🔍 Key Concepts

• Reliquefaction plant purpose on gas carriers (LNG/LPG) – what is its main job during the voyage? • Difference between voyage operations (in transit) and port operations (cool-down before loading, vapors during loading). • Relationship between boil‑off vapor, tank pressure, and returning liquid back to cargo tanks.

💭 Think About

• Ask yourself: When the ship is at sea, what happens to cargo that warms up slightly and produces vapor? How is that vapor handled on ships fitted with reliquefaction plants? • Are tank cool‑down before loading and handling vapors generated during loading normally considered the primary function of a reliquefaction plant, or are they separate procedures/systems? • Which option best describes the core, continuous role of the reliquefaction plant, rather than occasional or auxiliary operations?

✅ Before You Answer

• Check which choice directly mentions controlling pressure and temperature during transport, and whether that matches the typical description of reliquefaction systems on gas carriers. • Verify whether pre‑cooling tanks and lines before loading is usually listed as a function of the reliquefaction plant, or as a separate cool‑down operation using cargo or shore facilities. • Confirm if handling vapors specifically during loading is the main design purpose of a reliquefaction plant, or if it is primarily intended to manage boil‑off gas during the voyage.
