The validity of commonly employed formulas for the ohmic resistance of sacrificial anodes are analyzed based on fundamental considerations. These formulas, which may appear to work under specific situations, are likely to fail if the anode geometry and design criteria are altered according to varying environmental and operating conditions and structural details related to offshore constructions. Alternate equations, which are thought to be more generally applicable, are proposed and compared with the available field data for a few, relevant anode geometries.
