Tank free surface moment calculation

WebJan 16, 2024 · where i = the second moment of the free surface about the centre line, in m4 w = the ship's displacement, in tonnes p = the density of the liquid in the tank, in … In a normally loaded vessel any rolling from perpendicular is countered by a righting moment generated from the increased volume of water displaced by the hull on the lowered side. This assumes the center of gravity of the vessel is relatively constant. If a moving mass inside the vessel moves in the direction of the roll, this counters the righting effect by moving the center of gravity towards the lowered side. The free surface effect can become a problem in a craft with la…
