Q

Your vessel is loaded with nonhygroscopic cargoes and is going from a cold to a warm climate. Which action should you take to avoid sweat damage while on the voyage?

🔍 Key Concepts

• Cargo sweat vs. ship sweat – understand the difference and when each occurs • Effect of moving from a cold to warm climate on hold air and cargo temperature • Ventilation rules for hygroscopic vs. nonhygroscopic cargoes

💭 Think About

• Ask yourself: In a cold-to-warm voyage, which is colder – the cargo or the outside air – and what kind of sweat does that create? • Think about whether bringing in warm, moist outside air over a colder cargo will increase or decrease condensation on the cargo. • Consider how the ventilation rule of thumb differs between hygroscopic (moisture-absorbing) and nonhygroscopic (non-absorbing) cargoes in changing climates.

✅ Before You Answer

• Identify whether the main risk here is cargo sweat (moist air condensing on cold cargo) or ship sweat (moist air condensing on cold steel), given the temperature change described. • Confirm whether nonhygroscopic cargo will absorb moisture or if any condensation will remain on its surface. • Check which option either reduces the amount of warm, moist air contacting the cold cargo or avoids introducing additional moisture into the hold.
