Russian scientists develop a technology to rapidly assess condition of structures in the Arctic

20 december 2023

Scientists of the Geological and Geophysical Faculty of Novosibirsk State University (NSU) have developed a technology for rapid assessment of the condition of structures in the Arctic and permafrost territories.

The complex for evaluating structures and storing the data consists of sensors that record the frequency and amplitude of buildings. After measuring the amplitude of the vibrations, it is possible to determine the state of the structure.

"In this way, we investigated a number of transport and engineering infrastructure facilities in the Novosibirsk region, as well as at one of the largest metallurgical enterprises in Russia. The results of our research were 100% confirmed by other, more time-consuming and expensive methods," said Alexander Kvashnin, Director of the Center for Technology Transfer and Commercialization at NSU.

When this technology undergoes pilot tests at large enterprises in Russia, it will be used in pipeline transport networks, oil and gas production and more, gazeta.ru reports.
