선박 위치오차 연구를 통한 해상교통관제센터의 기능 강화에 관한 연구

Abstract

This study outlines the mission, role, and relevant laws governing the safe navigation of passenger and merchant ships managed by the Vessel Traffic Service (VTS) center. It tested control conditions within the designated area by selecting both controlled and uncontrolled vessels. The controlled vessels included passenger ships navigating the coastal waters of Tongyeong, while the non-controlled vessels comprised fishing training ships and marine survey training ships from Gyeongsang National University, which are similar in size to coastal and offshore fishing boats. Additionally, data from two small coastal fishing boats operating in the southern sea were included in the study. The experimental setup employed ship location transmission devices and navigation recording technologies such as AIS, V-pass, ECDIS, e-Navigation, and VHF. The progress of the experiment was accurately recorded using auxiliary equipment, including ship transceivers and mobile phones. By comparing and analyzing the navigation data from each experimental ship with VTS radar control videos and GPS plotter records, the study assessed the accuracy of location errors from the ship location transmission devices and identified radio wave shadow areas within the control zone. In the event of a marine accident in coastal waters, precise location data of the incident vessel provided by the VTS center is crucial for enabling rapid emergency rescue responses to save lives and protect valuable property. The southern coast, which has numerous fishing vessels operating outside of control, features many islands and reefs and is significantly impacted by geographical and environmental factors due to rapid changes in sea and weather conditions. Errors in GNSS and human or physical factors between land-based and ship-based stations can lead to communication failures, resulting from mechanical and technical issues such as transmission and reception delays. Therefore, it is essential to address various social, economic, environmental, technical, and legal challenges related to the systemic role of the VTS center and to seek effective solutions. Specifically, to enhance the safety of fishing boats, which experience a high rate of marine accidents along the Korean coast, I strongly recommend establishing an agency or organization dedicated to fishing boat control, similar to the existing VTS center. If my research and efforts contribute to the development of maritime policing and the safety of fishing boats and fishermen, I will continue to conduct such experiments and research.
