ABSTRACT:
A dual drum skimmer is provided for the removal and recovery of oil floating on water. The skimmer includes two oil pick-up drums arranged along a common axis which pick up oil and deposit it in a collection trough. Oil deposited in the collection trough is directed to a reservoir trough arranged on the opposite side of the drums from the collection trough. The drums are formed as hollow, closed cylinders and, together with the reservoir trough, provide the total buoyancy necessary to float the skimmer. The skimmer is particularly effective in shallow and in trash laden water and can operate in water depths of as little as three inches.
