🔍 Key Concepts

• Stability effects of water accumulation inside watertight spaces • Difference between downflooding from outside vs. water sprayed/contained inside a compartment • How free surface and trapped water affect list and trim of a vessel or rig

💭 Think About

• If you are spraying large volumes of water into a watertight compartment, where does that water go and how does it behave over time? • Which answer choices involve water entering from outside the hull versus staying inside a closed space? • Which option directly describes the most immediate stability effect of a growing pool of water trapped in one compartment?

✅ Before You Answer

• Identify which option refers to external flooding through openings (is that happening here?). • Consider whether firefighting water inside a watertight compartment will more likely change center of gravity (KG) or create an internal free surface/list problem. • Eliminate any answer that doesn’t clearly connect the firefighting water to a realistic, short-term stability consequence.
