🔍 Key Concepts

• Density stratification in liquid cargo tanks • Behavior of liquefied gases or petroleum cargoes when temperature and density layers change • Difference between a gradual loss of cargo and a sudden internal mixing event

💭 Think About

• Think about what happens when a colder, heavier layer of cargo forms above a warmer, lighter layer in a closed tank. What eventually causes these layers to mix? • Which term is associated with a sudden, sometimes violent, internal circulation of liquid within the tank, rather than loss of cargo to the atmosphere or burning? • Eliminate any options that mainly describe external fire behavior or gradual vaporization instead of internal tank stratification.

✅ Before You Answer

• Identify which option specifically refers to sudden mixing of stratified liquid layers in a tank. • Verify which term is commonly used in connection with LNG (liquefied natural gas) or liquefied gas carriers and tank stability issues. • Rule out terms that primarily describe fire spread or normal vapor loss processes, not internal circulation.
