Optimization of Cathodic Protection on Offshore Structures
Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...

متن کاملNumerical Calculation of Cathodic Protection Potential Distribution for Ocean Construction
Using FEM during the design of cathodic protection system can optimize the cathodic protection system and forecast the distribution of potential in real marine environment. A single bar was modeled for which protection was provided by an anode located in different places. Through analysis of each unit and synthesis in the whole area, mathematical model of 3-D finite element was constructed. Pot...
متن کاملEffect of Alternating Current on the Cathodic Protection and Interface Structure of X80 Steel
This study employs potential-monitoring techniques, cyclic voltammetry tests, alternating current (AC) voltammetry methods, and surface characterization to investigate the AC corrosion of cathodically protected X80 pipeline steel. In a non-passive neutral solution at pH 7.2, a sufficiently negative potential completely protects steel at an AC current density of 100 A/m². In an alkaline solution...
متن کاملAnalysis of Stray Current Induced by Cathodic Protection on Steel- Framed Masonry Structures
Cathodic protection (CP) has been successfully employed to protect steel-framed masonry buildings from corrosion related damage. When a CP system is installed to protect the structural members, other metallic items which are within the fabric of the structure but are not in direct electrical continuity may suffer from stray current interactions, resulting in accelerated corrosion of the discont...
