🔍 Key Concepts

• Hygroscopic cargo (cargo that absorbs moisture from the air) and how it reacts to temperature and humidity changes • Difference between cargo sweat (condensation on cargo) and ship sweat (condensation on ship’s structure) • Effect of moving from warm to cold climates on dew point and whether to ventilate cargo holds

💭 Think About

• Think about what happens to warm, moist air in the hold when the ship moves into colder outside air—where will condensation tend to form? • Ask yourself: when is ventilation helpful—when outside air is cooler and drier than hold air, or when it is cooler but still very moist? • Consider how a hygroscopic cargo can be damaged: is it more at risk from moisture in the air, or from condensation forming on the ship’s steel and dripping down?

✅ Before You Answer

• Be clear on the definitions: cargo sweat vs. ship sweat and where each forms • Check whether warm-to-cold increases or decreases the risk of ship sweat vs. cargo sweat when you introduce outside air • Verify when the dew point of outside air compared to the cargo/hold temperature tells you to ventilate or keep holds closed

Your vessel is going from a warm climate to a cold climate with a hygroscopic cargo. Which statement is TRUE?

There is danger of heavy cargo sweat if you ventilate.

You should ventilate; there is little danger of ship sweat, but a possibility of cargo sweat.

You must ventilate constantly and vigorously to combat ship sweat.
