Formal safety assessment (FSA), as a structured and systematic risk evaluation methodology, has been gradually and broadly used in the shipping industry nowadays around the world. Concerns have been raised to navigational safety of Yangtze River, known as China’s largest and the world busiest inland waterway. With the national development of the Middle and Western parts of China, the throughput and the passing ships in Yangtze River have been rapidly increasing during the past few decades. Meanwhile, accidents such as collisions, groundings, overturns, oil-spills and fires occur repeatedly, causing serious consequences. In view of this, attempts made in this paper are to evaluate the navigational risk of Yangtze River using the FSA concept and a Bayesian Network (BN) technique, so as to enhance the navigational safety in Yangtze River.
