This work analyzes the methods of dismantling and demolition of reinforced concrete structures, namely: manual, mechanical and semi-mechanical method, drilling and blasting method, thermal method. The main advantages and disadvantages of these methods, the possibility and economic feasibility of their use in the interests of the Ministry of Defense of the Russian Federation are also considered. On the basis of the analysis carried out, taking into account the limitations of the use of the methods, a promising electro-hydraulic pulse method for dismantling reinforced concrete structures was proposed and the necessary conditions for its implementation in industrial mastabs in the interests of the Ministry of Defense were indicated.

The types of Autonomous stationary energy-cooling systems designed for complete isolation of special objects operating without connection with the atmosphere are Considered. A technical solution is proposed that allows increasing the efficiency of the energy-cooling system, reducing the consumption of process water due to its partial recirculation for cooling the engine of an Autonomous power plant, as well as increasing the period of complete isolation of the object.

The authors of the article developed an autonomous energy supply system for remote military facilities and settlements using liquefied natural gas. A characteristic feature of the developed system is a simplified constructive design of cryogenic equipment for liquefied natural gas, increased reliability and service efficiency of an autonomous energy supply system, as well as the possibility of independent operation of a gas engine and a boiler station from each other.
