FIELD: gathering oil spilled on water surface.
SUBSTANCE: oil is gathered from water surface by means of bucket together with water. Then water and oil are separated into lower and upper parts respectively due to difference in specific gravities. Water from lower part of bucket is drained through holes made in plate. Diameter and length of holes provide for dripping of oil from upper part of bucket by gravity. After draining of water, oil is drained to special reservoir. This procedure is repeated several times.
EFFECT: enhanced efficiency; low cost.
