Abstract

The prevention of failure in subsea pipelines has been a priority of users in many fields. Through prognosis, the Remaining useful life (RUL) of pipes can be predicted, and with proper maintenance techniques, its RUL can be extended. Subsea pipelines may experience fatigue failure due to cracks initiated as result of corrosion and cyclic stress. Hence, there is a need for estimating remaining useful life once the crack is detected. To ensure this, a proper prognostic will be developed predicting the RUL of these pipelines. A generic MATLAB framework will be developed to ensure easy prognostics of the pipelines. This framework will investigate the effects of crack orientation and magnitude of stress on the RUL. It will also investigate the effect of uncertainty in the initial crack estimation to RUL prediction.
