LNG containment insulation performs all of...

🔍 Key Concepts

• LNG cargo containment systems and what the insulation is physically in contact with • Difference between thermal functions (heat transfer, temperature protection) and atmospheric properties (like dew point, humidity) • Structural role of insulation in supporting cargo tank loads and hull protection

💭 Think About

• For each option, ask: Is this something insulation can realistically do as a material around a cold cargo tank? Think about heat, strength, and temperature effects. • Consider where the dew point is normally controlled on a gas carrier: is it mainly by insulation, by ventilation/drying systems, or by cargo handling procedures? • Which functions are clearly about heat flow and temperature and which are more about mechanical/structural support? Does insulation have both roles in LNG tanks?

✅ Before You Answer

• Verify which options clearly relate to heat transfer and temperature protection of the hull and cargo. • Check whether LNG tank insulation is designed to carry loads or support the tank structure in any way. • Think carefully: does insulation directly change the dew point of the hold space air, or does it simply affect how much heat passes between cargo and surroundings?

LNG containment insulation performs all of the following functions, except which of the following?

increases the dew point of the hold space atmosphere

protects the hull against low temperature

limits the heat leak to the cargo

absorbs loads imposed by the cargo
