Vanmok LD Configuration
Cloud Based Leak Detection Technology
Vanmok LD Studio Specifications and capabilities |
|
| Leak detection Sensitivity | • Minimum detectable leak size up to 0.5% of 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% nominal mainline flow rate, including ruptures. |
| Leak Localization Accuracy | Leaks can be localized within ± 200 meters for all leak sizes from 0.5% to ruptures. |
| 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 pipeline segments as long as 250 km with no intermediate sensors. |
| Modules | Leak Spotter: Leak detection and localization ColumnFinder: Column separation prediction and localization VanmokGIS: Visualization of leak location and area contamination with the help of Maps and terrain VanmokTrend: Trending tool to review and plot historical data over days, weeks and months in addition to live data for decision making by frontline pipeline controllers or analysts. |
| Functions | Works under all operating conditions for leak detection and localization as well as column separation: • Transient states: Including pump start/stops, valves opening/closing, line packing and unpacking, delivery change‐overs. • Steady state ‐ normal operation • During pipeline Shut-in, Start Up and Shutting down. |
| Columnfinder Functions: | • Accurately predicts the location of column separation and amount of vapor bubble along the location. • In addition to pin point the location and estimate the vapor bubble along the mainline, it can also trend the evolution of vapor bubble with time at any selected locations. • It can show the evolution of Column sep. due to cooling during extended shut-in period and also while the mainline is being started from shut-in. |
