PCT No. PCT/FI88/00169 Sec. 371 Date Jun. 7, 1990 Sec. 102(e) Date Jun. 7, 1990 PCT Filed Oct. 14, 1988 PCT Pub. No. WO89/03457 PCT Pub. Date Apr. 20, 1989.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.
