Oil transportIMAGE: The new research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect. Petersburg Polytechnic University Underground pipelines that transport oil and gas are very important engineering communications worldwide.
Some of these underground communications are built and operated in earthquake-prone areas. Seismic safety or seismic stability of underground pipelines began to be intensively studied since the s. Since then, a number of methodologies were proposed for calculating stress received by an underground pipeline during an earthquake.

The purpose of these methodologies was to make an accurate prediction on the structural stress received by a pipeline during source earthquake, and thus it would allow to decide how resilient the pipeline must be made in the first place. It is important to find a right balance between pipeline cost and its structural resilience.
Turns out, we were wrong. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect.

Disregard of the longitudinal stress oil transportation methods that all oil and gas underground pipelines are more susceptible to earthquakes than was initially expected. Researchers have developed a new theory oil transportation methods the seismic wave propagation process in an underground pipeline and surrounding soil to address this problem.
The related theoretical material that explains all the mathematical calculations of the new theory and its benefits in comparison to predecessor methodology can be found in the article Wave Theory of Seismic Resistance of Underground Pipelines. Yet the ominous concern is that all our current pipelines are at risk will stay for some long time until they are replaced and modernized" mentioned Karim Sultanov from Institute of Mechanics and Seismic Stability of Structures Academy of Sciences of the Republic of Uzbekistan. The research results in the article.]
Quite right! Idea excellent, I support.
The properties turns out
Remarkable question
I consider, that the theme is rather interesting. I suggest you it to discuss here or in PM.
It is already far not exception
