How to Use This Calculator
- Enter Number of Tanks, Tank Diameter, and Tank Height.
- Set Roof Type and Maximum Fill Level.
- Review the Total Operating Capacity (bbl) result.
- Use Shell Capacity per Tank (bbl) and Operating Capacity per Tank (bbl) to inform your decision.
- Use the chart to visualize the results and explore different scenarios by adjusting inputs.
How the result changes with Tank Diameter
| Tank Diameter | Total Operating Capacity |
|---|---|
| 49 | 83,429 bbl |
| 147 | 750,857 bbl |
| 264 | 2,421,757 bbl |
| 361 | 4,528,319 bbl |
What each input means
- Number of Tanks
- Total number of storage tanks in the tank farm.
- Tank Diameter
- Internal diameter of each tank in feet. Common sizes: 100–300 ft for crude storage.
- Tank Height
- Shell height of each tank in feet. Typical range: 36–64 ft.
- Roof Type
- 0 = Cone/fixed roof (loses ~1 ft usable height), 1 = Floating roof (loses ~2 ft).
- Maximum Fill Level
- Operational fill limit as a percentage of usable volume. Typically 85–95%.
