A cargo of fuel oil is loaded whose temperature is 66°F. API gravity is 36°. The volume correction factor (VCF) is .0005. A cargo temperature of 80°F is expected at the discharge port. If 9,000 barrels were loaded, how many gallons would you expect to unload?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 380,646
Based on previous calculations, 9,000 loaded barrels expand to 9,063 barrels at an 80°F discharge temperature. Converting barrels to gallons requires multiplying the total barrel volume by the standard conversion factor of 42 gallons per barrel, yielding 380,646 total US gallons expected at the port.
