A highly reliable rupture detection module that provides the confidence to quickly shut-down a pipeline in the event of a rupture


 

A rupture is a split in a pipeline that requires an immediate shut down. The devastation caused by pipeline ruptures can be extensive and expensive:

  • Loss of life
  • Damage to the environment
  • Clean-up costs
  • Fines

Conventional leak detection methods search for small leaks as well as ruptures. Rupture detection is a backup to the existing SCADA system that is designed to stop pumping should a pipeline rupture occur. The operator could try to restart the pipeline believing that the pump has just tripped, spilling more product through the ruptured pipeline.

Events such as instrument failure or a hydraulic anomaly can cause a false alarm. The operator has little time to confirm a leak before acting to shut down the pipeline. A pipeline shut down is expensive. It loses revenue. The emergency response costs are extremely high. To maintain operator confidence, the rupture module can never issue a false alarm or fail to alarm when a rupture occurs. A rupture detection module should:

  • Not false alarm during any pipeline operations
  • Detect ruptures quickly
  • Detect every rupture, irrespective of its location on the pipeline
  • Alarm even when the rupture trips a pump

A rupture alarm should be treated differently to a leak alarm


 

API 1175 states that potential leaks requiring immediate shutdown are ‘rupture alarms or rupture indications (for example if a unit trips at stations due to low pressure)’. A leak detection system is designed to detect the smallest leak in the shortest amount of time. Rupture detection is designed to detect the unique signature that occurs with a high volume, or high rate of product release.

Rupture detection should be highly reliable, allowing the operator to confidently shut down the pipeline immediately minimizing damage.

 

Why Atmos Rupture Detector is extremely reliable

The rupture module is designed to make the final decision on the occurrence of a pipeline rupture. Atmos Rupture Detector has three separate algorithms to detect ruptures, for a highly reliable system. A rupture occurrence not covered by one algorithm will be detected by another of the three algorithms.

Low KL: Detects near pump stations where the product is easier to pump 

Inventory: Detects on pipelines that can go slack - what comes out is less than what goes in

DMA: Dynamic model analysis (DMA) pattern recognition can detect ruptures on all areas of a pipeline

Atmos Rupture Detector can be installed as an upgrade to an existing Atmos Pipe installation, or as a standalone option. These options provide greater security, assuring the immediate shutdown of the pipeline in the event of a rupture alarm.

Atmos Rupture Detector is included as an option in the latest releases of Atmos Pipe and Atmos Wave Flow statistical volume balance leak detection systems.

Atmos Rupture Detector was tested with data from a variety of different pipeline types and with data from real ruptures that occurred in the past to assure the high level of confidence that every rupture will be detected.
