Achieving Maximum Crack Remediation Effect from Optimized Hydrotesting

The project will develop a working model to allow industry to predict the overall benefits of hydrotests. Such a prediction will be 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 best parameters that would generate the most effective crack remediation.
