Your ship has loaded 20,000 barrels of crude oil, departing Valdez, Alaska for San Francisco. When loaded the cargo temperature was 96°F. API was 15°. The volume correction factor (VCF) is .0004. If the cargo temperature is expected to be 56°F at the discharge port, how many barrels will be offloaded?

Question

Accepted Answer

Option A: 19,680. A temperature drop of 40°F (96°F to 56°F) causes the crude oil to contract. The volume reduction is: 20,000 barrels × 40°F × 0.0004 (VCF) = 320 barrels. Subtracting this from the loaded quantity results in an expected offload volume of 19,680 barrels.
