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

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

Accepted Answer

Option A: 19,680. Crude oil volume decreases as temperature drops from 96°F to 56°F, creating a 40°F difference. Multiply 20,000 barrels by 40 and the 0.0004 VCF to find a 320-barrel contraction. Subtracting this from the initial 20,000 barrels gives 19,680 barrels expected at the discharge port.
