In spite of advanced navigational devices and reinforced mandatory standards of officers' education, the number of ship's accidents are increasing. The accidents caused by minor license officers are more than the number of accidents caused by superior license officers. There are many cases of collisions in the past 5 years released on Marine Accidents Inquiry Agency. Especially, officer's negligence from the consequences of the neglect of any precaution which may be required by the ordinary practice of seamen is the main reason behind ship's collisions. For reducing ship's accidents caused by human error, this paper suggests to develop effective training program using analysis date of domestic and foreign education system as a reference.

The fisheries resource in waters under the jurisdiction of Korea is being endangered by unlawful fishery. The Korean government exerted great efforts to establish the public order of water, but the number of the exposed unlawful fishing violations has increased for last 10 years. The system to guide fisheries regulatory noncompliance of Korea is limited to the use of fishing guidance patrol boats. For strength of monitoring and surveillance systems, the government needs to phase in Vessel Monitoring System. But there are some studies for that. The defects of present monitoring practice can be drawn from the facts described above. The qualification of the fishery control official one of most important element of fishing control system, is defined as any officer who is charging on fishing. For clear law enforcement the qualification should require considerable experience and knowledge. Korean coast guards have problems on guiding unlawful fishing violations because of the absence of administrative authority by comparison with the fisheries guiding officer, who has both authorities on administration and jurisdiction. To draw some judicial problems this research presents a analysis on the fishing control system. The research suggests the improvements to compensate the defects.

Objective: The purpose of this study is to measure the workload of Korea coastal ship crew members, to investigate whether they are following work-break time regulations and to identify the main causes of their workload. Background: According to the US Coast Guard, about 33% of human casualties are reported to be due to fatigue, and 30% of marine casualties reported by the British Marine Accident Investigation Agency (MAIB) are attributed to crew fatigue. But the coastal ship are not managed for business hours and breaks despite the harsh environment. Method: The workload of duty crew members on the 100 domestic coastal vessels was measured. It was also investigated whether they are following domestic and international work-break time regulations. Finally, the marine accidents resulted from the fatigue of the crew was analyzed. Results: As a result of workload analysis, the workload on the 42~62% of the vessels exceeded the standard of working time on the related regulation. The workload increased with the number of inbound and outbound ports. Especially, in the system where there are two seafarers, the workload exceeded the working time requirement. As a result of the marine accidents analysis on 100 vessels, it was found that collision and grounding occurred due to fatigue, workload and drowsiness in 7 marine accidents out of 30 marine accidents. Conclusion: It is necessary for the shipping companies to introduce an operation management manual for the management of the crews' workload and reasonable crew arrangement. It is also required for crew members to easily record work times and for shipping companies to manage the record. It would be possible to prevent many marine accidents by providing adequate rest to the crews and flexibly adjusting their working hours. Application: The results of this study can be used as fundamental data to manage crews' fatigue and to make job management manuals.

This paper treats optimal route assessment system at seaway based on weather forecasting and wave measurement through observation. Since early times. captain & officer have been sailing to select the optimum route considering the weather ana ship status condition empirically. However. it is rare to find digitalized onboard route support system whereas weather fax or wave and swell chart are utilized for the officer. based on officer's experience. In this paper, optimal route assessment system which is composed of voyage efficiency and safety component is introduced. Optimum route minimized ETA (estimated time of arrival) ana fuel consumption is evaluated for efficient voyage considering speed loss and power increase based on wave added resistance of ship. In the view point of safety, seakeeping prediction is performed based on 3 dimensional panel method. Basically. the weather forecast is assumed to be prepared previously in order to operate this system.

In the current situation where clearly the ship officer is avoiding boarding, the purpose of this study is to investigate the satisfaction of onboard training in shipping companies during the COVID-19 situation and to suggest plans to improve onboard training. Furthermore, by improving satisfaction, students of maritime university can improve their career awareness as a ship officer in the future. The survey was conducted with the cadets of Mokpo Maritime University after completion of onboard training in shipping companies. The questionnaire contains seven factors: education administration, education contents, officer, facility, education ef ect, education satisfaction and career awareness. The survey analysis results indicated that the satisfaction with education administration and education effect was relatively low, and the satisfaction differed by gender and vessel type. In addition, hypothesis verification revealed that the education contents did not have a positive effect on education satisfaction and career awareness. Furthermore, a great correlation existed between education satisfaction and career awareness. We suggested that education and promotion must be improved before onboard training. In addition, the officer must be educated on the method to teach cadets and establish a training plan such that the officer can systematically guide the cadets with an educator mindset.

The congestion situation of Korea's port is further inclining due to the number of arriving and departing vessels and increase in the size of the size. Indicators for assessing whether the Vessel Traffic Congestion is called the Marine Traffic Congestion and it is used as a diagnostic entries in the Maritime Traffic Safety Audit System. In the diagnostic system, 6L (longitudinal) X 3.2L (transverse) is used as ship's domain in cases of harbor. This study is to determine the safety distance of the VTS officer and the ship operators by targeting the Busan harbor, which has the most number of ships that arrive/depart in Korea and listen to the communication of the VTS and calculate the communication time of the VTS officer and the ship operators for 7 days. By utilizing the distance communication port, the safety distance between the controllers and the ship operators is derived. It can be used for basic information of VTS Officer and Ship's operator's Safety distance in Busan port's in&out harbor.
