WebJan 28, 2024 · The lever that causes the righting of a ship is the separation between the vertical lines passing through G and B1. This is called the Righting Lever, and abbreviated as GZ (refer to the figure above). An important relation between metacentric height (GM) and righting lever (GZ) can also be obtained from the figure above. 2. Neutral Equilibrium:

WebThe size of the righting lever increases with the ship's inclination. In other words, up to a certain angle of inclination (usually between 40° and 60°), the more the ship lists, the greater its tendency to return to an upright position.

WebApr 11, 2024 · Concept of Free Surface Effect. When a tank on the ship’s centreline is not completely full of liquid, and the ship heels, the liquid in the tank moves across the tank in the same direction as the direction of heel. … WebRIGHTING MOMENT (t-m) = GZ (m) x DISPLACEMENT (t) At any angle of heel, it is the horizontal disposition of G and B that determines the GZ value. As a ship progressively heels over the righting lever, GZ, increases to some maximum value and then decreases until at some angle of heel it becomes negative i.e. it becomes a capsizing lever.

WebIf the centre of gravity (G) of the ship shown was lower, the righting lever (GZ) would be larger and the ship would be more stable (since the righting moment would be larger!).
