Much of the oil spillage in the seas occurs in connection with tank cleaning on board tankers, where the washing water together with any oil remains is continuously discharged overboard by water-driven ejectors. When the 1973 Inter-Governmental Maritime Consultative Organization set limits on the maximum permitted oil discharge from ships, it became imperative not only that this slop be cleaned, but also that the quantity of dirty water to be treated be greatly reduced. The "JMW Slop Shrinker" is a water turbine-driven centrifugal pump which replaces the water-driven ejectors. This system has the advantage of using less water than an ejector and, since the driving water is kept separate from the dirty slop water, it can be conducted back to the wash water circuit, or discharged overboard without the need for cleaning. This means a considerably reduced quantity of dirty slop water to be treated in the slop tank system.
