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

Correct Answer: Option A — It is possible to use the auxiliary circulating pump to supplement the main circulating pump(s), and it is possible to use the main circulating pump(s) to supplement the auxiliary circulating pump.

System flexibility is achieved through interconnected piping arrangements. Main and auxiliary circulating pumps are often sized to allow mutual supplementation. This design ensures that if one pump fails, the other can maintain necessary flow rates to heat exchangers, adhering to marine engineering principles for reliable auxiliary cooling.
