An improved boom for use in containing oil spills and the like on water comprises a flotation tube, an upper chain pocket, a skirt, and a lower chain pocket. The boom is strengthened by placing a chain, or wire rope if a stiff boom is required, in the upper chain pocket. The skirt is made to sink by placing a chain in the lower chain pocket. Both the tube, pockets, and skirt are fabricated from a plastic mesh pervious to both water and the spill. The spill is contained, and buoyancy provided for the boom, by filling the flotation tube with a particulate liquid sorbent, which preferably is a particulate polyurethane material. This boom has significant advantages when used on flowing water, as the water can pass through the boom without having to flow under it and thereby entrain some of the spill with it. A smaller pillow boom, which has no skirt or lower chain pocket, and which is of use in containing small localised spills is constructed in the same way. |
