A tanker is loaded with 8,000 barrels of fuel oil. The temperature of the cargo is 50°F. API gravity is 37°. The volume correction factor (VCF) is .0005. What is the net amount in gallons of cargo loaded?
• Barrels to gallons conversion (how many gallons are in one barrel of oil?) • Difference between gross volume and net volume when temperature correction is applied • How a Volume Correction Factor (VCF) is used with temperature to correct cargo volume
• First, convert the total barrels of cargo to gallons before any temperature correction. What simple multiplication do you need? • Think about whether the VCF is applied as a multiplier or as a change per degree. How does temperature difference from the reference temperature affect volume? • Compare how much the corrected (net) volume would change from the gross volume. Should it be slightly higher, slightly lower, or much different?
• Be sure you are using the standard barrel-to-gallon conversion used in tanker cargo calculations • Confirm whether the VCF is being applied correctly: is it per degree of temperature difference or a direct factor? • After your correction, double-check that the net gallons you get is reasonably close to the original gross gallons, not drastically different.
