Deck General · Cargo — Sweat & Ventilation
'Ship's sweat' that damages cargo forms when:
- ACargo is overheated by the engine room
- BCargo is loaded too quickly
- CThe bilge pump runs too long
- DWarm, moist air inside the hold condenses on cooler steel structure as the vessel moves to a colder climate✓ Correct
Explanation
Ship's sweat is condensation on the hold's structure when the steel is colder than the dew point of the hold air—typical sailing from a warm to a cold region. Proper ventilation (or dehumidification) using the dew-point rule prevents wetting of cargo; cargo sweat forms on the cargo itself in the reverse case.
