The Salwico oil pollution monitor has now been successfully tested against the USCG test specification for the full range of ballast applications, i.e., crude oils and black and white products. It has already been tested against the test specification contained in IMCO Resolution A. 393 (X) and has received the corresponding certificate of type test from the administrator in Greece, Norway, Sweden, the UK, and the USSR. The monitor has been sold to 150 ships. The principle employed in the monitoring is characterized by 3 steps-filtering out oil from sample water in a lipophilic tape; scanning the type for discoloration; and gas evaporation. The use of 2 different parameters in the oil (color volatility) makes it suitable for monitoring the full range of hydrocarbons from gasoline to Bunker C and all kinds of crude. The filtering principle also makes the monitor les sensitive to contaminants and air bubbles normally present in the sample water than other techniques. The monitor is delivered as an instrument recording oil content in ppm, or complete with a computing unit, presenting amount of discharge oil in liters per nautical mile and in total quantity.
