イスタンブール海峡における海上交通の安全管理 : 狭水域部における行き会いの管理基準

Abstract

According to recent statistics, there has been a steady increasing in the number of large-size of ships that pass through the Strait of Istanbul, which is the important international waterway links to the Black Sea and the Mediterranean Sea. The new VTS (Vessel Traffic System) is constructed for safety navigation in the strait as an important safety measure but regulation criteria has been a matter of discussion at the traffic scheme regulation for the Strait of Istanbul. However the current navigation system also have not improved enough to provide to the safety navigation. For an effective VTS, it is necessary to suggest the navigable criteria with the large-size ships encountering each other. For this purpose, the marine traffic simulation has been employed to determine the encountering probabilities for large-size ships that pass through the confined water areas of the strait. This paper provides the allowable criteria for encountering of large-size ships based on the results of a simulation study by application of environmental stress model. It is expected that this management criterion will effect to maximize the value of the new traffic system in the strait.
