Priahna oil skimmers, designed by Skandvik, were originally intended for picking up oil in harbors. One such vessel, the Petrolina, was employed to pick up oil in open waters after the Russian tanker Tsesis ran aground south of Stockholm, Sweden. The Petrolina picked up 4 T of oil in 7 min-a rate of 34 TPH. Though the vessel collected only about 60 T of oil during the first day due to lack of barges to receive the oil, it probably could have collected greater than 250 T. The vessel is designed so that perforated steel belts 1.6 m wide are lowered into the water between the pontoons of the catamaran hull. Heavy oil adheres to the steel belts, while water and light oil escape through the perforations. Light oil is captured further astern using smooth steel belts moving vertically. The oil collected is almost entirely free from water.
