🔍 Key Concepts

• Dew point vs. surface temperature and when condensation forms • How sweating (ship’s sweat/cargo sweat) damages dry cargoes • Goal of cargo hold dehumidification: keep air conditions so moisture does NOT condense on cargo or steel

💭 Think About

• Think about what happens when warm, moist air touches a cooler surface. At what relationship between dew point and surface temperature will water start to condense? • If you want to avoid condensation on cargo or steel, should the air’s dew point be higher, lower, or the same as the surface temperature? By about how much for a safety margin? • Which choice would clearly increase the risk of condensation forming on the cargo or ship’s structure?

✅ Before You Answer

• Review that condensation happens when surface temperature is at or below the dew point of the surrounding air • Identify which options make dew point higher than surface temperature (these increase condensation risk) • Identify which option gives a sensible safety margin between dew point and the cargo/steel surface temperature to prevent sweating
