  • Petroleum containment barrier for recovering floating petroleum
    Patent number: 5085538
    Abstract: The present invention relates to a continuous containment barrier comprising a plurality of compartmentalized inflatable chambers having, attached to the bottom thereof, an impermeable keel which stabilizes the containment barrier and assists in containment of the spilled petroleum product even under turbulent conditions. Extending below the keel is an elongate skirt which has a plurality of apertures therein that provide the necessary water pressure relief while still maintaining the necessary strength for successful containment of a spilled petroleum product. The barrier is designed to develop a desired height of petroleum product floating on an aqueous environment so that efficient recovery can occur.

  • Method and apparatus for recovering floating petroleum
    Patent number: 5056958
    Abstract: A method and apparatus of recovering a petroleum product floating on water comprising an elongate containment barrier, having keel means, being positioned completely around the floating product to be recovered, the area encompassed by the containment barrier being gradually reduced to develop a desired head of floating product within the containment barrier and a portion of the developed head of floating product being gradually recovered while the area encompassed by the containment barrier being continually controlled so that the desired head of floating product is maintained.
