Cathodic Protection System Design for Steel Pilings of a Wharf Structure


Corrosion of steel pilings in sea and brackish water is mostly due to the establishment of localized corrosion cells and the effects of the tidal changes. The most frequently used corrosion protection systems are coatings and/or cathodic protection. These protective systems when properly designed, installed and operated are very effective in preventing corrosion problems. The design of a cathodic protection system, in order to be effective and reliable, must take into consideration all technical design criteria, the type of materials used, the geometric shape of the structure, environmental conditions, site restrictions, and any outside interferences. These design considerations, as well as the use of design data and an overall design methodology for a cathodic protection system for pipe and sheet piling used in a wharf structure, are discussed in this paper.
