Aboveground Pipeline Leak Detection
Above-ground pipeline leak detection is crucial to preventing loss of product, environmental damage, and fines. Undetected leaks often result in a loss of product, environmental damage, fines, and infrastructure damage not to mention the potential safety risk uncontrolled leakages pose.
HAWK's above-ground pipeline integrity monitoring system uses Fiber Optic Sensing technology, which detects the occurrence of a leak and gives an accurate location for rapid in-field assessment and repair. As the sensing element is passive it may be installed in any hazardous location and extremely hot and cold applications. It also has a high degree of accuracy, making it possible to detect small changes in temperature and strain along the pipeline. This can help operators identify potential issues before they become major problems, saving time and money on repairs and maintenance. As a leading provider of above-ground pipeline leak detection, HAWK can assist you with all your needs.

Fibre Optic Sensors (FOS)
- Have a very low cost per meter
- Are non-intrusive (do not contact the fluid)
- Can identify leakage, intrusion, and theft
- Give presence and precise location of an event
- Work in real time, 24/7 - 365 automatically
- Require no additional infrastructure to operate
- Have little to zero maintenance once commissioned
- Can handle runs of up to 80km sensing vibration, temperature, and strain
Frequently Asked Questions
The two Key words are Time of Flight and Rayleigh Backscattering,
i. Backscattering is the return light from minute imperfections in the fibre, as physical changes such as temperature, strain and vibration act of the fibre the spectrum of this return light is altered. Rayleigh Backscattering is the part of this spectrum that responds to vibration which allows vibration in the field to be taken out of the return light.
ii. Time of Flight is like a sonar, laser or radar, in that the time the pulse is traveling relates to a distance, in Fibre optic sensing this is a not just taken at the reflection point but for every bit of the fibre the pulse travels though.
Both! Our system can be installed below the ground or above.
The Fiber Optic System continually monitors large spans of pipeline, looking for vibration and temperature changes. Once a detection occurs, the system alerts the operator or security personal to the exact location of disturbance in the pipeline.
Yes, we encourage it in fact! We have specially made systems that are shipped all over the world specifically for technology trials.
