  • Daesan Harbor is developing under the Industrial Complex or Petrochemistry Development Plan making the port the main hub-port in the West coast. Because of this development. the traffic volume is expected to increase to 9,1.95 incoming vessels by 2020, an increase of 167% compared to 2008 figure. This study thoroughly analyzes and evaluates a systematic and comprehensive use of the fairway in the Daesan Harbor. It establishes a future oriented and safe marine transportation environment upon appropriate examination of the total fairways and sailing assistance facilities.

  • Recently, many ships such as VLCCs, dangerous cargo ships, high speed ferry boats are visiting Yeosu, Gwangyang harbor. The traffic volume of the year 2003 has increased as many as 2.5 times of 1988. However there is no suitable ships' routeing system which takes account of today's traffic situations in this area This study aims at the settling of hazardous factors to mitigate the danger to vessels in Yeosu${\cdot}$Gwangyang bay and to secure the safety of maritime environment.

  • 최근 들어서 우리나라는 각종 육해상 건축물 축조에 필요한 모래골재의 육상공급이 한계에 다다르면서 부족한 골재를 인근해역의 해저에서 채취하여 공급하고 있으며, 이에 따른 해저 골재채취 작업수역을 통항하는 선박들의 안전문제가 크게 대두되고 있다. 이와 관련하여 최근에 태안해역의 흑도/가대암 TSS 부근수역에서의 바다골재 채취를 위한 해상교통안전진단 사업을 수행한 내용을 중심으로 주변수역으로 통항하는 선박들의 통항안전성에 대하여 평가한다.

  • Marine traffic management could be defined as the implementation of managerial technical measures to improve vessel traffic safety. The managerial elements of vessel traffic management for ports and harbours or narrow channels include the total amount of traffic control, the vessel traffic separation scheme, speed restriction, traffic control by signals, the navigation information service and so forth. This research aims to quantify how much the traffic separation schemes(TSS) contribute to the alleviation effect of ship handling difficulty and to propose a design standard when the individual management measure is applied in an actual waterway. Traffic separation schemes have now been established in most of the major routes and congested waters of the world, and the number of collisions and groundings have often been dramatically reduced. In this part, the relationship between the alleviation of ship handling difficulty and the reduction of encounter figures among ships is quantitatively clarified by applying the ES model. As results of simulation analysis, it is recognized that a traffic separation system is most effective in the case of narrow width and heavy traffic volume. The centre buoy installation reduces about 1/4 of the alleviation of ship handling difficulty, TSS establishment 1/3, and design change to one-way traffic from two-way traffic reduces 1/2.

  • A mariner feels the shiphandling difficulty when the vessel onboard passes through breakwater. Until now, the shiphandling difficulty of the mariner has not been taken into account in the layout of a pair of breakwater. This paper reproduced such a situation that shiphandling is difficult enough by using marine traffic flow simulation, it is assessed by using ES Model which is a quantitative model for evaluating the difficulty of shiphandling arising from maneuvering a ship in the restricted or congested waters. The results are as follows. (1) The change in the layout of a pair of breakwaters has little influence on the shiphandling difficulty. (2) If the width between breakwaters is the same. the speed of a ship affects the shiphandling difficulty. (3) The increase of the width decreases the shiphandling difficulty.

  • A mariner feels the ship-handling difficulty when the vessel onboard passes through breakwater. Until now, there is no a layout design of breakwater to take into account the ship-handling difficulty for the mariner. 11Us paper reproduced this situation which ship-handling is difficult by using marine traffic flow simulation, and it applied to Environmental Stress Model as the assessment model which is a quantitative model for evaluating the difficulty of ship-handling arising from restriction in maneuvering water areas and arising from traffic congestion The results are as follows. (1) The layout change of breakwater has little influence for reduction of ship-handling difficulty in the areas of vessel traffic volume. (2) In the situation of same breakwater width, difference of ship speed has an effect on decrease of ship-handling difficulty. (3) Expansion of breakwater width decreases ship-handling difficulty quantitatively.

  • In the present maritime traffic conditions of Gwangyang harbor, there exists many hazardous factors which may lead to huge accidents including marine oil pollution. To mitigate the danger to vessels in Gwangyang harbor and to secure the safety of maritime environment, we established one way traffic between No.3 Route and No.4 Route, Designed of deep water line on No.3 route, Extended one-way route for Myo-Do Passage etc.

  • 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.

  • Korea has very strong shipbuilding industry in the world, so many new ships are constructed in Korean shipyards. These built vessels are carrying out sea trial at sea before delivering to shipowner, and sea trial ships cause navigation risk to other passing vessels to accomplish sea trial tests as quick turning, zigzag maneuvering and crash astern etc. in traffic congestion conditions. It occurred more than 1 collision accident related sea trial for recent 5 years. It has been increased about 30% of risk because of navigation of sea trial vessel by marine traffic flow simulation. This paper analyzed marine traffic density surveyed by AIS data for 7 days, and investigated position of marine accidents for 5 years in Korean coastal waterway, it established the sea trial prohibition areas as 10/100 level of total marine traffic volume, which is considered no danger for ship operator. This analyzed maritime safety law for setting of the prohibition waters to propose the basic legal system. It makes contribution to marine pollution prevention by setting of the sea trial prohibition water to improve the ship's navigation safety.
