These days as there are growing the number of vessel sailing, diverse aquaculture industries, fishing works, and leisure activities in coastal area, the diverse communication services have been required for secure voyage information. This paper addresses the scheme for costal area service using mobile IP router with multiple interfaces. For this, this system has the wireless interfaces, such as WiBro, HSDPA, and WLAN that can provides vessels with divers communication services, and can provide the vessels with the diverse information communication services in real-time through wireless communication network installed in costal area. So this can provide the infrastructure that supplies the authorized seamless information communication services.

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 vessels, South Korea is operating with a Vessel Traffic System, which is monitoring its waters 24-7. However despite these efforts of the VTS (Vessel Traffic System) officers, marine accidents are occurring in their assigned districts and it is made a danger situation every 20minute. On this paper, we listened to Busan VHF channel for 3days and applied to collision risk model. With collision risk model, We deducted a moment which advise or recommend to vessel. We suggested a collision risk model as VTSO support system.

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 the present maritime traffic conditions of Mokpo harbor, there exist many hazardous factors which may lead to huge accidents including marine oil pollution We analyze marine traffic environments including traffic congestion, natural conditions, maritime traffic accidents in the last 10 years, the fishery status, operation of traffic routes and management of navigational aids and regulations relating ships' routeing both in and out of the country. Consequently, this work is to propose improved marine traffic system in future.

Until a recent date Wan-do Port have been made efforts to advance its marine policy toward the base of marine distribution industry. Therefore the administration of Wan-do port have been carried out many projects on improvements of harbour system very actively. The improvement of ship traffic system would be one of them. This research examined the general view of present situations of marine traffic system in Wan-do waters area and suggested improvements in ship route and anchorage.

최근 해상교통관제시스템(VTS : Vessel Traffic Service)은 항행지원정보교류가 가능한 육상국으로서 선박 통항의 안전과 효율성을 증진시키고 환경을 보호하는 e-Navigation의 핵심적 시스템으로 역할이 기대되고 있다. 최근 IALA를 통하여 국제적으로 데이터 공유를 위한 구조에 대한 연구와 표준 포맷이 정해지고 있으며 IVEF(IVEF:Inter-VTS Data Exchange Format)는 이중의 한 중요한 요소이다. 이러한 실시간의 트래픽 정보는 국가적으로 보안에 민감한 요소이나 현 규격에 정해진 보안성에 대한 규정은 다소 정해진 바 없이, 연동하기 위한 보안 규격을 다시 설계하여 상호 추진하고 연동시험을 수행해야 될 수준이다. 또한 Radar에 대한 물표 자체의 전달은 현재 고려하고 있지 않기 때문에 Track되지 않은 물표는 불필요한 많은 속성들을 같이 전송해야 하며, 레이더 물표에 대한 별도의 정해진 속성은 없는 상태여서 기존의 선박의 길이를 기반으로 비율을 고려하여 다시 재 산출되어야 가능하다. 따라서, 본 연구에서는 이러한 데이터 공유를 위한 IVEF의 규격을 검토하고 이를 보완하는 내용을 고려하여 새로운 프로토콜 및 방안을 제시한다. 이러한 구조는 VTS 시스템에서 적용 가능한 방안인지를 확인하여, 실제 적용할 수 있는 기술개발로서 방향을 정립하고자 한다.

Maritime autonomous surface ships (MASS) have a high degree of autonomy and operate autonomously along a planned route. However, when necessary, the shore remote control center(SRCC) can directly intervene in ship operations. In this paper, the operation concept of the simulator system, which can be used to educate and train shore remote control officers, responsible for monitoring the operation of autonomous ships on land and remotely controlling them in case of an emergency, is reviewed. The required functions of the simulator system that enables the operation concept are also reviewed. The major parts of the SRCC simulator system are the monitoring station and control station, which simulate the functions of monitoring the operation status of multiple MASS and the functions of the remote operation of MASS in the case of emergency, respectively. Various units to simulate the operation of MASS and traf ic ships and various objects around the MASS are included in the simulator system. The instructor operation station is the central part of the simulator system that integrates and controls the unit systems. Functionally, as conditions under which SRCC is allowed to remotely intervene in the operation of MASS, the emergency situation for remote control (ESRC) has been defined. Moreover, the required functions to cope with these ESRC conditions have been included in the simulator system requirements.
