ABSTRACT:
A system for recovering oil from an oil spill site. A vessel transports buoyant, oil absorbent material to the spill site. The absorbent material is dispersed below the water surface and advances upward toward the water surface, thereby absorbing oil and water. The dispersed absorbent material is contained and transferred back to the vessel. Oil and water are removed from the absorbent material on the vessel, and the absorbent material may be reused.
