PROBLEM TO BE SOLVED: To shorten a time necessary for a sink of a part of a float-and-sink type oil fence, and to enable the quick emergency evacuation of a tanker.SOLUTION: An oil fence device 3 connects a plurality of float-and-sink type oil fences 1 to one another, and surrounds anchoring equipment 101 in a harbor and a tanker T which is anchored to the anchoring equipment 101. In the oil fences 1, a float 7 is integrally arranged at a band-shaped body 6 along a fence longitudinal direction, and a large number of weights 8 are arranged at a lower part of the band-shaped body 6 along the fence longitudinal direction at intervals. A tanker emergency evacuation part M is arranged at a portion corresponding to a stem of the anchored tanker T at a part of the oil fences 1 in the fence longitudinal direction. In the tanker emergency evacuation part M, the weights 8 are arranged at both sides or one side of a second air feed-discharge connecting part 10C so that weight per unit length becomes larger than that at the other portion.SELECTED DRAWING: Figure 1

    【課題】浮沈式オイルフェンスの一部の沈下に要する時間を短縮し、速やかなタンカーの緊急避難を実現する。【解決手段】オイルフェンス装置3は、複数の浮沈式のオイルフェンス1を接続して、港湾内の係留設備101と、この係留設備101に係留されたタンカーTとを取り囲む。オイルフェンス1は、帯状体6にフロート7がフェンス長手方向に沿って一体に設けられ、帯状体6の下部には前記フェンス長手方向に沿って多数のウエイト8が間隔をあけて設けられている。オイルフェンス1の、前記フェンス長手方向の一部にタンカー緊急避難部Mを、係留されているタンカーTの船首に対応する部分に備える。タンカー緊急避難部Mは、第2給排気接続部10Cの両側または一側に、他の部分よりも、単位長さ当たりの重量が大きくなるようにウエイト8が配置されている。【選択図】 図1
