Corrosion is a major cause of structural deterioration in the marine/offshore industry. FOr that reason, reliability assessment and maintenance planning of these structures are crucial. In the current work a combination multi-phase phenomenological and mechanistic model for pitting corrosion is tested using Bayesian network (BN) approach.
Corrosion features in energy pipelines can adversely affect the stress/strain state of the pipe body leading to potential integrity concerns. This study demonstrates the application of Reliability-Based Surrogate Models as a means of integrating FEA and reliability analysis in a more reasonable timeframe for integrity programs.
