The discharge of noxious liquid substances or contaminated water genarated during the tank cleaning, line washing and tank ballasting from chemical tankers into the sea is regulated by the new international convention for the prevention of marine pollution. For the practical enforcement of the regulation, the accurate estimation of actual amount of residual liquid substances and the investigation on measures for minimizing the amount of residue have been required. The investigation of the line blowing which is commonly applied to the present chemical tankers after unloading for reducing the quantity of residue in the piping arrangement is reported. Experiments were performed with the laboratory test facilities using water and air as the working fluid. In accordance with the test procedures of the regulation, the test arrangement is provided to maintain a back pressure with the 10 m. long vertical riser pipe or the constant pressure valve set at 1 bar minimum at the end of the horizontal or inclined pipe. The results of observations of air and water flow and the measurements of quantity of remaining water in the horizontal or inclined pipe are described. The effects of air capacities, pipe diameters, inclination angles and method of maintaining back pressure etc. on the line blowing process were investigated experimentally. The constant pressure valves used to maintain a back pressure showed satisfactory performance.
