SPECIAL FORTIFICATION STRUCTURE Russian patent published in 2017 - IPC E04H9/12 F41H11/00 F02G1/04 

FIELD: construction.

SUBSTANCE: in the full isolation mode, the power supply of a special fortification structure 1 is ensured by the operation of a gas diesel (standalone power station) 2. Thermostating is provided by the operation of the refrigerating machine 3 and the air conditioning system 4 connected thereto through the coolant circuit 5 with the pump 6. After cooling the gas-diesel engine 2 and the refrigerating machine 3, the process water is heated and drained into the reservoir of process water 9, which results in gradual increase in the entire mass of process water in the reservoir 9. For the gasification of liquefied natural gas supplied from the reservoir 12 to the heat exchanger-evaporator 13, the supply of process water from the process water reservoir 9 is provided to the heat exchanger-evaporator 13 via the main line 19 by the pump 20. Warm process water from the process water reservoir 9 passes through the heat exchanger-evaporator 13, gives its heat (through the heat exchange surface) to the liquefied natural gas, as a result of which the warm process water is cooled, and the cold process water enters the process water reservoir 9. As a result of this process, the process water temperature in the process water reservoir 9, which was obtained by cooling the gas-diesel engine 2 and the refrigerating machine 3, is substantially reduced, which ensures maintaining the refrigeration potential of the process water in the reservoir 9.

EFFECT: extending the functioning time of a special fortification structure, maintaining the refrigeration potential of process water used for cooling the standalone power station and the refrigerating machine in the mode of full isolation due to cooling while gasifying the liquefied natural gas, reducing the concentration of harmful components in exhaust gases due to switching the standalone power station to the gas diesel engine operation mode, increasing the drain-free LNG storage due to accommodating the tank in a room with a heat-insulating layer.
