Marine Accidents continue to occur at this point when innovations are expected in the ship and maritime industries due to the Fourth Industrial Revolution. In the event of such a marine accident, the captain, who is ultimately in charge of the vessel, demonstrates the right leadership and takes optimal measures to minimize the occurrence of accidents. You could, but the opposite could happen. This is not limited to the captain, but can also happen to the mariners depending on where the accident occurs. Therefore, in the event of an emergency, it is necessary to maintain the best efforts in enhancing awareness and competence to respond to emergencies so that mariners, including the captain, can focus on minimizing accident damage through good situational awareness and accurate decision-making. This study investigated the causes and occurrences of marine accidents in the last 5 years, and investigated and analyzed the importance of emergency response and emergency response competence that caused the accident. Besides, the current state of education related to emergency response, which was applied to domestic law along with the minimum standards for emergency response-related competence under international agreements, was investigated and compared with international standards. Also, this study intended to present a plan to improve the awareness and competence of emergency response of the mariners through the analysis of emergency response-related awareness surveys for the mariners currently on board and land workers of related organizations related to the shipping company. Many factors have been checked and identified in each chapter. Based on this, the keyword of this study is to suggest to the mariners what improvements are needed to strengthen emergency response competence. Chapter 1 described the background and purpose of the research, the contents, and methods of the study. Chapter 2 confirmed the relationship between the causes of marine accidents and the status of accidents by type of accidents and human factors over the past five years to determine which accidents are occurring in the ocean. Besides, it was intended to present the need to focus on minimizing accident damage through the definition and type of emergency response competence, investigation of inappropriate emergency response accident cases, and improvement of emergency response competence by the specificity of marine accidents. Chapter 3 identified the current status of how the minimum standards for competence in international conventions related to emergency response are organized by the rank of the mariners. It was also investigated whether Korea's emergency response-related curriculum was implemented in compliance with international standards. Chapter 4 surveyed the need to strengthen emergency response competence of the mariners on board, and land workers working in related organizations. and analyzed the results of the survey using the statical analysis program, SPSS, to find ways. Chapter 5 drew out the findings of each chapter and the conclusions analyzed in the survey and presents the limitations of this study and the direction of future research.
