Thesis Summary

        Ensuring  safety  and  preventing  accidents  in  the  maritime  sector  is  of  critical  importance  for  the  sustainability  of  operations.  In
        particular, accidents occurring in offshore supply and support vessels cause both economic losses and environmental damage, as well
        as posing serious risks to human life. Accordingly, determining the underlying causes and risk factors of maritime accidents emerges as
        a  vital  necessity  to  prevent  similar  incidents.  In  this  study,  accident  data  occurring  in  offshore  supply  and  support  vessels  were
        examined and risk factors were assessed. 43 accidents recorded in the Global Integrated Maritime Information System (GISIS) and
        national and international accident databases of countries, occurring between 1990-2024, were analyzed. When the accidents were
        examined in general; 17% were seen as less serious, 25% as serious, and 58% as very serious. As a result of the accident analysis, the
        risk factors were identified and classified within the scope of the Human Factors Analysis and Classification System (HFACS). In the
        study, HFACS frameworks were integrated into the Fuzzy Analytical Hierarchy Process (FAHP). In order to analyze the human factor-
        based causes of accidents in more depth, the HFACS framework has been integrated with the Fuzzy Analytical Hierarchy Process
        (FAHP). This integration aims to make the HFACS model more quantitative by evaluating the role of human errors on accidents with
        an  analytical  approach.  The  study  aims  to  better  understand  the  human  factor-based  causes  of  accidents  occurring  on  offshore
        supply vessels and to minimize possible loss of life, property and environmental pollution incidents by improving these processes.
