MODEL STUDY OF THE DILUTION OF SOLUBLE LIQUIDS DISCHARGED FROM TANKERS

A program of model experimental research was undertaken to study the dispersion of effluent discharged from chemical tankers. The effects of discharge location, volume rate and velocity of discharge were investigated as well as the effects of ship speed and propeller action. The experimental study consisted of tests in a circulating water channel as well as tests in a towing tank. The tests in the water channel included measurements of the dilution of a released tracer for the following conditions: (1) an unobstructed flow in the channel, (2) a propeller operating in the channel, (3) a foreshortened model of a typical chemical tanker fixed in the water channel without a propeller, and (4) the same model but with an operating propeller. The tests in the towing tank included measurements of the dilution of a tracer released from a geometrically scaled, eight ft. long tanker model operating with and without a propeller. This work was undertaken to provide guidance to the U. S. Coast Guard in regard to minimizing the environmental impact of washwater discharged during tank cleaning operations. (Author)
