Özet:

The aim of this study is to determine the possible causes of collision accidents and identify the contribution of possibility on top events by using Fault Tree Analysis (FTA). A total of 62 collision accidents were considered between 2005 and 2020 and detailed technical data on marine accidents were provided from accident reports obtained by Marine Accident Investigation Branch (MAIB). The study found that most of the factors (E1/Misuse of navigational tools, E3/COLREG Rule-5 (Look-out)) that had the greatest effect on the collision were mainly due to the inadequacy to keep a safe navigation watch. For that reason, the findings of the study are very important in terms of determining the strategies to eliminate the risks for future accident prevention. For further research, it is recommended that consideration be given to a longer data period, including other navigational areas. In addition, alternative risk assessment methods should be applied considering other types of vessels for better comparisons.
