🔍 Key Concepts

• Liquefied Natural Gas (LNG) tank behavior during storage • How stratification by density/temperature can occur in cargo tanks • What operational events cause a sudden rise in boil-off gas in LNG carriers

💭 Think About

• Think about which option involves a change inside a single tank that could lead to a sudden increase in vapor formation. • Ask yourself: which description is specific enough to be a defined phenomenon, rather than just a routine operation? • Consider which choice would present a significant safety and pressure-control problem that needs a special name in LNG operations.

✅ Before You Answer

• Does the option involve layers of liquid with different densities or temperatures in the same tank? • Would this situation logically cause a sudden spike in boil-off vapor rate and tank pressure? • Is the choice describing a named hazard/phenomenon, rather than a normal cargo operation like transfer or custody handover?
