Deck General USCG Question #1333 (Set 42)

Which tanker discharge pattern would be the safest and most efficient?

Official USCG Answer & Rule Citation

Correct Answer: Option D — Start discharging with most of the discharge coming from forward, but include some from midships and after tanks

Discharging primarily from forward while maintaining some discharge from midships and aft keeps the vessel trimmed by the stern. This pattern prevents excessive bending stresses (hogging or sagging) and ensures cargo continuously flows toward the suction wells for efficient pumping.
