🔍 Key Concepts

• Submerged cargo pumps on LNG carriers operate inside the cargo tank at cryogenic temperatures (about -162°C / -260°F) • Materials and lubricants behave very differently at cryogenic temperatures compared to normal temperatures • Think about what is already available around the pump inside an LNG cargo tank

💭 Think About

• Which option would still remain liquid and effective as a lubricant at very low cryogenic temperatures? • Would adding a separate lubricant be practical or safe inside a cargo tank designed for very pure LNG? • Which choice best matches standard LNG cargo system design, where simplicity and compatibility with the cargo are critical?

✅ Before You Answer

• Check which substances would freeze or thicken at LNG temperatures and become useless as lubricants • Consider which lubricants might contaminate the cargo or be unsafe in an LNG tank • Think about what fluid is continuously present around a submerged pump during normal cargo operations
