Abstract
A simple barrier of the type having a series of buoyant tubular sections interconnected by a central cable and provided with a depending skirt. A portion of the skirt that is not attached at the joints is adapted to form an upwardly directed channel which effectively prevents the passage of pollutants through the openings at the joints without the necessity of directly sealing the openings.
Claims5
A barrier for confining floating pollutants comprising:
- a plurality of buoyant tubular boom sections serially interconnected by a cable passing longitudinally therethrough;
- a flexible skirt, having an upper edge portion and lower edge portion, means attaching the upper edge portion of the skirt to a lower portion of the boom sections except for a portion at the joints to define a non-attached edge portion between adjacent boom sections;
- a lower cable member attached to the lower edge portion of the skirt;
- said non-attached edge portion of the skirt comprising a portion that is elastic or has a length greater than the distance between corresponding points of the boom sections for forming an upwardly oriented channel, operative, with water passing between the boom sections and non-attached portion of the skirt, to channel water upwardly from below the surface, restricting the passage of floating pollutants.
