Abstract: A boom (1A) is described, especially for containing oil spills and/or other similar pollution at sea, in rivers or on water surfaces, comprising an elongate body consisting of an element having positive buoyancy relative to the surrounding medium, so that a freeboard (5) is provided, and a hanging skirt (6), which boom (1A) is of the type that is usually lowed behind towing vessels or is moored (2) so that the boom (1A) basically forms a U-shape having side arms (4) that define a front opening (10) between them, which arms extend from a rear area or apex (7) when the towing vessels or mooring (2) pulls at the free ends of the arms of the boom (1A) in order to tow the boom (1A), and wherein the skirt (6) is provided with a draught that varies from a minimum size or depth in the area at the boom apex (7) to a maximum size or depth at the free towing ends (15) of the side arms (4) of the boom (1A).

Abstract: An apparatus or system for containing oil and the like floating on the surface of a body of water, comprising a relatively elongate channel defined by two side-defining faces that diverge from one another from a narrow inner end to a wider opening, the channel being movable such as by towing with the aid of one or more vessels, which apparatus is made of non-rigid materials. The apparatus comprises a tapered channel portion between the two side-defining faces, a wedge-shaped structure and a collecting means or separator, wherein the tapered channel portion, the wedge-shaped structure and the separator are arranged one after the other as interconnected or integrated units, thereby forming a continuous “hull” having freeboard, and longitudinal towing devices are provided that are fastened to said units, the said towing devices and thus the towing forces intersecting in an area at the rear end of said wedge-shaped structure seen in the towing direction.
