The paper substantiates the direction associated with the solution of the interdisciplinary problem of finding ways to improve the reliability and survivability of resource-determining parts and products of equipment operating in the conditions of natural low climatic temperatures of the Northern and Arctic re-gions of the Russian Federation. Prompt provision of services for the repair of worn-out equipment reduces the costs of downtime of production facilities operating in conditions of low climatic temperatures: marine and river marine equipment, port infrastructure, mining, construction and installation, automotive and road construction equipment, pipeline and railway transport. The paper substantiates the need for scientifically based support of the tasks to be solved, not only for the conditions of stationary repair and restoration and welding and assembly complexes of wear-out parts and products of equipment of northern execution, but also for the conditions of their use in mobile complexes.

This paper reveals the features of the operation of river vessels in Yakutia, as well as the technologies used in the repair and restoration of propeller shafts. With the seasonal nature of navigation, it is possible to prevent sudden failures of these nodes during the operation of ships by preventive repairs. The propeller shaft fails for three main reasons – corrosion, wear and fatigue damage. These defects are eliminated by mechanical grinding and subsequent surfacing or welding. Тhe paper shows that the use of scientifically based approaches in the restoration of propeller shafts is a necessary condition for obtaining a high-quality deposited layer.
