Which type of flooding occurs when damaged spaces flood due to holes through interior bulkheads and piping, compromising watertight integrity?

• A. Localized flooding
• B. Progressive flooding
• C. Backflow flooding
• D. Patching flooding

Answer: (B)

Progressive flooding describes how water spreads from the initially damaged area into adjacent compartments as watertight barriers are breached by openings like holes in interior bulkheads and piping. When these openings exist, water has a path to move from one space to another, weakening multiple compartments and allowing flooding to advance beyond the first hit. In this scenario, the damaged spaces flood precisely because holes through bulkheads and piping compromise the ship’s watertight integrity, enabling the flood to progress through connected spaces. Localized flooding would stay confined to one space if the barriers remained intact, which isn’t the case here. Backflow flooding involves water moving backward through systems due to pressure changes, not the outward spread through breached compartments. Patching flooding isn’t a standard term for a type of flooding; patching relates to stopping flooding.
