ABSTRACT:
A technique for accurate determination is provided which allows, at any point of navigation of a tanker and regardless of variation in the velocity of the tanker, the determination of the oil content in deballasting water and tank cleaning water that has been discharged during the navigation of a range extending from said point of navigation to another point with a given distance backward of said point. The technique comprises the determination of an instantaneous rate of discharge of oil content based on the concentration of oil and the quantity of water discharged within a given period of time, thereby obtaining the quantity of oil discharged within a given distance up to the present time as well as an incremental quantity of oil discharged in the period of time that the tanker was traveling a predetermined distance, and use of the thus obtained signals of discharged quantity for recording or control of discharge of deballasting water and tank cleaning water. According to this method, the condition (4) specified by the IMCO as a standard for regulation of discharge of deballasting water and tank cleaning water from a tanker is fully satisfied, and steady navigation of the vessel is made possible. The method uses a practically simple sensoring system and process of mathematical calculations, thus obviating a sophisticated computer of the kind heretofore required.
