🔍 Key Concepts

• Inert gas system safety trips on tankers • The purpose of the deck water seal and scrubber cooling water • Why high inert gas temperature going to cargo tanks is dangerous

💭 Think About

• Think about what conditions would make it unsafe to keep sending inert gas to cargo tanks and therefore should automatically stop the blowers, not just give an alarm. • Ask yourself which items listed are directly tied to preventing flame or hot gases from reaching the cargo tanks. • Consider whether these protections work independently, or if several of them are typically grouped into one automatic shutdown logic.

✅ Before You Answer

• Verify which conditions in an inert gas system cause an automatic shutdown of blowers, not just an alarm. • Check the role of water seal integrity and cooling water in preventing backflow of hot gases to the tanks. • Confirm whether high delivery temperature limits to cargo tanks are part of the automatic trip conditions in standard tanker IGS arrangements.
