A device (1) and a method for separation of floating sludge oil from water in a storage tank (2) for petrochemical waste products, typically onboard a ship or in a land based facility with a similar function. The device (1) comprises a flotation body (3) which together with a receiving vessel (4) for the sludge oil mounted adjacent to the flotation body (3) is slidably attached along a guide rod (5) extending in the height direction of the storage tank (2). An evacuation conduit (6) for the sludge oil is positioned adjacent to a bottom portion (7) of the receiving vessel (4). The device (1) is particularly characterized in: that the flotation body (3) and the receiving vessel (4) are attached to a common slide sleeve (8), said slide sleeve being non-rotationally mounted relative to the guide rod (5) by means of rotation locking means (9); and that the evacuation conduit (6) includes a flexible suction hose (10) coupled to a suction pump (11) arranged for sucking up the sludge oil, said suction pump (11) being positioned outside of the storage tank (2). |
