  • Patent number: 4006082
    Abstract: A process for the collection of lighter than water pollutant spills to a small boat contained emergency collection sump is disclosed. A floating sump is disposed onto the surface of the water near a spill for the collection of pollutants at a surface disposed lip on the sump. A floating and flexible boom, dead ended to one side of the sump lip, is disposed from the sump to surround the spill. The boom is threaded through vertical take up rollers and then dead ended to the side of the small boat used for the control of the spill. Upon collection of the floating boom at the vertical take up rollers, collection and confinement of pollutants to two confined areas occurs. With regard to the spill as initially surrounded, the boom, when collected, defines a first decreasing area forcing the collection of the surface disposed pollutants to the sump lip.
