As in many other sectors, accidents that lead to deaths, injuries, environmental pollution, or material damage occur in the maritime sector. Maritime transportation operations, which constitute the backbone of the maritime industry, involve serious risks by nature. Although many safety measures are implemented to eliminate these risks or reduce them to acceptable levels, the number of accidents that occur in maritime operations is quite high. Within the scope of the present study, errors in anchor handling operations (AHO) and their outcomes were analysed using the fuzzy bow-tie method. The findings of the present study can be used by marine experts (maritime s researchers, ship masters, ship owners and port state officials) to reduce potential risks during AHO operations and increase maritime safety.
