Basic Concept of Damage Stability and Watertight Subdivision
Damage to a vessel which compromises the watertight integrity of the hull will lead to ingress of water into the compartment(s) of the vessel. The flooding consequent to the broaching of the watertight skin of the ship will affect the attitude of the vessel, i.e. trim, draught and heel, and the stability characteristics will be affected, usually for the worse. The ‘remaining’ stability after sustaining damage is known as residual or damage stability.
