Safety Assessment of Ship in Rough Seas Based on Bayesian Network

This paper analyzes the rough seas weather which may be encountered during the voyage and its influences on ship’s navigation safety. This paper draws lessons from related both domestic and abroad researches about ship’s navigation safety, according to the accident causes, analyzes the factors of ship’s navigation safety affected by rough seas, determines assessment index system of ship’s navigation safety in rough seas, uses Bayesian Network to realize the assessment, and eventually works out which index contributes the most to the marine accidents of ship in rough seas.
