ABSTRACT:
An oil collecting vessel for removing oil from the surface of water, comprising at least two oil booms arranged in front of the vessel in V-shape, the oil booms comprising buoyant screwlike draw booms arranged to rotate so as to draw surface water and oil into a receiver provided in the vessel, simultaneously displacing the vessel forward. The oil booms further comprise boundary booms provided in parallel with the draw booms so as to lead the surface water displaced by the draw booms into the receiver in the vessel; whereby each oil boom comprises a number of draw booms connected in series by means of universal joints, the draw flanges of the outermost draw booms being larger than those of the other draw booms, so that the vessel is steerable and the opening direction of the oil booms adjustable by operating the outermost draw boom of one of the oil booms at a speed different from that of the outermost draw boom of the other oil boom.
