2119023 9306309 PCTABS00021 Arrangement for a boom for confining and collecting escaped oil or the like, having a supporting part and an adjacent shield part, in conjunction with which the supporting part consists of a collapsible hose-like casing divided into a number of sections with expansion devices so arranged as to expand the casing from the position of repose into the air-filled operating position. What is novel is the arrangement on the inside of the casing of at least one piece of material (10) in the form of a flexible, impervious woven or foil material attached to the casing, which is attached to the material of the casing with an impervious connection to it at the top and at the sides, but is free towards the bottom, which piece of material exhibits a form and an extent which permit the piece of material to produce a pocket (9) capable of being filled with air and ensuring the buoyancy of an adjacent part of the boom in a damaged and water-filled condition.
