Abstract
Recommended practices and specifications for Cathodic Protection (CP) do not include well defined methods or formulas for how to handle anode interference. Anode interference occurs when anodes are mounted close to each other and will reduce the current output pr anode. The loss of anode current will depend on distance between anodes, the number of anodes, whether the anodes provide local or remote protection, etc. Different methods found in literature are described and compared with results from CP modelling. Clarification on the most important influence factors will be given and recommendations for methods to handle anode interference will be proposed.
