A method for collection of oil slicks (20) on a water surface, using a barge (1) or similar, with a rectangular, transversal bow section (4) and which is towed by a towboat (5) and where there is at least one collection device (8) designed to lead oil in toward the bow section (4) of the barge (1). The water below the ail film (20) in front of the baw section (4) of the barge (1) is set in an upward flow, so that water is led up. from the water surface, entraining the oil film (20) and across the forward, transversal bow edge (4) and into a tank room (3) in the barge (1). The water in the lower portion of the tank room (3) is led or flows freely into the surrounding water. A device for embodiment of the method comprises a barge (1) or similar; designed to be towed across the water. The barge has a rectangular transversal bow section (4) and there is mounted at least one long collection device (8) in the form of an oil boom. Outside the bow section (4) there is fastened a device, e.g. a rotating drum (12) or nozzles (20), directed in an upward slant, designed to produce an upward flow of the surrounding water immediately in front of the transversal bow section; sufficiently strong to accelerate the water in an upward scanting direction, which entrains oil from the oil film (14) across the transversal bow section (4).
