The development of gas network, transportation and power facilities created the interference issues to the urban gas pipelines from alternating current (AC) power lines. Due to the limited space in urban area, the widely used of AC mitigation methods face great challenge when applied to urban gas pipelines. AC mitigation for urban gas pipelines has become more and more problematic. This study attempted to exemplify the AC mitigation design practice for an urban gas pipeline by numerical calculation, including AC interference risk evaluation, AC mitigation design and mitigation effectiveness assessment. Field tests were conducted to collect data along the pipeline right-of-way (ROW) and evaluate the risk of AC interference. Based on the collected information, a computing model was also established for pursuing the most cost-effective and environment-friendly mitigation methods. At last, the effectiveness of such AC mitigation was assessed through field tests.
