At the adjacent sea area of Busan Central Wharf, a variety of vessels, such as middle-large passenger ships, small fast sailing ships, container ships, cargo ships and working ships as well as small miscellaneous vessels are freely sailing comparatively without special steering and sailing Rules and marine traffic control because exclusive wharfs in accord with their purpose and use have been arranged in each wharf. In this research, we analyzed traffic stream and navigational characteristics of main traffic route based on statistics and distribution of tracks by ship's type and tonnage of the passing vessels after conducting marine traffic survey twice using exclusive software by targeting the sea area during the period of time. We examined the traffic safety of the passing vessels by classifying the sea area by each function based on the analysis about this traffic situation, and analyzing the effect by designating 'Buknea passage'. We also studied the plan for the effective rearrangement of Central Wharf considering basically the traffic safety oif arrival and departure in a point if view of navigators.

물동량 증가로 인하여 부산신항에는 극초대형 컨테이너 선박들이 입항하고 있으며 서컨테이너 부두 건설 사업이 완료되면 부산신항 진출입 항로 내 다양한 조우 상황 발생으로 충돌 위험 상황을 초래할 수 있어 선박 통항 안전성 향상 방안 마련을 위하여 부산신항 내 항만 입출항 현황과 해상교통흐름을 살펴보았으며, AHP 기법을 활용하여 위험요소 및 안전대책 식별로 도출된 안전대책을 기반으로 환경 스트레스 모델을 활용하여 해상교통류 시뮬레이션을 실시하여 각 안전대책의 교통 위험도를 파악하였다. 설문조사 및 시나리오 평가 결과, 선박운항자는 일방통행을 위한 진입금지 해역 설정을 가장 중요하게 생각하였으며, 이는 위험도 경감에 큰 효과가 있을 것으로 예상되었다, 본 연구는 부산신항을 입출항 하는 선박들의 통항 안전성 제고를 위한 안전대책 마련의 기반이 될 수 있을 것이다.

Recently, installation projects of structures such as offshore wind farms have been increasing, and the installation of such marine obstacles could affect ships that pass nearby. Therefore, the purpose of this study was to quantitatively evaluate the risk posed to passing ships due to obstacles in their passage. Hence, parameters that affected the risk were selected, and scenarios were set based on the parameters. The scenarios were evaluated through the ES model, which is a risk assessment model, and we confirmed that the risk ratio increased as the size of the obstacle increased, the safe distance from the obstacle increased, the speed of ship decreased, and the traffic volume increased. Additionally, we found that when the traffic flow direction was designated, the risk ratio was lower than that of general traffic flow. In this study, we proposed a generalization model based on the results of the performed scenarios, applied it to the Dadaepo offshore wind farm, and demonstrated that the estimation of the approximate risk ratio was possible through the generalization model. Finally, we judged that the generalization model proposed in this study could be used as a preliminary reference for the installation of marine obstacles.

In adjacent sea areas of Yeosu, there are many crossing traffics between eastbound and westbound vessels. Traffic congestion is increasing in sea area of east Sori island and near Yokji Island. In this research, we established TSS near Yeokmando Areas and new recommended route which connected to Seopdo west recommended route to reduce meeting traffic between eastbound vessels and westbound vessels.

Recently, bridge design and／or construction works on marine traffic route are undertaking in Korean waters. Naturally the ship-handling difficulty and hazardous to navigation should be increased when the bridge is constructed on the shipping route. Unfortunately, however, it is impossible or not desirable to secure wide enough bridge span width due to geographical condition or economic point of view. Therefore this study aims to propose the consideration factors during the bridge design process, and the traffic volume control, speed limit and other alternative measures to secure traffic safety using marine traffic flow simulation technique.

근래에 해상물동량의 증가로 선박에 의한 해상운송이 늘어나면서 우리나라 연안뿐만 아니라 전 세계 해상의 교통흐름을 복잡하게 만들었다. 특히, 주요 항만 인접해안, 협수로 및 주요 통항로는 더욱 복잡한 교통흐름을 보여주고 있다. 이에 어느때 보다 선박에 의한 해양사고 발생 가능성이 높아졌다. 이 연구에서는 해양사고가 생길 가능성이 가장 높은 해역에서의 원활한 교통흐름과 안전운항을 위해 우리나라 뿐만 아니라 전 세계적으로 설치 운용중인 VTS 시스템에 대해 고찰 하였다.

From the viewpoint of navigation safety, it would be best if it's possible to build a bridge whose main span is wide enough, however, sometimes it may not be possible due to geographical or economic reason To construct the bridge on the shipping route, consideration factors for marine traffic safety must be investigated and examined from the viewpoint of marine traffic engineering. This study aims to secure marine traffic safety and maintain smoothly traffic flow through assessment qf these factors. As the first step, examination factors such as traffic volume, ship size and bridge width were assessed quantitatively using marine traffic flow simulation technique.
