The applicability of the method to predict an amount of oil outflow from a bottom ruptured ship tank of double hull at the bottom basing on hydraulic balance of inside and outside of the tank is investigated for three kinds of test oil in addition to the experimental conditions of tank sizes, tank configurations and conditions of cargo loading. The amount of oil outflow has been measured by using VLCC 1/50 scale model tank with double hull under the following conditions : oil densities=810〜900 Kg/m^3(15℃), dynamic oil viscosities=3.1〜100 cSt(15℃), double bottom heights=double side widths=0.02m, 0.04m, 0.06m, oil tank cross sectional areas=0.26〜0.52m^2, initial oil levels=0.2〜0.5m, drafts=0.2〜0.45m and simulated circular puncture size=71mmφ. The predicted amount of oil outflow is compared with the experimental data. Good agreement is shown.
