Question 712Steam Plants - Assistant Engineer

The correct answer is B) Start the lube oil system, engage the turning gear, start the condensate and circulating pumps, start the gland sealing system and second-stage air ejector. This is the correct sequence because it follows the standard procedure for raising vacuum on the main propulsion plant prior to getting underway. The lube oil system must be started first to ensure proper lubrication, then the turning gear is engaged to slowly rotate the main engine. Next, the condensate and circulating pumps are started to begin the flow of cooling water. Finally, the gland sealing system and second-stage air ejector are started to remove air from the system and establish the necessary vacuum. The other options are incorrect because they either start components in the wrong order or include unnecessary or incorrect steps, such as starting the first-stage air ejector or failing to engage the turning gear.
