"93년 국내 해상교통관제시스템이 도입, '06년 진도연안VTS개국 및 '12년 여수연안VTS 개국 이후 사고 위험성이 높은 연안해역에서 선박충돌 좌초 사고 발생율은 현격하게 줄어들었다. 그러나 관제를 위한 시스템은 나날이 발전하고 있으나 인적 요인 중 관제사의 관제이력정보 등 관제정보를 공유할 수 있는 시스템은 현 VTS 시스템에서는 개발 및 도입되어 있지 않은 실정이다. 이에 따라 해양경찰에서는 '23년 11개소 연안VTS 센터 확대 구축되기 전에 각 VTS 센터 간 관제정보를 공유할 수 있는 시스템을 연구하여 효과적인 관제사의 현장업무수행 능력 향상 방안으로 활용하는 방법을 제시한다.

Although navigation systems and automatic identification technologies are in use for nautical safety of ocean vessels, ship collisions are increasing due to the growing number of overseas transportations. Since these accidents are mostly caused by the watch officers and crews' human mistakes, it is essential to develop a new set of systems to prevent such misfortunes. Therefore, we suggest a control and management system which monitors crews in order to conduct secure on-board navigation and nautical safety. We also materialized a mobile terminal system and portable device for the crews to check the status of the ship, and we designed a platform for an integrated surveillance system to assure a harmless voyage. Lastly, we attested the mutual connections of integrated safety-related data.

In maritime accidents, collisions involving fishing vessels are more frequent and severe than those involving other types of vessels. Previous cases of collision accidents caused by fishing vessels causing serious damage implied that fishing vessels maintained high speeds until just before the collision and that they collided with much larger vessels. This study investigated the correlation between the severity of ship damage resulting from fishing vessel collisions and the vessel's speed. The effective impact speed commonly used in the road transport sector was utilized to analyze ship collision accidents. The study collected collision data between fishing vessels and between fishing vessels and non-fishing vessels from accident investigation reports from 2016 to 2022. The effective impact speed was calculated for a total of 617 vessels. After using binary and multinomial logistic regression methodology, the analysis was carried out with effective impact speed as the independent variable and severity of accident as the dependent variable. The analysis revealed a statistically significant correlation between the effective impact speed and the severity of ship damage, indicating that the severity of ship damage is influenced not only by the effective impact speed but also by the tonnage of the vessel.

우리나라는 항만운영의 효율성 및 선박 안전운항을 위하여 1993년 포항을 시작으로 전국 18개의 VTS 시스템을 설치 운영하고 있으나, 최근 선박 교통량의 증가와 더불어 해양사고의 증가 원인으로 인적요인에 대해 연구 필요성이 대두되고 있다. 특히 해상교통관제 업무는 고도의 주의력과 예측능력을 요구하므로 이를 저해하는 인적요인을 분석 및 관리할 필요성이 있다. 따라서 본 연구에서는 VTS 관제실의 근무환경에 대해 설문조사를 통한 요구사항 분석과 함께 현장조사를 시행하여 분석함으로서 VTS 관제장비 및 관제석의 최적 배치방안을 제시하여 최상의 해상교통관리 체제 구축에 대하여 고찰해 보았다.

세계적으로 선박 교통량 증가와 함께 선박 사고 원인의 90% 이상을 차지하는 인적요인에 대한 심층적인 연구의 필요성이 대두되고 있다. 해상교통관제 업무는 고도의 주의와 예측능력을 요구하며 이를 저해하는 인적요인 분석 및 관리 필요성이 절실한 분야이다. 특히 관제업무는 교대근무 등의 불규칙한 근무형태로 인해 발생되는 피로와 업무 집중력 저하, 스트레스가 많은 업무이다. 무엇보다 관제 업무는 해상안전에 핵심적인 역할을 하는데, 관제사의 피로와 스트레스로 인한 업무 차질은 자칫 안전사고로까지 이어질 수 있는 위험이 존재한다. 이렇듯 인적요인이 중요한 영역임에도 불구하고 관제사들의 체계적인 스트레스 관리에 대한 방안은 미비한 실정이다. 본 연구에서는 직무스트레스 유발요인, 유발결과 및 설문조사를 통하여 관제사들의 직무스트레스 현 실태를 파악하고자 한다. 그리고 연구결과를 바탕으로 관제사의 피로, 스트레스를 관리하기 위한 방안과 더 나아가 효율적인 인적요인 안전관리 방안을 모색하고자 한다.

