API 1130 Compliance

Computational Pipeline Monitoring (CPM) Features identified by API 1130 second edition November 2002.
(Taken from API 1130 with attributes supported by LT 2000 commented after each discussion)

The CPM listed below are not in any particular order nor is there any attempt to weight the importance of each. It must be noted that no one methodology or particular application posses all of these features and certain features will be more appropriate for specific pipeline systems. A CPM system must have at least one of these features.

The CPM system may:

1. Possess accurate commodity release alarming.
   LT 2000 customer satisfaction

2. Possess high sensitivity to commodity release.
   LT 2000 customer satisfaction

3. Allow for timely detection of commodity release.
   LT 2000 customer satisfaction

4. Require minimal software configuration and tuning.
   LT 2000 customer satisfaction

5. Perform its CPM functions with existing sensors and instruments (or does not require additional requirements or instrumentation).
   LT 2000 requires only a minimum of instrumentation which most pipelines already have.

6. Be minimally impacted by communication outages or data failures.
   LT 2000 is only minimally effected.

7. Accommodates complex operating conditions.
   LT 2000 has not encountered any operating conditions it can not accommodate

8. Be available during transients.
   LT 2000 supported

9. Be configurable to complex pipeline networks.
   LT 2000 customer satisfaction

10. Perform an imbalance calculation on meters at one instant in time.
    LT 2000 supported

11. Possess dynamic alarm thresholds.
    LT 2000 supported

12. Possess dynamic liquid pack constants.
    LT 2000 supported

13. Accommodate commodity blending.
    LT 2000 supported

14. Account for heat transfer.
    LT 2000 does not support

15. Provide the pipeline system’s real-time pressure profile.
    LT 2000 supported

16. Accommodate intermittent or permanent slack line conditions (avoiding alarms and not totally disabling all segments of the pipeline during event).
    LT 2000 does not support

17. Accommodate all types of liquids.
    LT 2000 supports a wide range of liquid products

18. Identify leak location with appropriate mile post locations or nearest station.
    LT 2000 supports

19. Have the ability to display pressure history versus time for each line pressure location along a pipeline.
    LT 2000 supports

20. Provide for automatic and manual data substitution during periods of data non-availability (e.g., communication outage, measurement failure, maintenance, etc.).
    LT 2000 requires the SCADA system to provide any alternate data source.

21. Provide composite indication of data attributes associated with supporting field inputs and calculated data.
    LT 2000 does not support but SCADA provider might.

22. Minimize the number of alarms by requiring supporting and preferably independent, commodity release confirmation.
    LT 2000 does not provide

23. Identify the leak rate.
    LT 2000 does not provide rate but does provide barrels.

24. Accommodate commodity measurement and inventory compensation for various correction factors (temperature, pressure, density, meter factor).
    LT 2000 does not provide volume correction from measurements but by using interface arrival at a designated location versus the computed location and adjusting pipeline volume accordingly.

25. Provide batch tracking with interface location, be able to compute bulk modulus and perform inventory compensation.
    LT 2000 provides

26. Perform calculations quickly using data immediately as it becomes available.
    LT 2000 provides

27. Validate commodity release alarms using redundant analysis within the same method as well as redundant analysis between methods.
    LT 2000 does not provide

28. Accommodate pump start-ups/shutdowns, valves opening/closing, and other normal operational functions without generating alarms.
    LT 2000 provides

29. Account for effects of drag reducing additive.
    LT 2000 calculation is not effected by DRA.

30. Offer efficient field and Control Center support.
    LT 2000 has very satisfied customers

31. Contain a leak probability analyzer to weigh all of the components of a leak (linepack loss, pressure/flow deviation, meter shortage) to assist a pipeline controller in making a leak declaration.
    LT 2000 provides

32. Possess ability to allow alarms to be integrated into the pipeline controller’s alarm processing.
    LT 2000 provides

33. Possess audit trails of CPM actions taken by pipeline controllers and allow saving of historical data.
    LT 2000 provides

34. Have the ability to return to normal delectability limits rapidly after data or computer service is restored or after an unscheduled interruption.
    LT 2000 provides

35. Have the ability to provide various types of warnings and alarms for example warnings or alarms on data failure or unusual operating conditions that indicate the cause is not a commodity release.
    LT 2000 does not provide

36. Provide an alarm under all operating conditions and will not be disabled or turned off automatically regardless of circumstance.
    LT 2000 provides

37. Have the ability to automatically self test without effecting performance while test is underway.
    LT 2000 does not self test.
