Question 1313 Deck General

The correct answer is C) cargo pump discharge rate. The combined fan discharge rate in an inert gas system is related to the cargo pump discharge rate because the inert gas system is designed to maintain a positive pressure in the cargo tanks during cargo operations. The combined fan discharge rate must be sufficient to keep up with the maximum cargo pump discharge rate to ensure an adequate supply of inert gas is provided to the cargo tanks. The other options are incorrect because they are not directly related to the design of the inert gas system. The boiler forced draft fan rate, shoreside loading rate, and size of the largest cargo tank do not determine the required combined fan discharge rate of the inert gas system.
