Popis: A compact oil spill recovery system made up of a special oil suction float, an eductor-driven hydraulic fluid conveying unit, an oil/water separating unit, etc., was devised to the basic design concept of the previously-developed Mitsubishi hydraulic tanker desludging system and installed in a small, self-propelled, twin-hull craft. A 9.60 m long, 4.10 m wide, and 1.40 m deep experimental oil spill recovery ship completed in this manner successfully cleaned up a slick of heavy oil, 7 m × 30 m in area and 0.7 – 2.0 mm in film thickness, in less than three minutes at 0.5 – 1.0 kt and proved very stable, steerable, and easy to operate. Oil content of water at the outlet of the oil/water separating unit was less than 1 ppm. A range of oil spill recovery ships have since been designed, fully weighing opinions of potential customers as regards such items as economy of operation, and capacity.
