damage stability

Damage stability in nautical science refers to a ship's ability to remain afloat and upright after sustaining hull damage that causes flooding. Naval architects design ships with watertight compartments to limit the spread of flooding. International standards, like the "one-compartment" or "two-compartment" standard, dictate how many compartments can be breached without sinking the vessel.12

A critical factor is "free surface effect," where unconfined water in flooded areas can exacerbate a ship's tilt. Excessive heel can be disastrous, leading to capsizing. Modern regulations aim to ensure ships can withstand probable damage scenarios and maintain stability, even if some flooding occurs.12
