What do gas compressors on an LNG vessels provide the motive force to do?

🔍 Key Concepts

• Function of gas compressors on LNG carriers – think about what systems need gas under pressure • Difference between boil-off gas handling and cargo circulation/warming • Operations during loading vs. discharging vs. tank cool‑down/warm‑up

💭 Think About

• For each option, ask: in that specific operation, is compressed gas actually required, or could it be done by another system (like pumps or natural flow)? • Consider where boil‑off gas must be sent during normal sea passage and how it gets there. • Think about which operation (warming tanks, sending gas to engines, sending gas ashore) definitely could NOT be done without compressors.

✅ Before You Answer

• For each choice, identify what medium is moving (liquid LNG vs. vapor/boil‑off gas) and whether that normally needs compression. • Verify which systems on LNG carriers are specifically designed to raise gas pressure and where that gas is routed (engine room, shore, cargo tanks). • Check if any choice describes a task usually done by cargo pumps rather than by gas compressors.
