Induced voltages

What guidance is available on voltages induced in pipelines by HVDC powerlines?

Australian Standards so far only address induced voltages from AC powerlines, via Part 1 Appendix Q and AS/NZS 4853. However the Canadian Association of Petroleum Producers in 2014 published a useful document on HVDC effects: Influence of High Voltage DC Power Lines on Metallic Pipelines. Due to the increasing development of renewable energy projects and associated HVDC powerlines it is likely that this topic will be addressed in future revisions of AS 2885 and/or AS/NZS 4853.
