    The maritime industry has been progressing towards autonomous shipping with a main barrier and scepticism being on the safety assurance of the next-generation autonomous ships. This study aims to perform a safety analysis of the autonomous navigation of a Short Sea Shipping vessel. A conceptual system for the investigated of the system is proposed as reference, and input data for the Mean Time Between Failure of the most critical components are derived from the pertinent literature. Fault Tree Analysis is employed to calculate various metrics including the probability of failure, frequency of failure, and unavailability of the autonomous navigation function as the top event. This study results identified the critical components that contribute to the failure of the autonomous navigation function in next-generation unmanned MASS.
