Influence of the level of cathodic protection on the corrosion fatigue properties of high-strength welded joints

摘要

Existing guidance on the design and construction of offshore installations does not define the optimum level of cathodic protection (CP) and notes that the effectiveness of CP has not yet been proven for structural steels with a yield stress above 400 Mpa. There is clearly a need to establish the optimum and safe working limits of CP in realistic environments if higher strength steels are to be more widely employed in offshore structures.
