The purpose of this study is to develop the training programme for VTS operators in Korea. The methodology used are literature and questionnaire survey. The literature, proceedings of international symposia and letters from Canada, USA, Japan and other countries were properly used and analyzed in order to compare their contents. Through the results of this study, I proposed the basic training programme for VTS operators in Korea as followings. First, the number and level of Korean VTS should be properly decided. Second, the training organization and staff should be built and appointed. Third, the VTS trainee should selected, and the training level & period should be established according to their qualification and experience. Fourth, the training should be acted by the VTS training curriculum. Fifth, The VTS operator certificate should be issued through proper test. This paper concluded as followings through the analysis of the questionnaire regarding to VTS training programme in Korea. First, the proposed curriculum were properly constructed and the independence among them was existed through the reliability and correlation analysis. Second, the difference of the curriculum importance among the questionnaire group was nearly not found through the Analysis of Variance(ANOVA). Third, the required days per each curriculum was limited to maximum 5days.

Vessel Traffic Services (VTS) operators perform traffic management tasks using VTS systems and sensor equipment designated as VTS facilities to promote the safety and efficiency of vessel traffic. The necessary VTS information for effective operations could be obtained through the additional access of various information channels other than the designated VTS facility. To unify these various information access windows, the development of the VTS cloud system is in progress. In this study, the operational information analysis for VTS was performed through VTS tasks-facility linkage analysis to identify the user required information according to the introduction of the VTS cloud system. The VTS task analysis was performed through research of the international and domestic literature, and expert interviews. The necessary information were identified and linked according to the VTS facilities. As a result of the analysis, 37 categories of necessary information were identified for internal and external information windows, and 8 information windows were selected other than the present VTS equipment. The identified user requirements would be applied to the structure design of the VTS cloud system. In the future, it is necessary to update user requirements through scenario-based user operation analysis and to conduct additional research on the system interface design.

The methods of estimation of VTS effectivenss are compared and the worldwide literature related to the VTS effectiveness is reviewed. The review suggests three potential approaches ; simulation ; synthesis of expert opinion and statistical analysis of casualties. this study adopted dissimilar approaches to estimate the VTS effectiveness to the earlier studies ; the combination of synthesis of expert opinion and causal analysis of casualty. The VTS effectiveness is derived by multiplying casualty rate reduction factors by the effect level of causal factors. The development of casualty rate reduction factors was based on the questionnaire survey and the evolution of effect levels was based on the causal analysis using functional block diagram. According to these procedures the maximum benefit to be obtained through the introduction of a VTS system was approximately 46 percent overall. The collision reduction rate was estimated to be approximately 50 percent for a VTS system with advanced radar surveillance. And 47 percent of groundings 36 percent of rammings and 21 percent of founderings could be reduced by the introduction of VTS. These figures are more or less the same to the earlier studies. The VTS effectiveness by the different causal factor groups was examined. VTS may reduce about 68 percent of causal factors classified as environmental conditions 40 percent of human factors and 35 percent of technical factors in collision accidents. As a whole 60 percent of environmental factors 41 percent of human factors and 20 percent of technical factors may be prevented by a VTS. The key variable of the effectiveness percentage is the value of weight coefficient $\delta$. Therefore differing values for this input was discussed and the impact that these variations have on the VS effectiveness noted. As the results of sensitivity analysis of VTS effectiveness by $\pm$10 percent the effectiveness is varied approximately three to seven percent by casualty type. And the value is changed roughly four to eight percent by a $\pm$10 percent variation by different sub-areas.

A concept of the "e-Navigation" was introduced in 2005 and implementation strategies are under way by IMO/IALA in the maritime safety area. Specially VTS is an important maritime traffic monitoring and aids to navigation system which is aims to improve safety, navigation efficiency and protect the marine environment. The demand of the inter-VTS networking has been increased and standardization is underway for realization of shore side collaboration for maritime safety in IALA. But there may be security problems in the inter-VTS networks if they have not proper security mechanism. The hacking of realtime ship position and sensitive maritime surveillance information caused a critical accident of vessel, human life and environment by terrorist. This paper aims to design of a secure inter-VTS network structure and related security protocol for secure sharing of sensitive maritime data.

In South Korea, a cloud-based vessel traffic service (Cloud VTS) system integrating the fourth industrial revolution technologies such as cloud and AI is currently under development in contrast to the existing VTS systems. A pilot center for at Busan VTS is being established based on differentiated technology and operational programs. The roles of operators and maintenance personnel who operate the innovative Cloud VTS system must be redefined. Additionally, a demand exists for the development of new educational programs to ensure the smooth operation of the Cloud VTS. Therefore, this study introduces the development details of a Cloud VTS system and explores educational strategies aimed at operators and maintenance personnel to ensure its safe operation.

"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.

기존의 VTS 교육훈련시설은 레이더 영상의 전시에만 의존하여 충실한 교육효과를 거두기 어려운 현실이었다. 최근에 선박 조종시뮬레이터에서 사용되던 3차원 가상영상을 VTS 관제운용에 접목하여 악천 후 등으로 인한 CCTV 활용 및 견시가 불가능한 때에도 선박의 현재 항해 상태를 직관적으로 파악할 수 있는 시스템이 개발되었다. 본 연구에서는 3차원 가상영상의 제공이 관제사의 효율적이고 신속한 의사결정을 어떻게 지원할 수 있는지를 살펴본 뒤, 기존 VTS 훈련 장비에 3차원 가상영상을 접목하여 보다 충실한 교육훈련효과를 거둘 수 있는 방안을 찾아보았다.

국제해사기구(IMO)에서 진행하는 "e-Navigation" 프로젝트의 구성요소인 해상교통관제시스템(VTS)을 정의하고, VTS 시스템간 정보교류를 위한 기술로 IVEF(Inter-system VTS Exchange Format)를 소개한다. 현재까지 국제항로표지협회(IALA)에서 개발한 IVEF에는 접속자에 대한 신뢰도 높은 인증 기술이 포함되지 않는다. 하지만 해상교통정보는 국가적으로 보안수위가 높은 정보이므로 정보 요청 자에 대한 신뢰 높은 인증이 절대적으로 필요한 부분이다. 따라서 본 논문에서는 메인 인증 서버와 IVEF를 이용하여 VTS 시스템간의 신뢰도를 높일 수 있는 인증 시스템을 제안한다.
