This cluster of papers focuses on the modeling, risk analysis, and reliability assessment of corrosion in steel pipelines, particularly addressing pitting corrosion. It covers topics such as the effect of corrosion on pipeline integrity, reliability assessment methodology for pipelines with active corrosion defects, and the development of new models for predicting corrosion damage. The research also delves into the impact of corrosion on offshore and marine steel structures, as well as the use of advanced techniques such as finite element analysis and fuzzy inference systems for pipeline risk assessment.
