Question 580General Subjects - Assistant Engineer

The correct answer is A) The two-speed main sea water circulating pump can be used for this purpose. In a flooding emergency, the two-speed main sea water circulating pump can be used to pump out the main machinery space bilge. This pump is typically designed with the capability to operate at a higher flow rate to serve as an emergency bilge pump in addition to its normal cooling water circulation duties. The other sea water pumps, such as the auxiliary sea water circulating pump or the single-speed main sea water circulating pump, may not have the necessary capacity or design features to effectively dewater the machinery space in an emergency situation.
