To provide a liquid level calculation method of an in-tank liquid cargo of a ship capable of accurately calculating the liquid level of the liquid cargo loaded in a tank mounted in a hull, in consideration of the influence of the deflection of the hull.SOLUTION: A curve (y) regressing to draft points (A), (B), and (C) of a hull 1 is determined, the gradients of tangential lines (t1) and (t2) of the curve (y) at the center parts in the longitudinal direction of tanks 2a and 2b are determined, a trim correction value corresponding to the inclinations of the tanks 2a and 2b is determined using the gradients as the inclinations of the tanks 2a and 2b, and the liquid levels of the tanks 2a and 2b measured by a level gauges disposed in the tanks 2a and 2b are modified using the trim correction value.SELECTED DRAWING: Figure 1

    【課題】船体に搭載されたタンク内に積載されている液体貨物の液面レベルを、船体の撓みの影響を考慮して、正確に算出することができる、船舶のタンク内液体貨物の液面レベル算出方法を提供する。【解決手段】船体1の喫水点(A)、(B)、(C)に回帰する曲線(y)を求め、タンク2a、2bの前後方向中央部における曲線(y)の接線(t1)、(t2)の傾きを求め、前記傾きをタンク2a、2bの傾斜として、タンク2a、2bの前記傾斜に応じたトリム修正値を求め、前記トリム修正値を用いて、タンク2a、2bに設置されているレベル計により測定されたタンク2a、2bの液面レベルを修正する。【選択図】図1
