Deck General · Cargo Handling & Securing
Grain cargo shifted to one side of a hold during a voyage most directly causes:
- AIncreased draft aft
- BA permanent list and potential capsizing due to loss of positive stability✓ Correct
- CRapid deterioration of the grain due to heat generation
- DHull vibration at the natural frequency of the vessel
Explanation
Grain has a natural angle of repose and can shift in a seaway, especially if the hold is not filled completely. When grain shifts to one side, it raises the center of gravity transversely and creates a heeling moment. Severe shift can reduce GM to zero or negative, leading to capsizing. SOLAS has specific requirements for grain loading and securing.
