Autopilot에서의 조타정보 추출, AIS를 통한 조타정보의 송수신, ECDIS에 타각이 표시되도록 프로그램을 적용하여 선회조기감지시스템을 구현하였으며, 이를 실선실험을 통하여 확인하였다. Autopilot을 작동하여 송신용 AIS를 통하여 전송된 조타신호가 수신용 AIS에 수신되어 ECDIS에 3초 이내에 표시됨을 확인하였다. 선회조기감지시스템은 선박 상호간의 충돌사고 예방에 큰 도움이 될 것으로 예상하고 있으며, VTS 관제에 있어서는 선박들의 조타 상황을 파악하여 선박의 움직임을 조기에 파악하여 관제가 가능하다. 또한, 해양안전심판원에서는 AIS를 통하여 조타정보가 저장된 해양안전종합정보시스템(GICOMS)를 통한 사고분석이 가능할 것으로 판단된다. 추후 선회조기감지시스템을 적용한 간이형 시뮬레이터를 개발하여 도선사 및 항해사를 대상으로 적용 평가하여 해당 시스템의 활용가능성, 신뢰성 등을 검증하고자 한다.

In the marine accidents judgment, investigation of truth of matters is one of important process to find out the reason of ship collision accidents. In this paper, reproduce system of ship collision accidents using ship manoeuvirng simulator technique will be introduced with which marine accidents can be easily reproduced in visual display at the case of marine accidents trial. In this system if the users select the type of ship and location of accidents, the process of ship collision will be provided in 2D and 3D display. The system also provides environmental visualizationdisplay such as fog whether and day-night view including various view angle that can be helpful to find out the reason of accidents.

Marine casualties are caused mainly by collisions and grounding, due to human error. The SMART Navigation Service is preparing a measure to reduce marine casualties caused by human error and establish an LTE Accident Vulnerability Monitoring System (SV10) to evaluate the danger of collision or grounding for a vessel based on location information collected on land. This service will also share real-time vessel locations and danger information with related agencies to enable them to respond more quickly to accidents on land. In this study, statistical reports on marine casualties and investigation reports provided by the Korea Maritime Safety Tribunal are analyzed, so the percentage of marine casualties that could be reduced using the SV10 service could be identified.

Over the last ten years, the number of entanglement marine accidents has increased more than other accident types. This study analyzed the annual statistical report of marine accidents from the Korea Maritime Safety Tribunal and Korea Coast Guard. Despite some discrepancies between data of the two organizations, it was found that marine accidents involving fishing vessels were more prevalent than those involving non-fishing vessels. In addition, the main floating materials that caused wounded entanglement accidents were fishing nets, fishing gear, and ropes, and the proportion of them was high. Foreign and domestic policies on marine plastics recognize most marine plastics as marine environmental hazards and focus on marine litter recovery and the prevention of marine pollution. The representative Acts related to the marine environment and marine litter, the Marine Environment Management Act and the Marine Waste and Sediments Management Act, recognize marine litter as a type of marine waste, and deal with the types and definition of this waste. However, clearly defining marine waste is difficult. Therefore, this study tried to examine the relevant legal system of marine litter on ship operation and suggested improvement measures. Moreover, the definition of marine litter for the safe navigation and operation of ships was clearly proposed.

As the modern maritime industry rapidly progresses through technological advancements, data processing technology is emphasized as a key driver of this development. Natural language processing is a technology that enables machines to understand and process human language. Through this methodology, we aim to develop a model that predicts the proportions of outcomes when entering new written judgments by analyzing the rulings of the Marine Safety Tribunal and learning the cause-providing ratios of previously adjudicated ship collisions. The model calculated the cause-providing ratios of the accident using the navigation applied at the time of the accident and the weight of key keywords that affect the cause-providing ratios. Through this, the accuracy of the developed model could be analyzed, the practical applicability of the model could be reviewed, and it could be used to prevent the recurrence of collisions and resolve disputes between parties involved in marine accidents.

