Referring to the illustrated steam plant sea water cooling system drawing, which pump can be used to pump out the main machinery space bilge in a flooding emergency? Illustration SP-SW-01 Illustration SP-SW-01: the U.S. Coast Guard has not released this illustration.

Correct Answer: Option C — The two-speed main sea water circulating pump can be used for this purpose.

Large two-speed main sea water circulating pumps are often designed with a suction connection to the machinery space bilge. In a flooding emergency, the pump can be aligned to draw from the bilge, utilizing its high capacity to dewater the space when standard bilge pumps are insufficient.
