Coating failures and CP shielding; Localized corrosion at coating defects; Permeability of coatings 1C - AC corrosion of pipelines. Pitting corrosion at high AC current densities; AC induced coating disbondment; Interference on CP performance; Online monitoring and assessment technique; DC corrosion of buried pipelines 1D - Stress corrosion cracking of pipelines. Fundamentals of pipeline SCC; Steel metallurgy and welding metallurgy and crack initiation; Circumferential SCC; Hydrogen-induced cracking of high-strength pipe steels 1E - Internal corrosion of pipelines. Under-deposit pitting corrosion and microbial corrosion; Corrosion in oil-water emulsion and oil-water-sand slurry flow; CO2 corrosion fundamentals; High-performance inhibitors 1F - Corrosion, fracture and microbial corrosion of coiled tubing in service fluids 2. Pipeline Integrity 2A - Prediction of pipeline failure pressure and determination of fitness-for-service. ILI data analysis and prediction of pipeline failure pressure by defect assessment; Multi-physics field coupling model for fitness-for-service analysis; Modeling of defect growth 2B - Modeling of steel tubing corrosion in CO2 storage (supercritical CO2 environments) 2C - Modeling of tubular corrosion in SAGD/CO2 co-injection and production systems 3.
