Simulate using your data

The range of possible situations that can occur on a pipeline can be considered using simulation methods.  Measurements of the state of a pipeline's condition can be used for a detailed, simulation-based analysis.  This defect-by-defect analysis can account for the uncertainty in measurements and variation in conditions on the line. 

Measurements of pipeline defects using methods such as in-line inspection can be incorporated into a defect-by-defect, simulation-based analysis that determines the probability of failure for each defect. For failure causes such as corrosion and cracking, the PIRAMID models use Monte Carlo simulation to consider the uncertainty in the defect measurements, pipe properties, and operating conditions at each defect location. This means that each defect is individually simulated millions of times within PIRAMID to account for these uncertainties.
   
By aggregating these simulation results, PIRAMID reports the current failure probability for each defect and projects how the failure probability will increase in future years due to growth of the defect. This includes specific probabilities of failure for small leaks, large leaks and ruptures to assess the impact of the different failure sizes. 

 
The failure rate for a given defect is calculated at each year into the future for each failure mode (small leak, large leak and rupture).
