The current AIS network and. system are run on a full scale with 22 ground stations and. 11 operational systems, completing a nation-wide, integrated network However, currently it needs to manage sea traffic by linking AIS to VIS which 1vs a limited service area due to restricted radar detection zones in harbors or coastal areas. Accordingly this study analyzes the current status of the AIS system and. proposes technological and. operational improvement plan of the current AIS system through investigating the actual conditions of the AIS system and. its operations.

본 연구에서는 해상교통관제제도(VTS)가 적용된 연안해역에서 해상통항흐름에 영향을 미치는 요소를 알아보고자 하였다. 본 연구의 목적을 달성하기 위해 해상교통환경조사는 2007년도부터 2012년까지 어장, 어로활동 및 해양구조물에 대한 마로해 인근해역에 대해 현지 조사방법을 사용하였다. VTS에서 제공하는 서비스종류에 대해 국제표준과 국내 적용 규정을 비교하고 2011년 연안해역에서 제공된 서비스에 대해 분석하였다. 동 해역의 해상교통흐름은 레이더와 선박자동식별장치 정보를 시공간적으로 중첩시켜 최근 6개월간 흐름패턴을 조사하였다. 연구 대상해역은 서남해 진도 인근해역($3,800km^2$)으로 통항분리제도와 탱커선통항금지해역 및 다도해해상국립공원을 포함하고 있다. 연구결과 연안해역에서 제공되는 서비스를 통해 해양사고를 18% 감소시켰다. 서비스 제공수준은 비정규분포를 보이며 공정능력은 향상된 것으로 나타났다. 안전한 해상교통환경 유지하기 위해 정기적인 연안해역 모니터링 및 관리체계의 확립에 대한 대응이 요구된다.

At recently, Oil spill accident of large size oiler that happen domestic and outside the country is occured to social impact us as well as economical damage in sea environment. Also, because spread extent of pollution accident is reaching harbor, bay and close water areas, as necessity that traffic control ships are sea place. VTS is changing to concept that control space is magnified gradually. Our country is operated to 14 harbors which is control center. But abroad is operating coastal VTS that do main waterway and coastals to authority dimension. Therefore, necessity that traffic density of ship manages high coastals and ship traffic of waterway to our country is risen. This paper is execute sea traffic survey at Mokop sea areas and sea casualty occurs. It proposal that coastal VTS center field of most suitable and position of radar site.

급변하는 항만의 교통특성과 이용자들의 정보서비스 욕구에 발맞추어 해상교통관제 운영기법이 변화하고 있으며 차세대 다기능 해상교통정보시스템과 같은 새로운 기술이 개발되는 등 해상교통물류체제의 혁신이 이루어지고 있다. 이에 따라 세계 각국은 해상교통관제구역을 항행하는 선박의 질서유지 및 안전사고 예방과 사고 발생 시 신속한 대응조치를 위하여 해상교통관제사의 인력양성 및 인력관리에 많은 노력을 기울이고 있다. 국내에서도 선진해양교통행정을 위하여 분산된 해상교통관제 기능일 일원화 되어감에 따라 새로운 해상교통관리 체제의 효율적인 운영을 위하여 해상교통관제사들의 지속적인 훈련의 필요성이 대두되고 있지만 교육제도의 인지, 여건, 장비보급의 부족, 다양한 상황에 대한 교육시나리오의 부족으로 인하여 시뮬레이터를 이용한 교육이 효율적으로 이루어지지 못하는 문제점이 발생하고 있다. 본 연구에서는 해상교통관제사들의 교육을 위한 국내 외 규정을 분석하고 교육현황 및 해상교통관제사들의 요구사항을 파악하여 해상교통관제시뮬레이터를 이용한 교육의 개선방안을 제시하고자 한다.

Nowadays, it is planning to establish a coastal VTS in Korean southern coastal waters in order to enhance the safety of vessel traffic and to protect the marine environment. But, it surely needs over ten billions Won to establish, operate and maintain the above mentioned coastal VTS. Therefore, this paper proposes the VTS cost-benefit analysis model to confirm the reasonability and decide the priority of the project. This model has three distinct processes. Fist, it is the identification in qualitative terms of the effects of a given proposal. Second, it quantify the specified effects in physical terms. Third, it is the evaluation of the total effects of project. The proposed model in this Paper will contribute to the confirmation and the priority of the project in future.

Vessel Traffic Service (VTS) increases the efficiency of maritime traffic in terms of reducing marine accidents and the efficient use of port facilities. This means that ports and waterways have their own capacities and can be safely adapted to their capacity through proper traffic management of the VTS. Proper traffic management can reduce the number of vessels and unnecessary waiting in ports, which can lead to economic benefits of ups and port terminals. On the other hand, Korean ports and waterways have restrictions on the maximum speed for safety, but there is no restriction on the minimum speed. However, ships that operate at low speeds in ports and waterways may be able to occupy long periods of operational routes, which may impede efficient port operation. Therefore, the purpose of this study is to propose the minimum speed of ship for efficient port and waterway use. To this end, we reviewed the current laws and systems and proposed the appropriate minimum speed in the waterway using the theory of queue.

2010년대에 들어서며 산업과 행정 등 전반 분야에 있어 주요한 아젠다가 되어 있는 빅 데이터는 산업화를 거쳐 전산화의 장벽까지 넘어선 각 분야에서 혁신적인 데이터 활용을 통해 새로운 가치를 창조하고 있다. RADAR 및 관제설비의 도입으로 고도화된 VTS의 관리 체계는 관제 서버의 구축과 선박의 선박자동식별장치(AIS)의 정착 등 항해설비 발전을 통해 전산의 장벽을 하나씩 거둬가고 있다. 이제는 실시간으로 수집되는 선박 교통 데이터를 통해 해사행정의 새로운 가치 창조를 모색해야 할 시점이다. 따라서 본 연구에서는 예시를 통해 빅 데이터의 개념을 정리하고 해상교통관제를 비롯한 해사행정 전반분야와 해운, 항만, 선박 사업자 전반에게 효율적인 업무 지원을 도모할 수 있는 모델을 제시하고자 하였다. 본 연구결과가 VTS 발전 방안으로 활용되어 제도 개선에 기여할 것으로 기대된다.
