Question 1 of 27070

A vessel is equipped with cross-connected deep tanks. In which situation should the cross- connection valve be closed?

🔍 Key Concepts

• Free surface effect in partially filled tanks • How cross-connected tanks act as one large tank when the valve is open • Difference in stability risk between full, empty, and partly filled tanks

💭 Think About

• In which condition will liquid be able to move freely from side to side between the two tanks? • How does a partly filled tank affect a vessel’s transverse stability compared to a full tank? • When would closing the cross-connection valve reduce the dangerous free movement of liquid?

✅ Before You Answer

• Identify which answer choices involve liquid versus dry cargo • Check which situations describe partly filled tanks, not completely full ones • Decide when the free surface effect would be greatest if the valve were left open
