Question 1219 Deck General

The correct answer is C) maximum cargo pump discharge rate. The combined fan discharge rate in an inert gas system is related to the maximum cargo pump discharge rate because the inert gas system must be able to maintain a positive pressure in the cargo tanks in order to prevent the ingress of air. The inert gas system's capacity is designed to match the maximum rate at which cargo can be pumped out of the tanks, ensuring that sufficient inert gas is available to displace the cargo vapors and maintain the inert atmosphere. The other options are incorrect because they are not directly related to the sizing of the inert gas system. The boiler forced draft fan rate, size of the largest cargo tank, and shoreside loading rate may influence the system design, but the primary factor is the maximum cargo pump discharge rate.
