Referring to the illustrated steam plant sea water cooling system drawing, what statement is true concerning main circulating to auxiliary circulating sea water system cross-connect capability? Illustration SP-SW-01
AI Explanation
The correct answer is 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.
This is correct because the sea water cooling system drawing shows a cross-connect capability between the main circulating sea water system and the auxiliary circulating sea water system. This allows the pumps from each system to be used interchangeably to provide cooling water to the various heat exchangers, providing redundancy and flexibility in the event of a pump failure.
The other options are incorrect because they either do not fully capture the cross-connect capability (C and D), or they make assumptions about the specific use of the pumps that are not clearly shown in the illustration (B).
