There are winds and waves in the sea, and they are changed frequently in accordance with the weather. By analyzing them which have the closest relation to the ship's safe voyage. evaluating the seakeeping performance and then taking a proper action, navigators should carry out safe navigation on the sea. A ship in seaways suffers continuous disturbances by irregular waves, and ship motions with irregular waves cannot be easily described as a system model which is adequate to a control system. But, in general, for seakeeping analysis, ship motions in irregular seas can be estimated by the superposition of the motion responses in regular wave components of the sea spectrum. After comparing and analyzing the winds and waves in major sea areas, this paper evaluates the navigational safety of ships on the Korean coast with potential dangerous seakeeping performance using the weather information provided by land. The conclusion is as follows : (1) It is possible that the safety of ships could be secured more accurately by evaluating the seakeeping performance of ships. (2) When the weather is bad, the departure of ships could be controlled by evaluating the navigational safety of ships. (3) When a ship is placed in commission in any area, this evaluation could be used to decide the type and size of ship in use.

Shipping of North Korea is not yet publicly well documented. Taedong River, the most important sea route of North Korea, is selected as a model study area to show how effectively a remote place can be investigated through the application of satellite-based Automatic Identification System (S-AIS) for understanding shipping and tracks of vessels which passed the lock gate in the Taedong River and visited the nearby ports on its track. S-AIS data of the year 2014 were analyzed on the basis of various time periods, country of registry and category of ships. A total of 325 vessels were observed. The ships under the flags of North Korea, Cambodia and Sierra Leone were found to be dominant in frequencies which accounted for 43.08%, 16.00%, and 8.92%, respectively. Trajectories of the 325 ships in the Yellow Sea were also checked according to the flags. It is concluded that some ships under the flags of Cambodia, Sierra Leone, Mongolia, Panama and Kiribati are regarded as flags of convenience, and ships without flag and ship type codes also comprised a remarkable portion out of the total ships.

This paper examines the applicability of formal safety assessment to the passenger ships. This is followed by an analysis of passenger ship characteristics and a proposed formal safety assessment methodology. Five interlocking steps are described to construct a safety model including novel risk assessment, cost-benefit analysis and decision-making approaches. A case study is carried out in order to demonstrate the proposed methodology. Further development in formal safety assessment in the context of passenger ship safety is finally discussed in detail.

본 연구에서는 비협약선박의 항해 통신환경에 대해 법제도적 측면에서 현황조사를 통해 문제점을 파악하여 연안선박의 항해안전을 높이기 위한 항해지원서비스를 식별하고, 식별된 항해지원서비스별로 기능요건과 운영방안에 대하여 연구하였다. 연안선박에 대한 항해지원서비스로 전자해도서비스, 연안여객선 및 위험물 운반선 등 사고취약선박에 대한 운항모니터링지원 및 항해계획지원서비스 등을 식별하였으며, 이들 서비스 구현을 위한 인프라로서 선박항법시스템, 육상지원센터 및 해상무선통신시스템에 대한 구성방안을 논의하였으며, 운영방안으로서 해사안전법에서 정의하고 있는 위험물운반선박, 길이 200미터 이상의 거대선박 및 시속 15노트 이상으로 항해하는 고속여객선 등 해양사고 취약선박에 대해 항해지원서비스 시나리오를 논의하였다. 본 연구는 우리나라 연안해역에서 종합적인 선박안전운항관리 체계를 확충하는데 기초 정책자료로 활용될 수 있으며 나아가 우리나라 연안에서 비협약선박의 해양사고 예방에 기여할 수 있다고 본다.

국내외 여객선, 크루즈선의 이용자는 매년 빠르게 증가하고, 플로팅건축물 등 새로운 해상주거활동공간의 필요성이 커지고 있다. 그러나 지난 10년간 매년 평균 15건 이상의 선박사고가 발생하고 있음에도 불구하고 아직까지도 여객선 승선객의 재난대응능력과 안전의식에 관한 연구는 매우 미흡한 실정이다. 본 논문은 국내 여객선 이용자의 안전의식을 분석하고 문제점을 파악하며, 또한 국내 기준에 맞는 피난 시뮬레이션의 기초자료가 될 데이터를 확보하기 위해 승선생활에 익숙하지 않은 일반 승선객 394명을 대상으로 설문조사를 실시하였다. 연구결과를 정리하면 다음과 같다. 여객선의 안전성에 대한 일반 승선객의 신뢰도는 32.3%로 낮게 나타났다. 선내에서 진행된 안전교육에 대해서는 불과 14.6%만이 인지하였다고 응답하였고, 배의 피난경로 확인(42.2%)과 구명정 위치 확인(40.9%) 비율도 높지 않게 나타났다. 안전한 피난 기준은 73.3%가 선내 구조에 익숙한 승조원의 지시에 따라 피난활동을 하겠다고 응답하였다.

The International Maritime Organization (IMO) has been regulating emissions by making mandatory the compliance with institutions aimed at protecting air quality such as the Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP) and Tier III. Under the circumstances, one of the response measures considered to be the most feasible is the replacement of existing marine fuel with Liquefied Natural Gas (LNG). The industry has been preemptively building infrastructure and developing and spreading engine technology to enable the use of LNG-fueled ships. The IMO, in turn, recently adopted the International Code of Safety for Ships Using Gases or Other Low-Flash-Point Fuels (IGF Code) as an institutional measure. Thus, it is required to comply with regulations on safety-related design and systems focused on response against potential risk for LNG-fueled ships, in which low-flash-point fuel is handled in the engine room. Especially, the Standards of Training, Certification and Watchkeeping (STCW) Convention was amended accordingly. It has adopted the qualification and training requirements for seafarers who are to provide service aboard ships subject to the IGF Code exemplified by LNG-fueled ships. The expansion in the use of LNG-fueled ships and relevant facilities in fact is expected to increase demand for talents. Thus, the time is ripe to develop methods to set up appropriate STCW training courses for seafarers who board ships subject to the IGF Code. In this study, the STCW Convention and existing STCW training courses applied to seafarers offering service aboard ships subject to the IGF Code are reviewed. The results were reflected to propose ways to design new STCW training courses needed for ships subject to the IGF Code and to identify and improve insufficiencies of the STCW Convention in relation to the IGF Code.

This study aims to identify the degree of safety when mariners take their actions in several different situations. We have carried out many experiments to observe mariners' behavior and then measured the safety level based on their actions to avoid dangerous situations of ships collision. One of the most important actions that mariners have to take, either as their daily routine or when they are in a collision situation and then want to avoid that situation is the lookout. In this paper, behaviors on the lookout have been defined as a standard sequence of three steps which are "time of first detection", "time of recognition as risky vessel" and "time of starting avoiding action", and the suitability and applicability of the definition have been shown. And also we propose the risk assessment on ships collision and the recommendation for reducing ships collision at sea. Some analyzing results and the application of the results are reported. By combining these knowledge and some systematic studies, we propose the risk assessment on ships collision and the recommendation for reducing ships collision at sea.
