ABSTRACT:
A skimmer-boom apparatus for skimming and diverting floating pollutants, such as oil, from the surface of water experiencing high current velocity comprising an upstream and a downstream buoyant member connected by an impermeable membrane. The buoyant members are coupled at one end and open at the other, resulting in a "V" shaped structure. The upstream member is disposed to skim oil or other floating pollutants between it and the upstream edge of the membrane. The cross-sectional area of the skimmer-boom as defined by the membrane and the buoyant members increases in the direction of the open end of the "V" in order to maintain constant mean flow velocity of the skimmed water and pollutant contained within the apparatus as it flows towards a collection area from the narrow, closed end to the open end of the structure. Oil thereby collected may be skimmed or otherwise removed from the capture area.
