Vanmok LD Studio

Vanmok LD Studio – Pipeline Leak Detection Software

In order to increase the safety of the pipeline and preserve environment from potential leaks, Vanmok has developed Pipeline Leak Detection Software, which can detect leaks ranging in size from 0.5% of nominal flow rate (such as leaks from pinholes) to ruptures within 200 meters** accuracy in a short span of time (less than few minutes). Vanmok LD™ Studio works with traditional SCADA systems.

Unlike incumbent technologies that fail to detect small leaks and Cry Wolf, Vanmok LD provides reliable system for detecting leaks as small as pinholes.

Our leak detection system is specialized in distinguishing between the column separation and leak and sends only True Positive Alarms. In addition to distinguishing between the column separation and leak, in the instances that both a leak and column separation occur, Vanmok LD™ Studio predicts leak (segment, leak percentage and leak location) as well as the timing of the inception and evolution of column separation.

Vanmok LD™ Studio Specifications
Connectivity/Interface	Uses Industry-standard interfaces Rapid Integration with SCADA/DCS/PLC/RTU
Regulations/Standards Compliance	Meets and exceeds the requirements of API 1130
Sensor/Instrumentation Requirement	Can be deployed on all pipeline segments and no intermediate sensors required with in 250km

Vanmok LD™ Studio Performance
Sensitivity	Minimum detectable leak size is up to 0.5 % of the nominal mainline flow rate. Detection time window is less than 90 minutes for leaks < 1%. Detection time window is less than 5 minutes for leaks > 5 % of the nominal mainline flow rate, including ruptures.
Accuracy	Leaks can be localized within ±200 meters* regardless of leak size from pinholes to ruptures
Reliability	No nuisance/false alarms for steady state and transient operating conditions.
Robustness	In the event of instrumentaion failure (i.e, pressure, flow and temperature transmitters loss or failure, pump lock outs and valve status change), Vanmok LD maintains its leak detection funtionality without degradation

LEAK Detection

Vanmok LD is capable of accurately locating the detected leak by application of numerical methods that derives the leak location. Under most operating conditions the location accuracy is highly acceptable for applications such as theft detection and small volume leak detection. Leak Spotter™ helps in leak detection and localization.

Theft Detection

Vanmok LD™ technology can be used effectively for theft detection by precisely locating the hot tapping by thieves within 200 meters ** in less than a few minutes.

RUPTURE DETECTION

The rupture detector within LeakSpotter™ uses built-in logic to discover any abrupt signature of big leak events and simultaneously distinguish it from other possible sources of those abrupt changes, such as varations in the pipeline’s operating conditions.
