해상운송에 있어서 컨테이너화의 급진전한 발전으로 이전에 예상치 못했던 새로운 위험에 직면하게 되었다. 즉, 컨테이너 도난과 같은 모랄 리스크(moral risk), 컨테이너 멸실위험, 냉동컨테이너의 해동손해 등과 같은 위험이 있다. 이것은 컨테이너 운송인의 기업운영을 어렵게 하고 있다. 따라서 컨테이너의 해상운송시 발생할 수 있는 위험에 대해서 위험관리를 할 필요가 있다. 이에 본 논문에서는 위험관리 이론을 컨테이너의 해상운송위험에 적용하였으며, 위험분석방법으로서 하인리히의 도미노 이론을 도입하여 손해사례를 토대로 위험관리 기법의 선태문제에 대해서 고찰하였다. 이를 위해서 손해검정보고서를 이용하여 8개의 사례를 선별하였고, 각 사례별로 사고발생요인을 분서하여 하나의 요인을 제거함으로써 손실노출에 대비하였다. 그 결과 대부분의 사례에서 위험관리 기법 중 사후적 통제방안인 보험으로 전가가 이용되었음을 알 수 있었다.

The key features of maritime accidents are the change of their attributes by new risks from time to time. To prevent maritime accidents in Korea, the impacts by new risks on domestic safety environments should be identified or predicted. The purpose of this paper is to find the hazard factors by new risks on maritime safety in Korea. The meaning of new risks is the elements of accident hazard which is compiled from new or rare or unprecedented events in the worldwide maritime transportations. The problems of new risks are the lacks of optimum countermeasures to mitigate accident risks. Using the questionnaires with 152 event scenarios classified by 20 accident causes, the hazard identification and risk analysis of new risks was performed based on the Formal Safety Assessment (FSA) by IMO. A total of 22 Influence Diagrams, which is to depict the transit flows between accident causes to consequences, is used in the construction of 152 event scenarios. A total of 20 accidents causes is the same contents as the causation factors represented in Statistical Year Book for Maritime Accidents of Korean Maritime Safety Tribunals. After defining the evaluation equations to the response results of questionnaires by 46 experts, the work for risk analysis is carried out. As results from the analysis of 152 scenarios, it is known that the root cause to affect on maritime safety in Korea is the pressure of business competition and it led to the lacks of well experienced crews, the overload of vessel operations and crew's fatigue. In addition, as results from the analysis of 20 accident causes, the three accident causes are to be candidate as main issues in Korea such as the inadequate preparedness of departure, the neglecting of watch keeping in bridge and the inadequate management of ship operations. All of the results are thought to be as basic hazard factors to safety impediments. It is thus found that the optimum Risk Control Options to remove the hazard factors and to mitigate consequences required are the following two factors: business competition and crewing problems.

최근 국내에서는 연간 약 600여건의 각종 해양사고가 발생하고 있다. 해양사고의 발생에 관한 국 내외 많은 연구와 분석에 의하면 해양사고의 약 70~80%가 인적요인에 의해 발생하고 있다. 여러 인적요인 중에서도 항해사의 피로는 매우 중요한 요인이다. 항해사의 피로가 해양사고에 중요한 역할을 한다고 인식되고 있음에도 불구하고 항해사의 피로도를 정량적으로 파악할 수 있는 연구는 거의 미미하다. 따라서 본 연구에서는 해양사고 종류별로 인적요인에 의한 발생률을 분석하고, 문헌과 5점 척도를 이용한 설문조사를 통하여 항해사의 피로에 영향을 미치는 중요한 5가지 요인을 추출하였다. 그리고 ISM법을 이용하여 피로요인에 의한 해양사고 발생 위험성의 평가요소를 계층구조화하였다. 마지막으로 AHP법을 이용하여 추출된 각 피로요인의 중요도를 구하고 항해사의 피로에 의해 발생할 가능성이 높은 해양사고의 순위를 결정하였다. 그 결과 수면시간 0.386, 스트레스 0.302, 건강상태 0.139, 휴식시간 0.099, 음주 약물 0.074순으로 높은 것으로 나타났다. 또한, 인명사상사고 0.328, 충돌사고 0.308, 좌초사고 0.195, 침몰사고 0.094, 화재사고 0.075로 나타났다. 따라서 중요도가 높은 요소들을 중심으로 제어방안을 마련해야 할 필요가 있다.

완도군을 중심으로 한 서남 해안권 해상교통의 수요는 나날이 증가하고 있다. 그러나 이 같이 증가하는 여객과 관광수요에 대응할 수 있는 해상 안전 및 편의 시설 개선을 매우 미흡한 실정이다. 본 연구에서는 완도항 항만수역, 완도권내 통항 항로 그리고 여객선 운항 환경등에 대한 현황을 조사 분석하였다. 이와 함께 완도권 해상교통을 이용하는 이용자들을 대상으로 여객선 운항 환경 개선에 대한 설문을 수행하였다. 이를 바탕으로 해당 해역의 항해 위해도를 조사 분석하였으며, 여객선 운항 환경을 개선할 수 있는 제도적 장치 중에서 여객선 운임 체제개선, 타 시도 지역과 비교를 통항 개선방안 등을 제안하였다. 가장 시급한 문제는 항로상 산재해 있는 어장과 그로 인해 좁아진 항로가 여객선 운항에 가장 큰 위험요소가 됨을 알 수 있었다. 또한 여객선 운영측면에서는 타 지역에 비하여 자동화물비가 비싸 개선이 필요한 것으로 조사되었다.