최근 선박의 연안 선박의 안전사고가 증가함에 따라 기존 항만 중심으로 운영되고 있던 해상교통관제센터의 관제 범위가 연안까지 확대되고 있다. 이에 따라 해상교통관제센타(Vessel Traffic Service Center, VTS) 간에 데이터 교환의 필요성도 증가하고 있다. 국제항로표지협회 IALA(International Association of Lighthouse Authorities, IALA)는 이러한 필요성을 인지하고 해상교통관제센터간 데이터 교환 프로토콜인 IVEF(Inter-VTS Exchange Format)를 제정하였다. 그러나 IVEF 프로토콜 특성상 외부 해상교통관제센터간 데이터가 전송됨으로 데이터 변조등의 위험성이 있다. 하지만 IVEF 프로토콜은 보안 관련 요소들이 미미한 실정이다. 본 논문에서는 IVEF 데이터의 무결성을 보장하는 방법을 제안한다.

In ports of Korea, the marine traffic flow is congested due to a large number of vessels coming in and going out. In order to improve the safety and efficiency of these vesse's movement, South Korea is operating with a Vessel Traffic System, which is monitoring its flow 24-7. However despite these efforts of the VTS (Vessel Traffic System) officers, marine accidents are occurring continuously in their control area. VTS Officers are controlling subjectively based on their experience due to no VTS control guideline of dangerous situation among vessels. On this paper, we listened to Busan VHF channel for 3days and analyzed the message. With collision risk model, We analyzed a moment of risk which officers advise or recommend to vessel in encounter situation, VTSO's career, and day&night.

The purpose of this study is to improve the current vessel departure control regulations to prevent traffic congestion after the lifting of vessel departure controls due to restricted visibility. AIS data was collected to analyze the traffic volume of normal traffic flow and after departure control. A statistical test was conducted to confirm the difference in traffic volume at peak hours according to whether or not departure control was used. The results of the t-test showed that there was a significant difference in traffic volume among groups of less than 10,000 tons in gross tonnage. However, the Mann-Whitney test showed no difference in traffic volume regardless of vessel control. Small and medium-sized vessels of less than 10,000 tons after departure control increased in traffic volume by 142% over normal traffic, and it was concluded that traffic congestion resulted as these small and medium-sized vessels were departing at the same time as large vessels of more than 10,000 tons. In order to prevent vessel collision accidents due to traffic congestion, it is suggested that the navigability of vessels less than 160 m or less than 10,000 tons should be improved.

According to the statistics of marine accidents occurring in Korea since the past 10 years, the proportion of small fishing boats having a gross tonnage of less than 10 tons was confirmed to be as high as 47.51% of the total marine accidents. Additionally, the trend of marine accidents involving small fishing boats has been increasing steeply compared with that of other ship types/sizes (gross tonnage); hence, countermeasures must be prepared urgently. The Korea maritime transportation authority proposed the introduction of a self inspection system to improve the ship inspection system of small fishing vessels. Futhermore the Ministry of Oceans and Fisheries recently prepared and implemented the 'Remote Method of Vessel Inspection Guidelines' to introduce non-face-to-face inspection methods. In this study, a self inspection approval system was presented as a method for reducing marine accidents of small fishing vessels. Moreover, a mobile application was developed to prepare a standardized remote method, and its effectiveness was analyzed. Resultantly, the necessity of introducing a mobile application-based ship inspection system was confirmed with the introduction of a self inspection approval system that could induce voluntary safety management in fishing vessel owners. Additionally, we confirmed that the self inspection approval system could effectively reduce marine accidents by raising the safety awareness of ship owners.

The system that covers gathering, integrating, exchanging, presenting and analyzing of information within ships and shores for the safety and security in Marine Environment is known as e-Navigation Policy. Northern Europe has been conducting research and development. It came up into a concept that deals with ship's route information between vessels as well as vessels to shores which is better known as route exchange system. The research showed substantial advantages on navigational safety by exchanging the route information between vessels in vicinity and vessels to shores. Therefore, upon the adaptation of route exchange System as a major function in integrated navigational system, the existing procedures in VTS could be changed for betterment. In this study, it was verified the effectiveness of route exchange system by the adaptation of a recent collision accident occurred in Korean coast and suggested that route exchange system which would be carried out by the discretion of VTS center in VTS area. Finally, it proposed the new functions for outstanding services and procedures of integrating traffic organization services on coastal VTS for an effective route exchange system in Korean coastal area.
