There is disclosed in the present application, a floating skimming barrier assembly for confining oil and removing it from the surface of water. The assembly comprises an elongated flexible sheet supported in a generally vertical position in the water by a plurality of spaced-apart flotation units. The collection of floating oil, which takes place only at certain locations along the length of the barrier is accomplished by skimming panel sub-assemblies attached to the barrier sheet. Each sub-assembly includes an inflated float, a frame upon which there is mounted a tank having a large inlet opening on its inner surface and an outlet conduit connected to the bottom of the tank and leading to a discharge end adapted to being connected to a flexible hose at the surface of the water. The barrier assembly including skimming sub-assemblies and other flotation units at regular intervals is compactly foldable for shipment in a packing case.
A skimming sub-assembly for collecting oil floating on water by the motion of a barrier in a forward direction, comprising a two part rigid frame mountable upon an elongated flexible barrier sheet adapted to being supported in a generally upright position and partially submerged in the water, a tank integral with the frame and extending from a level above the water to a bottom substantially below the water level, the tank having an inlet opening near the water level and a conduit extending between the bottom of the tank and an outlet connectible to a suction hose at the water surface.
A floating skimming barrier assembly for collecting oil floating on water by the motion of the barrier in a forward direction comprising an elongated flexible sheet, a plurality of flotation units located at spaced-apart intervals along the length of the sheet each including an inflatable float connected to the sheet for maintaining it in generally upright position and partially submerged in the water, the sheet when so disposed in use having inner and outer surfaces, and a skimming sub-assembly comprising a two part frame including members on the inner and outer surfaces of the sheet, a tank integral with the frame and having an inlet opening at the inner surface of the sheet above the water level, a bottom below the water level and an outlet from the tank located at the surface of the water.
