ABSTRACT:
A device for recovering oil floating on the surface of water comprising a framework (50) and a number of discs (51) rotatably mounted thereon. The framework is supported on floats (58,59) with the discs partly immersed in the water, and each disc is associated with a scraper (57) and chute (54) so that oil removed from the disc is deposited into a collection tray (52) from which it can be removed via line (53). Each disc (51) carries at least one axially directed concentric ring (4,5) which presents an inwardly directed surface (7,8). Each disc may carry a plurality of rings of the same or different axial depths.
