Q

Why is gas-freeing rarely required for LPG cargo tanks?

🔍 Key Concepts

• Purpose of gas-freeing a cargo tank (when and why it’s done) • Typical cargo handling practices on LPG carriers (dedicated service vs many different cargoes) • Difference between LPG cargo properties and the need to change cargo types

💭 Think About

• Ask yourself: In what situations do tanker crews normally have to gas-free cargo tanks? Is it more about inspections, changing cargoes, or the nature of the product? • Consider how LPG carriers are usually operated: Do they routinely switch between many unrelated cargo types, or are they mostly in dedicated service? How would that affect the need to gas-free? • Look at each option and ask: Which one deals directly with the reason gas-freeing is or isn’t needed, instead of talking about unrelated properties like oxygen content or universal compatibility?

✅ Before You Answer

• Verify which statement correctly links tank usage pattern to the need (or lack) to gas-free. • Eliminate any choice that claims LPG has a special chemical property (like high oxygen content or universal compatibility) that you know is not accurate for LPG. • Confirm that the remaining choice explains why the need to change cargo types is limited on LPG ships, reducing the need for gas-freeing.
