Question 74Safety & Environmental - 1st Asst/Chief
70% to passOn a tanker vessel, what is the required combined capacity of the inert gas generating system as compared to the total capacity of all the cargo pumps which can be operated simultaneously?
A50%
B75%
C100%
D125%
AI Explanation
The correct answer is D) 125%. According to the regulations, the combined capacity of the inert gas generating system on a tanker vessel must be at least 125% of the total capacity of all the cargo pumps that can be operated simultaneously. This ensures that the inert gas system can adequately maintain the required inert atmosphere in the cargo tanks during cargo operations. The other options are incorrect because they do not meet the 125% requirement specified in the regulations. A 50% or 75% capacity would be insufficient, while 100% would just match the total pump capacity without providing the necessary safety margin.
