Telluric and ocean current effects on buried pipelines and their cathodic protection systems

摘要

Pipelines are subjected to telluric activity due to the modulation of the earth's magnetic field by solar particles. This report describes two methods for modeling telluric currents in pipelines wherein the distributed source transmission line (DSTL) model has been used successfully to predict the magnitude of telluric currents and the associated potential variations throughout pipeline networks.
