Abstract: An apparatus for collecting oil from a surface of a water body comprising a drum, the drum rotatably mounted on a vessel such that a lower portion of the drum is positioned below a waterline of the vessel, and a wiper member on the vessel, the wiper member positioned and configured to wipe oil from the drum below the surface of the water body. Wiped oil is collected below the surface of the water body through a series of collection tanks. A dryer wiper wipes water from an unsubmerged portion of the drum to improve oil uptake.

Abstract: An oil skimming apparatus for collecting oil from a surface of a water body is provided comprising a floatable hull, a hollow non-floating cylinder rotatably mounted adjacent a bow of the hull, and an arrangement of scrapers and troughs for scraping oil from the inner and outer surfaces of the cylinder and transporting the collected oil to an oil collection tank. The cylinder has port and starboard open ends, which allow oil to collect on the inner surface of the cylinder during rotation. A pair of bulkheads are fixed inside of the cylinder. A pair of pontoons extend fore of the bow of the floatable hull. The pontoons are spaced apart to form an oil collection area. The cylinder is rotatably mounted in the oil collection area via a drive shaft-member passing through the port and starboard bulkheads.
