What is free surface effect & how to prevent free surface effect at ship?

It is an effect occurs when the liquid moves across the tank in the direction of heel, making the centre of gravity moves away from the centerline, reducing the righting lever and increasing the angle of heel.

The movement of the centre of gravity has been caused by the transfer of a wedge of liquid across the tank, so the righting lever was reduced. While the righting lever is reduced, it is useful to assume the effect of free surface is to raise the centre of gravity, so reducing the metacentric height of gravity.

In a design point of view, the tanks with a longitudinal centerline division can reduce the free surface effect. Also, in practical view, pressing up tight tanks can prevent the liquid from moving across inside tanks.
