Abstract: The apparatus comprises a turntable plate arranged on a platform (1), there being tube means (6) mounted on the plate such as to form a conical shape with the aid of a bolted joint (7). To one side of the turntable plate (3) there are arranged on the platform three rollers (12,13,14) and on another part thereof there is arranged a feed roller (29) and guide rolls (31,32). The roller (29) and guide rolls (31,32) are adjustable in two planes in relation to the platform (1). For winding up a boom it is taken between the rolls (31,32) over the feed roller (29) and over the rollers (12,13,14), where the expansion means are flattened so that the boom is wound up in a flattened condition on the tube means (6) forming the conically shaped winding bobin.

Abstract: The present invention concerns an arrangement for collecting of oil (11) and other contaminations floating on a water surface. The arrangement includes a container-like structure (7) floating on the water and provided with a closable inlet (15) for water and oil and located at the water surface level. In the bottom of the container-like structure (7) there is provided downwardly projecting tubes (16-18) ending into the water and provided with pump means (19-21) for pumping water in and out. At the upper portion of said structure (7) there is connected an outlet pipe (8) for oil. When pumping out water, oil is collected in the container space and at a subsequent pumping in of water the oil is pressed out through said outlet pipe (8), the inlet opening (15) being closed at that occasion.
