CHEMCO Exit Exam • Set 8 Question 6 of 30

The fresh air intake of the inert gas system

✓

Direct Answer

Option B: allows the inert gas piping to be used for gas freeing the tanks

The fresh air intake on an IG system allows for the introduction of air, enabling the system to be used for gas freeing operations by purging cargo vapors from the tanks via the IG piping.

All Options

prevents the flue gas from falling below an oxygen content of 3%

allows the inert gas piping to be used for gas freeing the tanks (Correct Answer)

opens when there is excessive vacuum on the deck water seal

enables outside air to mix with and to cool the hot flue gasses

Detailed Explanation & Context

The fresh air intake on an IG system allows for the introduction of air, enabling the system to be used for gas freeing operations by purging cargo vapors from the tanks via the IG piping.
