Cathodic Protection Design Calculation Pdf

An Evaluation of Cathodic Protection Design Calculations. Cathodic protection design reliability depends to a large extent on input parameters used in design calculations. Some of the most important input parameters in these calcu-lations are the electrochemical properties of sacrificial an-odes. The electrochemical efficiency of the anode material is used for weight (lifetime) calculations and the anode poten- tial (driving voltage) is used to, This inconsistency can lead to issues when designing cathodic protection (CP) systems for near shore and shore crossing areas. Figure 1 provides an example of a generic shore crossing design and is divided into three sections: shallow water, shore-water interface and on-land..
