Leak Detection

Detect leaks faster and with confidence

Detecting a leak quickly and effectively can be limited by a systems level of sensitivity, accuracy, reliability and robustness.

The OptaSense pipeline monitoring system eliminates the guesswork that compromises safe and reliable pipeline management by detecting and locating leaks accurately and in real time, regardless of fluctuating pipeline conditions.

Detect smaller leaks faster with superior sensitivity

Internal leak detection systems are one of the most commonly used methods to detect a leak. These systems use point sensors to track flow rates, as well as provide mathematical and statistical computations of pressure, temperature and product characteristics. Although these systems are useful in identifying leaks, it takes longer to detect them, while small leaks may go completely undetected.
Where point sensors lack in sensitivity, the OptaSense pipeline monitoring system offers a leak detection application that identifies smaller leaks faster—allowing you to eradicate minor issues before they become major incidents. In fact, our fiber-based system can detect small leaks 10 times faster than internal systems—allowing you to detect a 0.1% leak size within a matter of minutes.

Locate leaks with increased accuracy

Another issue with many internal systems and sensors is their inability to identify the location of a leak. With internal systems, leaks are determined by analyzing discrepancies between predicted and measured values. For accurate computational modeling, these systems require a large number of point sensors to monitor the extended range of a pipeline. Due to cost, sensors are only installed in increments along key areas of the pipeline, which limits their coverage and reliability.
With DAS technology, the fiber cable acts as a physical sensor, offering thousands of detection points along the pipeline, capable of accurately pinpointing the location of a leak within 10m, in real time.

Increase confidence in alarm reliability

Point sensors not only struggle to detect and locate leaks, calibration errors and fluctuating pipeline conditions can impact a system’s reliability—resulting in false alarms, missed leaks, or an unnecessary shutdown. Nuisance alarms are also an issue with many external fiber-based systems because they rely on a single detection method, such as temperature.
To minimize the costly impact of an unreliable system, the OptaSense leak detection application validates leaks before sounding an alarm. Using a patented multimode leak detector, our system confirms suspected leaks by measuring changes in noise, temperature, pressure, and ground strain simultaneously and in real time. These multimode detector settings can be customized to specific environments and operating states across every 10m section.

Rely on robust system performance

Today’s complex pipeline networks require robust systems that perform under changing fluid compositions, temperatures and pressures, which for many internal systems often result in computational errors and false alarms.
The OptaSense pipeline monitoring solution eliminates these issues by delivering a system that performs under transient, slack-line, and multiphase flow conditions. Even when critical pipeline infrastructure goes offline, this fiber-based system ensures continuous and reliable event detection, classification and location.
