Cathodic protection (CP) mitigates the high cost of steel corrosion and other alloys in seawater and seabed sediments. Marine Corrosion and Cathodic Protection is a comprehensive guide of corrosion issues and presents theories to tackle common offshore code-based CP designs. Advanced theory is developed for non-routine CP applications, with and without subsea coating systems.
The interactions between CP and the fatigue and hydrogen embrittlement characteristics of alloys are explained. Sacrificial (or galvanic) anodes and impressed current systems are examined, which is followed by descriptions of successful and unsuccessful applications on petroleum installations, harbours, jetties, pipelines, windfarm foundations, ships and FPSOs. Retrofit CP systems for the life extension of assets are evaluated, together with methods for applying CP internally in both static and flowing systems. A critical review of the role of physical and computational modelling in CP design and evaluation addresses the more geometrically complex applications. Techniques for, and limitation of, CP surveying, inspection and monitoring are explained in the context of system management.
This text is ideal for engineers, designers, manufacturers, equipment suppliers and operators of offshore CP systems.
