大阪湾における避泊船舶の分布(日本航海学会第45回講演会)

抄録

The distribution of the ships anchored against the typhoon in Osaka Bay from 1967 to 1970 is investigated. The types of distribution is divided into two types. When large and strong typhoon looks like to attacks at Osaka Bay, the ships at anchor distribute uniformly, but they distribute rather crowded in the north prat of Osaka Bay when the typhoon is small or the course is far away from Osaka Bay. The distribution of the distance between two ships is also investigated. The number of the ships at anchor against a typhoon increased year by year. In a few years, we will hardly be able to find the surplus of anchorage in Osaka Bay.
