AIGF Exit Exam • Set 10 Question 7 of 30

What are the cases Internal pressure in Liquefied gas fuel containment safety principles ?

✓

Direct Answer

Option A: both (a) and (b)

Internal pressure design criteria under the IGF Code require that the design pressure (Po) must not be less than the gauge vapour pressure of the fuel at 45°C, nor less than the Maximum Allowable Relief Valve Setting (MARVS). This ensures the tank safely contains fuel during temperature fluctuations.

All Options

both (a) and (b) (Correct Answer)

Po shall not be less than the gauge vapour pressure of the liquefied gas fuel at a temperature of 45°C

Po shall not be less than MARVS

none of the above

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Training for Ships subject to the IGF Code (AIGF).
