Question 1 of 2066636ee728f7522a1c5188d2

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 gallons will be offloaded?

🔍 Key Concepts

• Barrels to gallons conversion for petroleum cargo (standard 42 gallons per barrel) • How volume correction factor (VCF) relates temperature change to volume change • Difference between loading temperature and discharge temperature and its effect on cargo volume

💭 Think About

• First, convert the loaded cargo from barrels to gallons before doing any temperature-related corrections. What is the standard conversion factor? • How does a drop in temperature affect volume when you are given a VCF in units of volume change per degree Fahrenheit? Think about whether the volume should increase or decrease. • Compute the total percentage volume change using temperature difference times VCF, then apply that to the original volume. Which answer choice matches your adjusted volume most closely?

✅ Before You Answer

• Confirm the correct gallons-per-barrel value used in all USCG exam problems involving petroleum cargo. • Carefully calculate the temperature difference between loading and discharge ports (which direction is the change?). • Apply the VCF × temperature difference to get a decimal factor (e.g., 1 ± something) and multiply by the original gallons before matching to the closest multiple-choice option.
