 · Free surface effect is the destabilizing effect of liquids on ships. When a partially filled tank also known as slack tank is tilted, the liquid inside the tank moves to the lower side of the tank. If not corrected or if the mass of the liquid is very high, then the ship can capsize. Hence, it is an important effect to consider.

 · W (GMsin p - GG2 cos p tan p) = W (GM - GG^ sin p. Thus the effect of the movement of the liquid due to its free surface, is equivalent to a rise of GG2 of the centre of gravity, the 'loss' of GM being: Free surface effect GG2 = pfI1/pV. Another way of looking at this is to draw an analogy with the loss of stability due to the suspended weight.

 · Free surface effect (MAR 6 Rev.03/01/01) Factors affecting free surface effect If the free surface formula is considered it is obvious that the breadth of the tank is the most important factor. If a tank is subdivided …

Free surface effect is the change in stability of a vessel caused by liquids moving about freely in a tank or hold. As a vessel rolls, liquids in tanks or breached compartments accentuate the roll by moving freely from side to side of the tank accumulating first on one side and then the other, and may adversely affect the stability of the ship. ...

 · As can be inferred from Fig. 14, Fig. 15, Fig. 16, the free surface effect diminishes rapidly with submergence depth. Based on Dawson, the free surface effect on submarine hydrodynamics is negligible for h D > 3 and completely disappears for h D > 5. The interaction between the free surface and the submarine hull is significant at the ...
