ABSTRACT:
The present invention is an oil recovery system designed to work in conjunction with a vessel. Forming a part of the system is a floating boom structure which confines oil laying at or just below the water's surface and directs the same to an independently mounted nozzle. Oil and water at the nozzle are induced into the nozzle by a vacuum. The depth and attitude of the nozzle are adjustable and the nozzle is movable up and down and side to side. Wave and weather sensors measure various parameters including water temperature, wave amplitude, wave velocity, wave direction, vessel speed, air temperature, and oil layer thickness. The sensors provide input to a computer which continuously generates a cyclic wave profile. The nozzle is automatically controlled and moved in accordance with this wave profile. In this way, the nozzle is maintained at an optimal depth for oil skimming irrespective of changing surface conditions such as wave amplitude, wave velocity, and wave direction. Resultantly, oil at the surface of the body of water is quickly and efficiently collected. Collected oil and water are separated by a series of oil-water separators stationed on the vessel.
