Abstract

An oil recovery device having a downwardly and rearwardly traveling oil absorbing belt, to pick up oil on a body of water. The belt travels around an upwardly and forwardly positioned drum to be engaged by a porous squeeze belt to remove the oil from the oil absorbing belt. Rearwardly of the belt is an oil collecting enclosure to collect oil not recovered by the oil absorbing belt. The device has a downwardly and rearwardly inclined bow ramp over which an oil/water liquid passes into a through passage in the device, and water having oil separated therefrom passes out longitudinally spaced bottom openings, with the flow through these openings being controlled by closure doors.
