Achieving Maximum Crack Remediation Effect from Optimized Hydrotesting

This project developed and validated models that will allow the industry to predict the overall benefits of hydrotests. Such a prediction is made with a consideration of various characteristics of a pipeline including the type of operation, stage of cracking, environmental susceptibility, steel metallurgy, and operation history. When hydrotesting is necessary, the model will help operators select the parameters that would generate the most effective crack remediation.
