Inspections Track Software For Oil and Gas Inspection Industry
Fuel oil storage tank calibration is one of the most critical tasks in the oil and gas industry. Accurate calibration ensures correct volume measurement, eliminates revenue loss, and maintains compliance with safety and metering standards. Because even a slight miscalculation can cost thousands, it’s essential to understand how tank strapping and calibration work—and how modern inspection tools simplify the entire process.
In this guide, we’ll walk through how to calibrate a fuel oil tank, what tank strapping means, which methods are used, and why digital solutions like Inspections Track Software make the process more efficient and error-free.
Tank calibration is the process of determining the exact volume of a storage tank based on its dimensions. It verifies how much fuel the tank holds at each height level.
Tank strapping refers to creating a tank capacity table (strapping chart) that maps the liquid height to the corresponding volume.
| Liquid Height (mm) | Volume (Litres) |
|---|---|
| 100 | 1,250 |
| 300 | 3,760 |
| 500 | 6,420 |
| 700 | 9,150 |
| 900 | 12,000 |
This table becomes a reference point for operators, inspectors, and custody-transfer teams.

Before calibration begins, inspectors must:
Tip: Modern solutions like Inspections Track Software store historic data, drawings, and previous calibration logs, ensuring faster preparation.
There are two primary industry-approved methods:
Using measuring tapes or laser devices, inspectors measure:
This method is traditional but prone to human error.
The tank is filled with measured quantities of water or fuel while recording:
Although accurate, it requires more time and resources.
Most modern inspections now prefer 3D laser scanning and automated data capture.
Accurate measurement is crucial. Inspectors typically record:
Digital calibration using 3D scanning improves accuracy by up to 95% compared to manual methods.
After measurements are collected:
This strapping chart becomes the official reference document for operations.
Quality assurance teams verify:
Finally, a full calibration report is created.
However, manually compiling these reports is time-consuming—this is where automation becomes essential.

The oil and gas industry is rapidly moving toward digital-first inspections. Inspections Track offers a modern, cloud-based solution to manage calibration tasks effortlessly.

Because calibration requires accuracy and compliance, using a dedicated inspection platform helps minimize errors, reduce paperwork, and ensure consistency across all tank sites.
To ensure reliable results, always follow these guidelines:
Fuel oil storage tank calibration and tank strapping are essential for operational accuracy, financial correctness, and compliance in the oil and gas sector. While manual methods still exist, digital tools—especially Inspections Track Software—are transforming the process with automated workflows, better accuracy, and instant reporting.
By integrating digital inspection management with proper calibration techniques, companies can significantly improve their metering reliability and operational efficiency.

Tank calibration ensures accurate volume measurement of fuel storage tanks, helping prevent financial loss and ensuring compliance with industry standards.
Most tanks should be calibrated every 3–5 years, or sooner if structural changes, repairs, or deformation are observed.
Calibration is the process of measuring a tank’s capacity, while tank strapping refers to creating the capacity table that shows volume-to-height readings.
