    Abstract

    Recent developments in effectiveness testing of dispersants are discussed, with emphasis on the Mackay-Nadeau-Steelman laboratory test. A novel flume test system is described in which an attempt is made in the laboratory to simulate a sea test involving continuous application by boat. Some recent findings of test programs are discussed and a detailed mechanism proposed for the dispersion process. It is proposed that a mathematical model be sought to express effectiveness as a function of the volumes of oil, water, and dispersant, oil viscosity, water salinity, and application method. It is suggested that this model could form the basis of a procedure for correlating effectiveness and linking laboratory tests to application conditions at sea.
