Recent results of development and testing of the free-vortex approach to floating oil recovery are presented. This work has been directed toward high-seas oil-spill recovery-a much-needed capability in offshore oil operations. The freevortex technique, in contrast to typical skimming methods, is not sensitive to surface disturbance and provides for capturing oil at a distance from the skimmer. Free-vortex skimming operates through induced flow fields-a surface inflow that gathers oil and a central vortex that concentrates the oil for removal by conventional pumping. The principles and hardware for maintaining the free-vortex flows on an open surface are described. Testing was conducted with different oil types, oil films 1 in. thick or less, in calm water and waves. A good capability for operation in high-seas conditions is indicated.
