Abstract
A floating waste oil skimming device comprising a pair of hulls between which is suspended a skimmer box containing a plurality of oleophilic discs. The skimmer box has an outwardly opening bottom door which promotes a draft of water through the skimmer box when the device is in forward motion. Alternately the device can be operated in a stationary mode wherein water is evacuated from the skimmer box by means of a stand pipe inside the box. The skimmer box and oleophilic disc array are demountable and the pair of hulls can be folded together for transportation.
