🔍 Key Concepts

• Carefully trace the piping and valve connections between the sea water service pumps and the auxiliary circulating sea water pump/heat exchangers on drawing SP-SW-01. • Note the presence and direction of flow/check valves that may prevent flow from one system to another even if a line appears connected. • Compare which systems (sea water service, auxiliary circulating, and main circulating) actually have a designed cross‑connect, and which are kept isolated.

💭 Think About

• If the auxiliary circulating pump fails, which pump(s) could still send sea water through the auxiliary circulating heat exchangers using the available cross‑connect valves? • Is there any piping that would allow the auxiliary circulating pump to backfeed the sea water service system, or are check valves/isolating valves preventing that? • Do any lines on the diagram truly allow the main circulating pumps to supply the sea water service or auxiliary circulating systems, or are they only connected to the main condenser loop?

✅ Before You Answer

• Verify exactly where the sea water service pump discharge header ties into the auxiliary circulating system, and whether the necessary cross‑connect valves are shown and can be opened. • Check whether the auxiliary circulating pump suction and discharge have any lines going back to the sea water service manifold that are not blocked by check valves. • Confirm if there is any physical cross‑connection to the main circulating sea water system at all; if not, eliminate any choices that mention main circulating pumps supplying other systems.

In the event of auxiliary circulating pump failure, multiple sea water service pumps may be used to supply both the sea water service system and auxiliary circulating sea water system heat exchangers.

In the event of auxiliary circulating pump failure, multiple sea water service pumps may be used to supply the sea water service, main circulating sea water, and auxiliary circulating sea water system heat exchangers.
