Internal flooding differs from external flooding in that internal flooding ?

Internal flooding differs from external flooding in that internal flooding ?

• A. Originates outside the ship through hull breaches
• B. Originates inside compartments due to hull damage
• C. Occurs only in dry docks
• D. Is always less dangerous

Answer: (B)

The main idea is where the water sources begin. Internal flooding refers to water that starts inside the ship’s compartments—originating from failures in internal systems, such as ruptured pipes, leaking ballast or seawater lines, or damaged equipment—so the flooding fills spaces from within the vessel. This is different from external flooding, where seawater enters from outside through a hull breach. Because the water comes from inside, damage-control actions focus on isolating and stopping internal sources and sealing off affected compartments, then pumping out the water. The statement that best captures this is that the flooding originates inside compartments due to internal damage, rather than coming in from outside.
