The International Maritime Organization has determined that more than 80% of maritime accidents are caused by human error. A variety of methods have been considered to reduce maritime accidents caused by such human error. Navigators operate by observing surrounding maritime situations and analyzing information using various navigational devices. This study proposes a system to ensure safe navigation by assisting navigators through the delivery of maritime safety information (MSI) between land and sea. In the future, supplementing the system through long-term on-the-ship tests is necessary by defining MSI in relation to maritime service portfolio regions.

China has integrated maritime safety system which positively and effectively ensures safe navigation and environmental protection. This paper gives brief account on maritime safety rules and regulations, adminstrations and management mechanism, navigation aids and facilities, maritime communication and GMDSS etc. China is a developing country with fast economical growth. With a long coastline of 18,000 kilometers, and 5,000 more islands, China has a fairly developed shipping industry. China also sits in IMO Council as A member. In China , there are over 200 ports with an annual hadnling capacity of over 10,000 tons of cargo ; there are over 4,000 coasters and ocean-going ships with more than 3 million seafarers of which 1/3 being officers ; there are an aggregate gross tonnage 17 million gt for merchant ships. China ranks No.5 shipping country in the world as shown by Lloyd's Maritime Information Services Ltd. 1995. The Chinese shipping industry plays an important role in both domestic transportation and foreign trade. The Chinese government always attaches great importance to maritime safety . Since 1949, and from the adoption of reform-opening policy, China has gradually formed an integrated maritime safety system.

R-Mode is terrestrial based Global Navigation Satellite System (GNSS) backup radio navigation technology which used existing maritime information service infrastructure. It has advantages on reduce the cost and reutilize the frequency resource. In this paper, we propose a method to develop a medium-frequency (MF) band R-Mode transmitting station by utilizing the currently operating Differential GNSS (DGNSS) reference station infrastructure. To this end, the considerations for co-operating the DGNSS reference station and the MF R-Mode transmitting station are analyzed. In this process, we also analyze what is necessary to configure the communication system as a navigation system for range measurement. Based on the analysis result, MF R-Mode transmitting station system is designed and architecture is proposed. The developed system is installed in the field, and the performance evaluation results is presented.

This report introduces a National Vessel Monitoring System(NVMS) within the General Information Center On Maritime Safety and Security(GICOMS) project and a national legislation system for ship's safety management in Korea. We also represent future directions of NVMS in terms of E-Navigation(E-Nav), which is the new study item for COMSAR and NAV that has been adopted from the Maritime Safety Committee(MSC) 81st session. It concludes the future E-Nav system, when it is built, that all functions of NVMS should be used by NVMS controllers as well as mariners, and we should also consider the existing NVMS infrastructure including S/W and H/W.

국가적으로 개발도상국 국제협력 지원이 추진되고 있으며, 특히 해양안전 분야에서도 교육훈련 및 정보체계 개발지원이 이루어지고 있다. 국제협력 시 적용되는 해양안전 정보시스템은 수원국에서 생산되는 해양안전정보 처리가 가능하여야 하고, 수원국에서 개발된 시스템 간의 정보 교환이 원활해야 한다는 특징이 있다. 따라서 해양안전정보 시스템은 국제수로기구에서 제정한 범용수로데이터모델 기반의 시스템 구축이 반드시 필요하다. 본 연구에서는 국제수로기구에서 개발한 범용수로데이터 모델인 S-100 표준과 범용수로데이터 모델의 운용절차에 대해 분석하였다. 또한 범용수로데이터모델의 해양안전 분야 국제협력 사례로 유출유 대응시스템에 적용하여 전자해도 기반의 유출유 대응시스템을 개발하였으며, 범용수로데이터모델의 해양안전 분야 적용 결과를 고찰 하였다.

The IMO has established a regulation for the ECDIS installation on ships based on the IHO S-57 standards. The ECDIS supports sailors in achieving a safe voyage by using ENCs and monitoring the information of their ship. However, the S-57 standards were developed as edition 3.1 and prohibited revision for more than 20 years. So, the IHO developed a new standard as S-100 into the hydrography and maritime field instead of updating the S-57 to edition 4.0. In this study, the new S-100 ECDIS was developed and verified with ENCs and the digital maritime safety information by using a ship steering simulator and by conducting an on-board sea-trial test. It evaluated the impact on ship operations if the next-generation navigation support system is introduced. Based on this research, the S-100 ECDIS will generate improvements such as safe voyages by providing various of real-time safety information and up-to-date data to ship and sailors.

In a coastal area, all of the vessels are always exposed to the potential risk, taking into the maritime accident statistics account over the last decades. To manage vessels underway safety, the characteristics of ship movements in a fairway should be recognized by VTS system or VTS operators. The IMO has already mandated the shipboard carriage of AIS since 2004, as stated in SOLAS Chapter V Regulation 19. As a result, the static and dynamic information of AIS data has been collected for vessel traffic management in the coastal areas and used for VTS. This research proposes a simple algorithm of recognizing potentially risky ships by observing their trajectories on the fairway. The static and dynamic information of AIS data are collected and the curvature for the ship trajectory is surveyed. The proposed algorithm finds out the irregularity of ship movement. The algorithm effectively monitors the change of navigation pattern from the curvature analysis of ship trajectory. Our method improves VTS functions in an intelligent way by analyzing the navigation pattern of vessels underway.

이 논문에서는 안전한 해양레저 행위를 지원하기 위한 두 가지 개인 휴대용 전자장치 개발 내용을 기술한다. 하나는 조난자를 신속히 민-관-군 동시 다발적으로 수색하기 위한 선박용 9GHz 대역의 일반 레이더 전파에 응답하는 레이더 응답장치이다. 다른 하나는 조난자의 위치를 추적하고 식별할 수 있는 900MHz 스펙트럼 확산 주파수 홉핑 방식의 송수신기와 GPS를 이용한 해상 무선식별장치 개념의 전자장치이다. 해양경찰 함정을 이용한 해상에서의 다양한 현장실험을 통하여 두 가지 장비의 성능을 확인하였다. 그리고 향후 상용화 방안에 대해서 검토하였다.
