What does internal flooding originate from?

• A. Outside the ship
• B. From ballast tanks
• C. From rainwater on deck
• D. Inside compartments due to hull damage

Answer: (D)

Internal flooding means water has entered and is accumulating in the ship’s internal spaces because a hull breach or damage has allowed seawater to invade the interior. The initiating event is damage that creates openings in the ship’s structure, letting water get into compartments from within, and then it spreads through contiguous spaces. That distinguishes it from water that merely comes from outside the ship or from deck rain or ballast tanks—not the interior damage that starts the flooding.
