Referring to illustrated steam plant seawater cooling system drawing, what statement is true concerning seawater service system to auxiliary circulating seawater system cross-connect capability? See Illustration SP-SW-01

Correct Answer: Option B — In the event of auxiliary circulating pump failure, multiple seawater service pumps may be used to supply both the seawater service system and auxiliary circulating sea water system heat exchangers.

Cross-connect piping arrangements in marine cooling systems are engineered for redundancy. If an auxiliary circulating pump fails, the seawater service pumps are typically sized and valved to provide sufficient flow to both the seawater service system and the auxiliary circulating system heat exchangers, ensuring continued operation of essential auxiliary machinery.
