This paper presents the effects of changing physical parameters on the performance of parallel ribbon, sacrificial anode cathodic protection systems for coated pipelines. The mathematical model accounts for the current and potential distributions associated with discrete holidays on coated pipelines that expose bare steel to the environment. Case studies have been selected to show conditions under which a given CP system will and will not protect the pipe. An evaluation of remedial CP system upgrades to enhance the performance of a given system will also be discussed.
