- Improper Ventilation Continues to Drive Cargo Damage Claims.
- Accurate Ventilation Records Critical for Grain and Oil Seed Carriage.
- Night Ventilation Remains a Key Area of Dispute.
In its latest Risk Watch, Britannia P&I Club has shed light on the persistent risk of cargo damage during the transport of grain and oilseed cargoes, emphasising the critical need for proper ventilation practices, reports Safety4Sea.
Common Causes of Cargo Claims
Jobin Mathew, the Assistant Loss Prevention Manager at Britannia P&I, points out that many cargo claims related to grain and oilseed shipments often stem from issues like wetting, mould, and caking damage. While cargo interests frequently cite improper ventilation as the culprit, it’s not always the real issue. Sometimes, damage can arise from the natural characteristics of the cargo itself or from wetting and defects that occurred before shipment.
Importance of Correct Ventilation Practices
Cargo interests often hold incorrect ventilation responsible for damage, which makes it crucial for vessels to ensure that cargo holds are ventilated properly and that accurate ventilation records are kept. Britannia P&I suggests following the three-degree ventilation rule for grain and oilseed cargoes instead of relying on the dew point rule, as measuring dew point conditions accurately in loaded cargo spaces can be quite tricky.
Challenges Around Night Ventilation
Night ventilation often sparks debate. It can be tough to manage due to the risk of unexpected rainfall and the limited availability of crew members to react swiftly. In some instances, the design of ventilation inlets might restrict the effectiveness of short, passing showers.
When Night Ventilation May Be Justified
In certain situations, such as when sailing through areas prone to seasonal rains or when bad weather is on the horizon, it might be reasonable to skip night ventilation. However, it’s essential to document this decision clearly in the ventilation log, backed up by logbook entries and supported with both documentary and photographic evidence.
Cargoes Requiring Continuous Ventilation
For specific cargoes, especially bagged rice transported from warmer climates to cooler regions, continuous ventilation is vital whenever weather conditions and ventilation guidelines allow. Consistent failure to ventilate at night under favourable conditions, without rain or sea spray, may be used against the vessel in the event of cargo damage claims.
