내항성능 해석 기반의 선박 해양활동지수에 관한 연구는 연근해에서 활동하는 30톤이하 선박에 대해 해양기상신호표지 정보 및 내항성능 해석 정보를 이용해서 선박의 안전한 해양활동 대책을 연구하는 것이다. 해양사고는 매년 증가 추세에 있으며 특히, 연근해 활동 소형선박의 사고가 해양사고의 많은 부분을 차지하고 있고 이러한 선박은 복원성 승인 및 유지 제외 선박(길이 24m 미만)으로 대부분으로 건조 시부터 폐선 시까지 해양활동에 대한 안전대책이 부족하여 사고로 인한 사망, 실종 등 인명손실이 많이 발생하고 있다. 선박의 해양활동에 가장 큰 영향을 미치는 해양기상정보는 여러 기관별 목적에 맞게 수집되고 있으나 활용도가 떨어지고 실제 기상과 다를 수 있으며 지역 및 지형에 따라서도 기상여건이 상이하므로 현지 실시간 기상정보를 활용한 선박에 대한 적극적인 안전한 해양활동 정보 지원이 필요하다. 이 연구에서는 파고와 풍속 및 선박의 내항성능 해석 정보를 이용하여 30톤이하 선박에 대한 안전한 해양활동 대책을 강화하고자 함이다.

The Marine Safety Culture Index (MSCI) was developed in the year 2018 for objectively assessing the public safety culture levels and for incorporating it as data to spread knowledge regarding the marine safety culture. The method for calculating the safety culture index should include issues that may affect the safety culture and should consist of appropriate attributes for estimating the current status. In addition, continuous verification and supplementation are required for addressing social and economic changes. In this study, to determine whether the questionnaire designed by marine experts reflects the people's interests and needs, we analyzed 915 marine safety proposals. Text mining was employed for analyzing the unstructured data of the marine safety proposals, and network analysis and topic modeling were subsequently performed. Analysis of the marine safety proposals was centered on attributes such as education, public relations, safety rules, awareness, skilled workers, and systems. Eighteen questions were modified and supplemented for reflecting the marine safety proposals, and reliability of the revised questions was analyzed. Furthermore, compared to the previous year, the questionnaire's internal consistency was improved upon and was rated at a high value of 0.895. It is expected that by employing the derived marine safety culture index and incorporating the improved questionnaire that reflects the requirements of marine experts and the people, the improved questionnaire will contribute to the establishment of policies for spreading knowledge regarding the marine safety culture.

This study proposes a methodology for estimating the appropriate capacity of anchorage for ports requiring the establishment of waiting anchorage and then applying the methodology to the ports in Jinhae Bay to compare it with the anchorage capacity of major ports in Korea. To estimate the appropriate anchorage capacity, the "Anchorage Capacity Index" was used, which was calculated from the "Total Gross Tonnage" and "Simultaneous Anchoring Capacity". The calculations were made according to the anchorage capacity index of 0.89 of the target harbors. The adequate anchorage capacity index for the new waiting anchorage was analyzed at a level of 6.0. If the concept of anchorage capacity index suggested in this study is reflected as a new design criteria of waiting anchorage, it will be helpful for the safety of berth, safety of anchorage and effective operation of harbor.

In this study, the specialized marine industry in the area (Incheon) of the case study was identified and the issues related to the current status of marine space utilization were diagnosed. Marine space utilization was selected as the specialized marine industry activity in Incheon through the location quotient index analysis of the marine industry in the target area. A case review of the Yeongheungdo demonstration area and diagnosis of issues in the marine energy development sector with the lowest degree of specialization was conducted, to solve field problems such as overlapping problems in marine-use zones and civil complaints between stakeholders. It was concluded that it is necessary to prepare a policy decision support system based on objective and quantitative grounds.

석유 및 천연가스 생산에 사용되는 고정식 해양플랜트에는 자켓 구조물이 가장 많이 사용되고 있다. 생산에 사용되는 자켓 구조물은 풍하중이나 파랑하중에 의해 인명의 피해 없이 변위 및 응력에 대해 안전해야 한다. 그러나 1940년대 후반부터 사용되어 온 자켓 구조물은 피로하중, 노후화로 인해 내구성에 문제가 생기고 있다. 본 논문에서는 자켓 구조물의 안전성을 검토하기 위해 모드형상을 이용하여 자켓 구조물의 손상 위치를 탐색하는 방법을 제시한다. 제시한 손상탐지기법의 효용성을 입증하기 위해 자켓 구조물의 유한요소모델에 임의의 손상을 모사하였다. 유한요소모델의 손상 전 모드형상과 손상 후 모드형상의 모달 변형에너지의 변화를 이용하여 손상 지수를 유도하고 유도한 손상지수를 사용하여 손상이 있는 부재와 손상이 없는 부재를 분류하였다. 연구 결과 손상지수가 '0'인 부재를 제외한 나머지 부재 모두 본 연구에서 제시한 손상탐지기법으로 손상 부재를 판별할 수 있었다.

Despite the facts that navigation technology and educational programs were developed, and that maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. Accident prevention is emphasized because of the extreme life, property, and environmental losses that accompany maritime accidents. Even though there are a variety of preventive activities, their performance is not satisfactory. In order to promote preventive activities and to organize safety management, a Preventive Index of Ship Accident(PISA) and a Preventive Level of Ship Accident(PLSA) which are abstracted from the statistical data of ship accidents (2009~2013) are proposed. The survey module by which these variables can be calculated is composed of preventive domains such as education, engineering, enforcement and information, and is applied for the preventive indexes measurement of cargo, passenger, tanker, tugboat and fishery ships. We compared and analyzed measured result with statistical accident rates and cases to confirm the index utilities. It was found that there is some correlation between the index value and the ship accident rate. It is expected that this index will become useful to evaluate a preventive status for the prevention of ship accidents and for the maritime safety culture.
