Abstract
An oil catching boom which comprises, on the one hand, an upper part in the form of a floating, flexible hose and, on the other hand, a skirt (3) attached under it and extending into the water. With the purpose of providing a boom the flexibility of which is easy to adjust according to intended use, the upper part is made up, on the one hand, of an outer hose (1) of a fabric-like material, open at its ends, and, on the other hand, of an inflatable inner hose (8) placed inside it. The flexibility of the inner hose or its division into segments is achieved by means of hose strictures which are produced, for example, by means of band-like throttling rings (11) fitted at predetermined intervals around the hose. A longer unit assembled from boom parts can be equipped with an inflation hose extending over its hole length.
