<p>PCT No. PCT/NO92/00041 Sec. 371 Date Sep. 8, 1993 Sec. 102(e) Date Sep. 8, 1993 PCT Filed Mar. 6, 1992 PCT Pub. No. WO/9215481 PCT Pub. Date Sep. 17, 1992.A method for collection of oil slicks (20) on a water surface, using a barge (1) or similar vessel, with a rectangular, transversal bow section (4) and which is towed by a towboat (5). 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 oil film (20) in front of the bow 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. Outside the bow section (4) there is fastened a device, e.g., a rotating drum (12) or nozzles (20), directed so as to have 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 slanting direction, which entrains oil from the oil film (14) across the transversal bow section (4).</p> |
