    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.

    Abstract: PURPOSE:To eliminate the need for operators and to make constitution simple by controlling a solvent supply pump of an oil content meter with the navigation speed signal detected with the ship speedometer of a tanker and obtaining the discharge rate of oil per unit distance from the output of the oil content meter. CONSTITUTION:The sampling pump 14 of an oil content meter 11 is controlled by the ballast displacement water flow rate signal Q detected speed with a flowmeter 12 and a solvent supply pump 15 by the navigation speed signal V detected with a ship speedometer 13. More specifically, the pumps 14, 15 are so controlled as to have the relations q1 Q, q2 V where the sampling rate of the pump 14 is defined as q1, and the solvent supply rate of the pump 15 as q2. The sample drawn with the pump 14 is ballast displacement water, and for example, carbon tetrachloride is used for the solvent supplied from the pump 15. An extractor 16 mixing and extracting the ballast displacement water and the solvent, a separator 17, an IR analyzer 18 and an integrator 19 are provided.
