Abstract
Comparative analysis of pipeline construction methods in the seismically active zone, ensuring their reliability
Incoming article date: 26.06.2025The article presents the concept of ensuring reliability during the operation of oil pipelines in an active tectonic fault zone. Possible solutions to this problem are considered. It is noted that at the present stage in the Russian regulatory and technical documentation, when calculating pipelines for seismic effects, a sharp displacement of the soil is not taken into account, leading to a violation of their design position. Using the example of the research object, changes in the stress-strain state of a pipeline with specified pipe wall thicknesses and plate displacement during an earthquake were considered. The minimum distances for the installation of shut-off valves in the area of the pipeline passing through a tectonic fault were determined. The total amount of economic and environmental damage from possible accidents on the oil pipeline under study has been determined, which allowed us to conclude that an integrated approach is needed to ensure the reliability of oil pipelines in the zone of an active tectonic fault.
