DC Interference Testing and Mitigation of New Electrically Isolated Pipelines Installed within Congested Existing Pipeline Network

摘要：

　　Congested existing buried piping or pipeline networks ”within” or ”close to” old plant facilities such as, gathering centers, booster stations, pipeline manifolds, etc.are normally electrically continuous to each other and are protected by common impressed current cathodic protection (CP) systems.However, new Pipeline/piping sections installed at such congested network are sometimes required to be electrically isolated from existing pipelines and are provided with separate impressed current CP systems.This paper discusses, methods implemented in design, installation, testing and commissioning of CP system of electrically isolated new pipeline sections, with special emphasis on DC stray current interference due to existing anode ground beds and existing pipelines crossing/parallelism.Case studies are included, with discussions on results of interference testing, interference mitigation, post interference mitigation surveys and protective potential surveys.
