ABSTRACT:
An arrangement for a boom for confining and collecting escaped oil, or the like, having a tubular casing and a shield part attached thereto. A plurality of spaced dividing walls are disposed within the tubular casing. The tubular casing is movable between a collapsed rest position and an expanded operational position. Expansion devices are attached to the tubular casing and are movable between a folded position and an unfolded position. Biasing members are attached to the expansion devices for urging the expansion devices into the unfolded position so that the tubular casing is moved into the expanded position. A valve is operatively attached to the tubular casing so that air may flow into the tubular casing through the valve when the tubular casing is expanded. An impervious flexible sheet material has a mid-portion and opposite side edges sealingly attached to one another so that the bottom end portions form an opening. A first chamber is defined by the sheet material and the chamber is open downwardly so that air may fill the chamber when the tubular casing is in the expanded position to provide buoyancy of the boom even when the boom is damaged.
