In near future, more congested and dangerous marine traffic environment due to the rapid marine traffics increase and ship handling difficulty by enlargement of ship size is predicted. In this paper, an navigation supporting system proposal made to enhance the safe navigation by providing the collision avoidance informations to the navigator via marine traffic environment assessment. Proposed navigation supporting system displays results of marine traffic environment assessment, degree of the dangers and gives reason of danger which is enhance situational awareness of navigator. For this purpose, results of marine traffic environment assessment which is obtained via real time assessment sent to the designated server and through the connection with navigation supporting system navigator being enable to see all those informations on the computer screen Navigator would utilize those information to make a decision in the difficult waterways and thus safe navigation could be enhanced.

This paper proposes to include engine information in Maritime Service Portfolio (MSP) for effective implementation of e-Navigation. Even though engine information is one of most important element to e-Navigation, MSP consists of mainly about navigation and communication information not included engine information. Furthermore, in reality, engine information sent from ship side such as mainly noon report and Planned Maintenance System (PMS) is too limited to make e-Navigation possibly. Therefore, Remote diagnostic structure receiving and sending data of engine information must be included in MSP for implementation of e-Navigation. Also, it has to be designed, and developed by Software Quality Assurance (SQA).

According to the Marine Traffic Safety Law, revised in 2009, Marine Traffic Safety Audit is introduced to secure the safe navigation, to prevent the marine accident and to maximize the efficiency of the port. In this audit system, marine traffic safety assessment is the most important scheme because the primary purpose of the audit system is to identify potential risk elements affecting safe navigation. Even though the reliability of audit result depends on the selection of assessment models, there are no independent assessment models for Korean coastal waters and most of models used in Korea currently are developed by foreign countries. Therefore, the development of the independent assessment model for Korean coastal water is required. This study, prior to the development of independent assessment model, aims to provide a basic data by comparing two foreign assessment models in Ulsan port area with marine accident statistics data.

Marine pilot occupational accidents during transfer to/from the ship are at the top of the agenda after several safety campaigns by IMPA and individual attemptsThere is multiple transfer method for the marine pilot, but a most common way is to use the pilot cutter. This paper aims to predict marine pilot occupational accidents before it occurs by using historical data. Since the problem depends on several variables, this paper develops a model by using the random forest method to predict marine pilot accidents before happening with the random forest method by using RStudio software

해양사고는 주로 충돌과 좌초에 의한 것으로 인적과실이 원인이다. 한국형 e-Navigation 사업은 인적과실에 의한 해양사고 저감 및 초고속 해상무선통신(LTE-Maritime)의 구축 방안을 마련하고 있다. 그에 따른 사고취약선박 모니터링 지원 서비스(SV10)는 육상에서 수집한 선박의 위치정보를 기반으로 선박의 충돌 좌초 위험도를 평가하여 선박이 위험상황을 인식할 수 있도록 정보를 제공하고 해양사고 발생 시 육상에서 조기 대응할 수 있도록 실시간 선박 위치 및 위험상황 정보를 유관기관과 공유하는 서비스이다. 본 연구에서는 중앙해양안전심판원에서 제공된 해양사고 통계연보 및 재결서를 분석하여 SV10 서비스로 저감될 수 있는 해양사고 비율을 확인하였다.

This paper presents an integrated navigation system that combines ultra-short baseline (USBL), Doppler velocity log (DVL), and heading measurements for a deep-sea remotely operated vehicle, Hemire. A navigation model is introduced based on the kinematic relation of the position and velocity. The system states are predicted using the navigation model and corrected with the USBL, DVL, and heading measurements using the Kalman filter. The performance of the navigation system was confirmed through re-navigation simulations with the measured data at the Southern Mariana Arc submarine volcanoes. Based on the characteristics of the measurements, the design process for the parameters of the system modeling error covariance, measurement error covariance, and initial error covariance are presented. This paper reviews the influence of the outliers and blackout of the USBL and DVL measurements, and proposes an outlier rejection algorithm that is robust to USBL blackout. The effectiveness of the method is demonstrated with re-navigation for the data that includes USBL blackouts.

항로표지 당국의 핵심 목표는 교통량과 위험도에 적합한 항로표지를 종합적으로 융합하여 제공함으로써 해상교통 안전 및 해양환경보호에 필요한 요건을 충족시키는데 있다. e-Navigation은 해상 항법 및 통신 신뢰도 개선에 필요한 현대화되고 검증된 장비를 통해 안전하게 항해하고자 하는 항해자의 필요에 의해 개발되었다, 위치결정에는 GNSS가 폭넓게 이용되고 있지만, 안전하고 완전하며 환경적으로 깨끗한 항해를 위해서는 기존 항로표지 계속해서 이용할 수 있도록 유지 및 진화시킬 필요가 있다. 본 논문에서는 기존 항로표지의 최신 현황을 비롯하여 기존 항로표지에 대한 기술적 관점과 항해자의 관점으로 e-Navigation 환경에서 전통적 항로표지의 역할을 검토하고, 진화 및 미래상을 제시하고자 한다.

최근 불규칙한 해양기상변화로 인하여 항해하는 선박들은 해양 기상환경에 대한 대비책이 절실한 상황이다. 해양 기상 모니터링시스템은 이러한 해양 기상환경에 대한 정보를 수집하여 주변 연안을 항행하는 선박에게 실시간 제공하므로서 해양교통 안전을 확보하기 위한 시스템이다. 오래전부터 해양 선진국에서는 항로표지시설 등에 해양기상관측센서를 설치하여 해양 기상모니터링 시스템을 구축 운용 하고 있으며, 선박의 안전항해에 많은 도움을 주고 있다. 더욱 발전된 해양기상모니터링 시스템을 위하여 국내외 현황을 분석하고 연구하므로서 선박의 안전항행과 해양사고를 예방하고, 최적의 해양기상모니터링 시스템을 위한 향후 발전방안에 대해서 논의하고자 한다.
