The Aegean Sea is risky for marine accidents due to its geography and dense vessel traffic. Revealing the patterns of marine accidents in the region is essential for preventing such accidents in the future. With this motivation, this study analyzes the data on maritime accidents in the Aegean Sea Turkish Search and Rescue Region. For this purpose, the descriptive analysis of the 576 marine accidents in the region between 2001 and 2020 was accomplished. Moreover, by applying hypothesis tests, the relationships between the factors that affect the occurrence of marine accidents were investigated. As a result, the most common contributing factors to the event of accidents were revealed. The relationships between the variables of the data set were determined. Accordingly, the type of ship with the most accident are yacht/recreational boat. Hull/machinery failure is the most common type of accident, and summer is the most frequent season for maritime accidents. It was revealed that there are significant relationships between the variables such as the type of accident, the sub-region where the accident occurred, the time of the accident, and the ship type. Finally, deficiencies were evaluated, and suggestions were made for more effective investigation and prevention of accidents.

Öz Comparative Analysis of Dangerous Liquid Cargoes Transportation: A Study on Bulk Chemicals and Tank Containers Abstract Dangerous liquid bulk cargo transportation by sea is a controlled and managed operation through a lot of regulations due to transported cargoes involved which require a high level of attention. Chemical tankers and tank containers are two of the most common transportation ways of transporting dangerous liquid bulk cargoes by sea. While some of the liquid bulk chemical traders transport their cargoes either in chemical tankers

It is crucial to ensure food security to continue the sustainable nutrition of the world population. Food losses in the global food supply chain pose a significant risk to food security. Especially foods that require cold chain logistics are prone to deterioration and eventually food losses. Therefore, cold chain logistics processes require operational expertise and specialized equipment. Reefer (refrigerated) container is the most used cold chain transport equipment for perishable foods requiring atmospheric control. Analyzing operational and hardware-related causes and implementing relevant countermeasures are necessary to prevent food losses in reefer containers. With this motivation in the study, the relationships between the factors causing food losses in the reefer containers were evaluated qualitatively and quantitatively via the model built using the Fuzzy Bayesian network method. The findings indicate that the most critical root causes of food losses in reefer containers are excessive time off-power, inappropriate preload conditions, and refrigerant faults, respectively. Moreover, the riskiest combination of factors that causes food loss consists of excessive time-off power, refrigerant faults, and adverse weather conditions during navigation and in port. When the existing legal framework and professional practices are examined, in light of the results of the study, the following will be recommended: Establishing minimum standard and maintenance arrangements for cooling systems, ensuring safety margin in the shelf life of the foods carried in the reefer containers, making mandatory the automatic temperature recordings systems, and increasing the number of personnel specialized in product types and transportation. The study results will benefit supply chain stakeholders for process planning and implementation to mitigate the risk of food losses in reefer containers. Practical applicationsThis study examines the factors causing food losses in reefer containers from loading to discharge. The findings indicate that the most critical root causes of food losses in reefer containers are excessive time off-power, inappropriate preload conditions, and refrigerant faults, respectively. When the existing legal framework and professional practices are examined, in light of the results of the study, the following will be
