A plurality of perforate cones are secured at longitudinally spaced intervals to an elongated cable. The lowermost cone is arranged over an underwater source of oil leakage and the upper end of the cable terminates at an oil collecting chamber adjacent the surface of the water. Leaking oil thus is reduced to small bubbles or streams by passage upward through the perforate cones which also direct the oil inward toward the cable, forming a column of oil which is collected at the collecting chamber.
