Deck General USCG Question #4852 (Set 153)

Your ship departed Venezuela for New York, loaded with 10,000 barrels of crude oil, whose average cargo temperature was 30°C (86° F). API is 25°. The volume correction factor (VCF) is .00045. If this cargo is heated to 100°F prior to discharge, how many gallons will you offload?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 422,646

Heated volume expands by $14^\circ\text{F}$, totaling $10,063$ barrels at discharge. Converting barrels to gallons ($10,063 \times 42$) yields $422,646$ gallons, accounting for thermal expansion during transit under standard marine bulk liquid carriage protocols.
