Analysis of association levels of accidents causing marine pollution

OpenAlex · English

Marine accidents are one of the most important phenomena of the maritime industry since the past. In addition to causing loss of life and property, these accidents also have a negative impact on the environment. This research aims to determine the relationships between the factors in marine accidents causing pollution. In this context, 208 marine accident reports in the IHS Sea-Web database, which occurred between 1999 and 2023 and resulted in marine pollution, were analyzed by Chi-square and Cramer's V methods. According to the results of the analyses, significant relationships were found, especially between vessel flag, vessel type, and gross tonnage. High-tonnage vessels and bulk carriers, containerships and general cargo vessels were mainly flying the flag of convenience. Vessel status was the only variable that had a significant relationship with the pollution quantity. Vessels in maneuvering and on voyage are more likely to have a high amount of pollution, while the amount of pollution in accidents occurring in bunkering is low. The research findings can provide stakeholders take preventive measures and raise awareness to prevent pollution resulting from accidents.
