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? (SP-SW-01)

Correct Answer: Option A — 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-connects in seawater cooling systems are designed for redundancy. Per 46 CFR Subchapter F, auxiliary systems must maintain cooling capacity during pump failure. Utilizing seawater service pumps to supply auxiliary heat exchangers ensures continuous operation of critical machinery, preventing overheating when the dedicated auxiliary circulating pump is unavailable.
