ABSTRACT:
An oil spill recovery system deposits a polypropylene quilt onto an oil spill on water, the quilt being deposited at the speed of movement of a water craft so there is no relative motion between the quilt and the water. The quilt is allowed to rest for a given dwell time, then picked up at a speed to prevent relative motion between the quilt and the water. The quilt is retrieved and placed into a first scray. Squeeze rolls remove the quilt from the first scray and squeeze oil therefrom. A plurality of scrays and squeeze rolls may be used. A sewing machine or heat sealing apparatus may be disposed between two scrays so the quilt can be spliced as necessary during operation of the system.
