While underway with full LNG cargo tanks, an alarm indicates liquid in hold space #3. What should be the first action taken?

🔍 Key Concepts

• LNG carrier safety procedures for cargo leaks • Difference between detecting/assessing a potential leak and taking corrective action • Dangers of sending personnel into a space that may contain flammable gas and low oxygen

💭 Think About

• Before doing anything, what information do you need to confirm whether there is actually a dangerous leak or just an instrument indication? • Which actions could make a gas leak situation worse by adding ignition sources or exposing people to hazard? • In a suspected gas leak in an enclosed or semi-enclosed space, what are the usual priorities: measurement/monitoring, personnel safety, or immediate cargo transfer?

✅ Before You Answer

• Verify which option focuses on assessing conditions (pressure/temperature/atmosphere) before major actions are taken • Check which choices might endanger personnel or change the condition of the system without first confirming the situation • Eliminate any option that involves entering a potentially unsafe space before its atmosphere and structure are verified as safe

While underway with full LNG cargo tanks, an alarm indicates liquid in hold space #3. What should be the first action taken?

immediately commence lining up the system to educt LNG from the cargo hold and prepare to jettison LNG from cargo tank #3

check the temperature and pressure indicators in the hold space

commence purging hold #3 with inert gas

send someone into the hold space with SCBA and cryogenic immersion suit, to investigate the condition of the hold