In this study, the AHP (analytic hierarchy process) technique was used to analyze the risk of expected risk factors and fishing possibilities during gillnet fishing within the floating offshore wind farms (floating OWF). For this purpose, the risks that may occur during gillnet fishing within the floating offshore wind farms were defined as collisions, entanglements, and snags. In addition, the risk factors that cause these risks were classified into three upper risk factors and ten sub risk factors, and the three alternatives to gillnet fishing available within the floating OWF were classified and a hierarchy was established. Lastly, a survey was conducted targeting fisheries and marine experts and the response results were analyzed. As a result of the analysis, among the top risk factors, the risk was the greatest when laying fishing gear. The risk of the sub factors for each upper risk was found to be the highest at the berthing (mooring), the final hauling of fishing net, and the laying of the bottom layer net. Based on the alternatives, the average of the integrated risk rankings showed that allowing full navigation/fisheries had the highest risk. As a result of the final ranking analysis of the integrated risk, the overall ranking of allowing navigation/fisheries in areas where bottom layer nets were laid was ranked the first when moving vessels within the floating OWF was analyzed as the lowest integrated risk ranking of the 30th at the ban on navigation/fisheries. Through this, navigation was analyzed to be possible while it was analyzed that the possibility of gillnet fishing within the floating OWF was not high.

In the decision of a collision avoidance action for navigators and intellignet ships, it is necessary to evaluate the degree of surrounding risks effectively. We propose the new risk evaluation technique in two dimensions using Even Risk Contour on the basis of the concept of contour line. In this paper, we introduce the algorithms ofERC and Approach Velocity(AV) and show their application for avoiding traffic collision at sea.

The ships always have had the risk of collision. There are also a number of near-miss situations especially in the congested area such as port entrance, restricted waters and crossing point of the ship's route. In those areas, the navigator might have more stress than other areas. If the collision risk of decided area is calculated, it might be possible to analyse the human factors by using this data. It is also helpful for deciding a position of aids to navigation or any other system for the safety navigation. For this purpose, the model of collision risk with AIS data has been explained in this paper. The calculated result from the proposed model has been examined by using the simulation.

As economic trade between Korea and China has been encouraged with the rapid growth of Chinese economy and port competition in Northeast Asia, Korean government is trying to promote development and consolidation of ports to cope with the lack of facilities. Thus, many projects for port development have been propelled including the enactment the 'Private investment promotion law for social overhead capital 1994.' However, there are still some unsettled issues since considerable part of risk is still allocated to the Government when it has to support the private businesses in these port investments whenever unexpected problems arise. Allocation of risk among the participants - in this case especially - is a very subtle issue, however, it was revealed that not many precedent researches were done on the subject. In my previous research, I classified and analyzed 4 principle risks i.e, construction, management, financial and social risk. This research investigates the reasonable allocation of the risks among the participants using the Hierarchial Fuzzy Process. In the result of analysis, responsibility of private party is the most important and it must put the responsibility before Government' roll concerned. Also, this research displayed and proposed the direction of management method on port development in a view of minimizing risk and maximizing initiative of a private party.

Increasing global market of used electric vehicle (EV) battery encourages international firms to establish its subsidiary companies or business units specializing in battery recycling. Such kind of companies predominantly use closed loop supply chain (CLSC) for their operations of battery manufacturing and used battery recycling/reusing in global scale. However, EV battery recycling, as a relatively new industry, makes its global CLSC be exposed to various types of risks, which leads to inefficiency of supply processes and makes supply chains more complicated and vulnerable. Identifying, evaluating, and analyzing possible risks in CLSC has a great importance for optimization and increasing effectiveness for the global supply chain of used EV battery. Itwill assist to elaborate the efficient CLSC management and possible risk mitigation strategies to keep the global EV battery supply chain resilient and sustainable. This study aims to develop a conceptual framework for risk assessment in this new sector. Therefore, it will populate the framework with possible failure modes identified from various literature on EV battery recycling and closed loop supply chains so that future research can validate and utilize the conceptual framework.

해상환경 변화와 과학기술 발전 등에 따라 기존에 알지 못하던 미식별 위기가 새롭게 창출되고 있다. 새로운 위기는 새로운 해양사고를 야기하기 때문에 이를 조기에 인지하지 못하면 해양사고는 지속 발생할 수밖에 없다. 따라서 미 식별된 또는 새로운 위기요소의 식별은 해양사고 예방에 중요하다. 그리고 많은 나라에서 다양한 해양사고 분석 기법과 모델들을 사용하여 해양사고를 줄이기 위해 노력하고 있는데, 해양사고 모델 개발을 위해서는 앞으로 발생할 수 있는 위기요소들에 대한 식별 및 분류도 필요하다. 이 연구에서는 기존의 식별된 위기요소와 새로운 위기요소 식별에 관하여 기초 조사하였다.
