Abstract: A method and apparatus for recovery of oil from a marine oil slick. The apparatus includes a dredge (10) equipped with a suction pump (11) and a suction pipe (13) having a suction collector box (17,60) mounted on the distal end thereof for pivotal movement with respect to said pipe. The dredge is positioned adjacent the oil slick with the collector box in the current path by means of the anchor lines (32a,33a). Drive controls, which may include an automatic positioning system (75), are provided to maintain the lip (20) of the opening at a selected level of submergence along a plurality of incremental lengths of said lip comprising substantially its entire length to accommodate wave action incident from any direction. A plurality of oil/water separation devices (44) mounted on barges (45) or other convenient platforms connect with the pump outlet to receive the mixture of oil and water suctioned through the collector box and to separate the oil and water for collection.
