Claim One:
1. A method for assessing a corroded pipeline defect, the method comprising: obtaining, by a pipeline analysis computing device, a plurality of observed defect growth rates from inspection data collected at different time intervals, wherein the inspection data comprises partial defect growth rate information; determining, by the pipeline analysis computing device, at least one unobserved defect growth rate on the basis of distribution pattern of the plurality of observed defect growth rates; simulating, by the pipeline analysis computing device, a condition of at least one hyper parameter on the inspection data based on prior information of the at least one hyper parameter; simulating, by the pipeline analysis computing device, the plurality of observed defect growth rates and the at least one unobserved defect growth rate based on the simulated hyper parameters; obtaining, by the pipeline analysis computing device, a defect growth rate point estimate from the simulated growth rate data; and obtaining, by the pipeline analysis computing device, a probability of failure of a defect from the defect growth rate point estimates; and scheduling, by the pipeline analysis computing device, an inspection of the defect based on the obtained probability of failure.
