You are fighting a fire in a watertight compartment using hoses and salt water. Why may the stability of the vessel be reduced?

🔍 Key Concepts

• Free surface effect and how water moves in a compartment • How added water in a compartment affects GM (metacentric height) and stability • Difference between downflooding and water accumulation within an already flooded space

💭 Think About

• When you spray large amounts of water into a closed compartment, what happens to that water if the ship heels or rolls? • Which choice directly mentions the effect of water moving side-to-side within a space on the ship’s stability? • Which options describe effects that could happen, but are not the primary direct result of using hoses inside a watertight compartment?

✅ Before You Answer

• Identify which option talks about free surface and metacentric height (GM) specifically • Eliminate any options that do not clearly relate to water sloshing or spreading over a deck or tank surface • Ask yourself: Which option describes an effect that occurs immediately as water accumulates on the deck in that compartment?

Question 1 of 27070

You are fighting a fire in a watertight compartment using hoses and salt water. Why may the stability of the vessel be reduced?

An increase in free surface which reduces the metacentric height

Due to progressive downflooding

Reduction of water in the storage tanks

A reduction of KG to the minimum allowable
