Abstract
This paper focuses on advanced analysis techniques
and design considerations of DC interference generated by HVDC electrodes
during normal bipolar and temporary monopolar operations on neighboring
metallic utilities, with a special emphasis on buried gas and oil pipelines. This
study examines the level of pipeline corrosion, the safety status in the
vicinity of exposed appurtenances and the impact of DC interference on the integrity
of insulating flanges and impressed current cathodic protection (ICCP) systems.
Computation results obtained for different soil models show that different
soils can lead to completely different DC interference effects. The results and
conclusions presented here can be used as a reference to analyze the severity
of DC interference on pipelines due to proximate HVDC electrodes.
