RECONSTRUCTION OF THE UNDERWATER PASSAGE

The modern state of pipeline transport is characterized by a long period of operation, as a result of which ensuring the stable functioning of main pipelines, as well as maintaining their safe and reliable operation, become one of the most important and priority tasks of the operation of the pipeline system.
Ensuring efficient and reliable operation of main pipelines can be achieved by conducting timely repair work, equipment renovation and reconstruction. Carrying out repair and renovation of equipment is aimed at maintaining the design technical condition, while reconstruction allows to achieve improvement of technical and economic indicators, as it is carried out based on modern solutions developed taking into account the latest achievements of science and technology. The reconstruction of individual pipeline sections allows for the renewal of capital assets in a shorter time and with lower costs than with new construction. Also important is the fact that in the process of reconstruction, new technologies and constructive solutions are implemented, as well as the latest technology, and such socially significant problems as improving working conditions and environmental protection are solved [1, 2].
