What is Understanding Free Surface Effect in Ships about?
Free surface effect occurs when liquid in a partially filled tank shifts during vessel rolling, raising the center of gravity and reducing stability. This can be minimized through compartmentalization, keeping tanks nearly full, and dewatering tanks after incidents. The virtual reduction in metacentric height due to free surface effect is derived as the ratio of the second moment of area of the free surface to the vessel
