Your ship has loaded 8,000 barrels of gasoline at a cargo temperature of 36°C (97°F). API gravity is 54°. The volume correction factor (VCF) is .0006. You are bound for New Jersey from Ecuador. How many barrels would you expect to unload if the cargo temperature is 55°F at the discharge port?
Official USCG Answer & Rule Citation
Correct Answer: Option A — 7,798
The temperature drop is 42°F (97°F to 55°F). Using the volume correction factor (VCF) of 0.0006 per degree, the total shrinkage factor is 42 × 0.0006 = 0.0252. The volume reduction is 8,000 × 0.0252 = 201.6 barrels, leaving 7,798.4 barrels.
