ABSTRACT The loading and unloading activities of container ships at the Tanjung Perak Port is imperative, as they can be carried out quickly and efficiently. These ships tend to have a high frequency of visits and possess the largest gross tonnage among ships used for the transportation of goods. The occurrence of an accident involving a container ship can have a detrimental effect on the seamless delivery of goods via sea transportation. Furthermore, the crew be adequately prepared in order to mitigate the risk. As evidenced by research on safety behaviour have not taken preparedness as a factor into consideration when addressing emergencies. Therefore, this study aims to investigate the impact of safety knowledge, motivation, and awareness on safety behaviour in dealing with emergencies on container ships in accordance with relevant regulations. A total of 180 ship crew members served as respondents and it analysed using SEM-PLS. The results showed that preparedness, including safety procedures, emergency training, and crew security culture is an important aspect in dealing with emergencies. Furthermore, this study obtained an R square value of 0.525 in the structural model, indicating that the independent variables have an influence on behaviour, and it was classified in the good category.