우리나라 연안에서 육지와 섬 사이를 연결하는 해상교량은 계속해서 건설하고 있는 추세이며 해상교량이 선박의 안전한 운항에 새로운 위험요소로 대두되고 있다. 반면에 내항여객선 선장 및 항해사는 무중 레이더만 믿고 항해하여야 하나, 레이더가 해상교량의 주경간 항로와 해상교량 건너편 상황을 탐지하기 어렵다는 레이더의 한계를 인식하지 못하고, 경험과 관행에 의해 무리하게 선박을 운항하고 있다고 판단된다. 이 글은 목포지방해양안전심판원의 관할해역에서 발생한 여객선 비금농협카페리호가 신안1교의 교각과 접촉한 사건의 개요와 원인을 살펴보고, 레이더에 의해 해상교량의 주경간 항로를 식별할 수 있는 대책마련의 필요성, 선박의 해상교량 통항을 위한 최소 가시거리 인식 필요성, 해상교량 주변에 피항지 지정 및 관리, 내항여객선의 VHF청취능력 개선, VTS센터와 한국해운조합 운항관리실의 업무협력 강화, 연안 여객선의 안전문화 정착 필요성, GPS Plotter 과신 주의 등의 교훈 및 개선사항을 제시하고 있다.

As the increase in maritime traffic and leisure, the marine accident risk has increased in the domestic coast. In this study, the environment and the cause of domestic marine accidents from 1990 to 2009 have been investigated and analyzed by using the statistics issues of Korean Maritime Safety Tribunal. Based on the analysis of most domestic marine accidents sum as Engine damage, Collision, Capsizing of small vessels, we propose how to use mobile telecommunication terminals for preventing marine accidents and the best countermeasures.

In spite of being reduced the numbers of vessel registered, there are increasing the numbers of total marine accidents and collision accidents. For recent 5 years from 2008 to 2012, it was analyzed that the collision accident is highest rank by 37 % among the marine accidents and the fishing vessel is highest by 58 % in these collision accidents and also the small fishing boat under 20tons is highest by 26 % on them. Over the half of the collision accidents by 56 %, they couldn't find each other to just before the collision situation. In this result, it was known that collision accidents almost to be occurred by the poor look-out in each other. Therefore, it was suggested the requirements to the fishing vessels in a side of crew, education and exercise, and navigation equipments to reduce the collision accidents by examining the navigation patterns and concerning laws of them.

선원의 행동오류는 해양사고를 야기하는 하나의 직접적인 원인이기 때문에 이를 이해하는 것은 해양사고 예방에 근본이 된다. 선원의 행동오류를 이해하기 위해서는 행동오류를 추정하고 예측할 수 있어야 한다. 본 연구에서는 은닉 마르코브 모델(Hidden Markov Model, HMM)을 이용하여 선원들의 행동오류를 추정하고 예측하였다. 아울러 5가지 선박의 종류 각각에 나타나는 선원들의 행동오류를 서로 비교 분석하였다. 모델에 사용한 데이터는 해양안전심판원의 해양사고 보고서에 기록된 내용을 SRKBB(Skill-, Rule- and Knowledge-Based Behavior) 모델을 기반으로 분류하고 관측 수열을 생성하며 라벨링 작업을 통해서 구축하였다. 구축한 데이터를 적용하여 HMM을 보정하고 파라미터를 획득하여 선원들의 행동오류에 관한 모델을 구축하였다. 실험 결과, 선박 종류별로 선원들의 행동오류의 패턴은 서로 다르고, 이를 통해서 선박종류별 해기사들의 행동오류의 추정과 예측이 가능함을 일차적으로 확인할 수 있었다. 추후 본 연구를 지속 전개하여 해양사고 예방을 위한 인적오류의 저감에 기여할 수 있는 방안을 모색할 에정이다.
