The discharge into the sea of tank washings of the chemical tanker shall be prohibited except when the regular conditions are satisfied. It is decided by THE INTERNATIONAL CONVENTION FOR THE PREVENTION OF POLLUTION FROM SHIPS, 1973 AS MODIFIED BY THE PROTOCOL OF 1978 RELATING THERETO (MAR-POL 73/78) and the concerned domestic law. Concerning hazard liquid substances, the effluent from the tank washing operation shall be dischanged to a reception facility at least until the concentration of the substance in the discharge has fallen to the residual concentration specified for the substance.<BR>Therefore it is necesary for the estimation of the amount of the needed water that the relation between the residual concentration and the amount of the used water is grasped. It is investigated using a model tank and the amount of the water for tank washing is estimated by the results.
