Abstract: The main contribution of this study is to analyse the causes of navigational accidents, regardless of the type of ship, and to investigate by using a hybrid fault tree analysis, full consistency method, and event tree analysis. We determine the accidents and their known causes between the years of 2014 and 2020 according to IMO GISIS data. Sensitivity analyses are conducted for the operational and unsafe action failures. For collisions, non-compliance with the COLREGs, insufficient lookout, storms, strong winds, and narrow manoeuvre areas causes are found to be the most critical causes. For grounding, heavy weather conditions, insufficient lookout, engine failure, strong winds, and loss of power are the top causes that the countermeasures should be taken. Inspections for the training centres, education of maritime English, more recruitment of seafarers to reduce the workload, and usage of information technology for weather incidents are recommendations for some of the managerial implications.

Keywords: maritime accidents; collision; grounding; fault tree analysis; FTA; full consistency method; FUCOM; event tree analysis; ETA.
