Question 1164 Deck General

The correct answer is A) blower failure. The automatic shut down valve at the outlet of the gas production plant is designed to close automatically upon blower failure. This is because the blower is responsible for generating the necessary pressure to deliver the inert gas through the gas main. If the blower fails, the inert gas supply will be disrupted, and the automatic shut down valve will close to prevent any potential backflow or pressure issues in the system. The other options, such as deck seal low water level, low inert gas temperature, or cargo pump failure, are not directly related to the automatic shut down valve's primary function, which is to safeguard the inert gas supply in the event of a blower failure.
