🔍 Key Concepts

• Corrosion and marine growth inside sea water passages when equipment is idle • Role of drain valves vs. vent/air-cock valves when emptying a shell-and-tube exchanger • Difference between leaving a system full, empty, or fresh-water filled for long lay‑up

💭 Think About

• Think about what happens to stagnant sea water if it is left standing inside a metal heat exchanger for weeks or months. • Consider what must happen to allow sea water to drain completely from a low point drain – what else besides the drain valve might need to be opened? • Ask yourself whether simply draining is enough, or if there is a good reason to flush with something else before an extended lay‑up.

✅ Before You Answer

• Verify which choice prevents internal corrosion and marine growth during long idle periods. • Check which option would allow the heat exchanger to drain freely without creating a vacuum or air lock. • Confirm whether marine practice usually recommends leaving sea water systems full of sea water, completely empty, or filled with fresh/treated water for extended shutdown.

When securing a sea water-cooled shell-and-tube heat exchanger for an extended period of time, what statement represents the recommended operating procedure?

The sea water side of the heat exchanger should be left completely filled with sea water.

The sea water side of the heat exchanger should be drained by opening the drain valves, while insuring that the vent valves remain closed while draining.

The sea water side of the heat exchanger should be drained, then flushed with fresh water and left completely filled with fresh water.

The sea water side of the heat exchanger should be drained by opening the drain valves, while insuring that the vent valves remain open while draining.
