ABSTRACT:
An oil spill retrieval vessel has an influent for collecting oil and seawater that forms an oil spill or slick. The vessel has an interior that contains the skimmed oil and water and separates the oil within the vessel and underwater. A plurality of separator surfaces inside the vessel and below water surface are vertically stacked to catch and accumulate oil as it rises within the vessel interior. An influent flow line has oil outlets along a portion under the separator for preliminarily accumulating oil droplets on louvers that angle away from each outlet on the influent flow line. A transverse baffle plate above the separators has openings with angled plate-like members or louvers thereon for further accumulating and concentrating the oil that leaves the separator. In this fashion, a three-stage oil accumulation and oil-water separation system is provided that includes: 1) the influent flow line; 2) the separator with its vertically spaced plates; and 3) the transverse baffle plate and its louvered openings.
