BULK CARRIER VENTILATION - CAPTAIN PAUL R. WALTON
 KNOWLEDGE TO ELEVATE
Moisture damage is a source of many cargo claims. Claimants allege that it is brought about by the ship’s failure to ventilate correctly, resulting condensation (known as ‘sweat’). This sweat can seriously damage the quality of bulk cargoes like grain, seedcake and steel surfaces. Cargo sweat is condensation forming on the surface of a ‘cold’ cargo as warm, moist air enters the cargo hold.
To avoid the possibility of cargo sweat, ventilators should be closed and no ventilation carried out. However, if the moisture content of the cargo is high, extraction of the moist air from within the cargo holds may be required. Ship’s sweat is the result of condensation forming on the ship’s structure as the ship becomes colder moving from a hot to a cold climate. For ship sweat to occur, the dew point in the cargo hold must exceed the temperature of the ship’s structure. To prevent this, cargo should be ventilated if the ship is moving from a warm to a cold climate. The shipper’s declaration should contain sufficient information about the cargo, particularly its moisture content (MC), transportable moisture limit (TML) and ventilation requirements, especially if the commodity is not normally carried or the areas of trade are uncommon.
Claims for moisture damage to cargo can only be defended if supported by properly maintained documentation. Records of hold temperatures, humidity and durations of ventilation are essential. The dew point temperature of the cargo hold and outside air should be compared. If the outside dew point temperature is lower or equal to the cargo hold, then ventilation should be continued. Ventilation not only controls sweating, it can also control gases or odours emitted from cargo. If there is a risk of seawater spray or rain entering the cargo holds, ventilation should be stopped and times noted until conditions change, allowing resumption of ventilation, even at night if required. If possible, there should be regular inspections of the cargo space for any signs of condensation and a complete record of cargo hold temperatures and ventilation should be kept.
