A modern design of cryogenic tank container and stationery cryogenic tank is presented in the paper. Mobile cryogenics container tank has been designed for transportation of LNG as well as other liquefied cryogenic gases with the temperature down to –196°C. The analysis included two types of logistics solutions: one involving the transport full container, which is removable from the vehicle and left in the workplace, and the second solution with reloading from mobile tank into simplified container tank or other mobile tank located in the workplace. Simplified container tank and mobile tank have been designed to storage some cryogenics gases as well as mobile container but without transportation of them. Modern and effective insulation materials were applied in the tank structure. Therefore, the liquefied cryogenic gases can be stored for a long time periods. Presented are selected depending on the extent of heat exchange in cryogenic conditions, as well as a model for FEM calculations of thermal insulation inside the tank and supports. Simulation results show the long storage times obtained for a simplified container which are close to the times obtained by stationary tanks, however a lot easier to tran
