Leaks can be caused by third-party intervention, ground movement or corrosion, but also by improper operating procedures and material failure. PSIpipelines provides several methods for leak detection and location.
The selection of appropriate methodology depends upon instrument availability, field devices, communication infrastructure, transported fluids and gases and performance criteria. PSIpipelines Leak Detection System does not depend on special instrumentation and field devices, but the overall system performance improves if integrated with ultra-fast scanning sensors and dedicated Leak Remote Units with sufficient processing power.
In combination with statistical analysis PSIpipelines Leak Detection System provides model-based methods:
and methods that utilise the signature of a leak:
Methods are optimised to detect and to locate leaks accurately during steady state, shut-in and transients operations for onshore and offshore pipelines of all sizes. The different methods can be deployed in parallel in order to ensure the highest possible reliability.
PSIpipelines Leak Detection System is the most accurate solution for long distance pipelines with intermediate pumps, extreme elevations and slack line flow conditions. It is compliant to international and industry standards including
The Leak Detection System is also certified by all TÜV organisations.
Any invalid measurements or field device malfunctions will not cause a shutdown of the PSIpipelines Leak Detection System. All leaks are clearly indicated and presented via the graphical user interface. This interface is highly customisable and provides significant information to the operator. Leak warnings and alarms are also sent to the SCADA system.
