Question 1327Deck General70% to pass
During loading, what is the minimum pressure required to be maintained by the inert gas system on cargo tanks?
AI Explanation
The correct answer is B) 4" water gauge.
According to the regulations governing inert gas systems on cargo tanks, the minimum pressure that must be maintained by the inert gas system during loading is 4 inches of water gauge. This requirement is specified in the International Convention for the Safety of Life at Sea (SOLAS) and the associated International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code).
The other options are incorrect because 2 inches of water gauge is too low, 20 inches is too high, and 40 inches is excessively high for the intended purpose of maintaining a safe, inert atmosphere in the cargo tanks during loading operations.
