ROLE OF HAZARDOUS GEOLOGICAL PROCESSES IN OPERATION OF THE CHAYANDA-ESPO OIL PIPELINE
The relevance of the work is caused by the importance of ensuring the smooth operation of pipeline transport, which determines the energy and economic security of the country. Manifestations of hazardous geological processes can cause pipeline failures, with consequences ranging from injury/death, e...
