Statistical Inventory Reconciliation Analysis

Petrolink is pleased to announce that we are now offering SIRA (Statistical Inventory Reconciliation Analysis) to N.S.W and Australia. Petrolink's SIRvey system is a cost effective means to ensure that your site is environmentally sound and is not losing any product from underground storage tanks. SIRvey is easy to use and provides reports that exceed EPA requirements for leak detection in UPS systems. There are no expensive monitoring equipment requirements; all that is needed is information that is generally already available such as dip stick readings and meter totals.

  An Introduction to SIRA

Statistical Inventory Reconciliation (SIR) is a proven methodology to accurately manage fuel inventories. Through and algorithm process, SIR analyses fuel inventory data (sales, deliveries, product levels, and meter readings). From this analysis it is possible to determine:

• Tank and Line Integrity
• Delivery Accuracy
• Tank Tilt / Incorrect Tank Charts
• Miscalibrated Meters
• Pilferage

In underground storage tank (UST) systems, there are three areas where fuel can be lost: sales, deliveries or a leak in the tank and lines. In order to lose fuel through sales, the dispenser pumps more fuel than the meters register.

The only way to lose fuel through deliveries is a discrepancy in the number of litres reported delivered and the number of litres actually received. If the integrity of the tank or line is compromised, then fuel can be lost as a result.

The most common area where fuel losses are identified is in the sales process with the miscalibration of meters. While individual meter miscalibrations may appear to be small and insignificant, the aggregate of these miscalibrations results in the loss of significant profits.
