We developed a contemporary vehicle for transporting liquefied natural gas (LNG) used
in implementing modern promising cryogenic technologies for airspace, aviation and
other industries. We conducted a search for optimal solutions when selecting the design
of load-bearing members in the assembly consisting of the vessel, the shell and the frame
of the tank car and the tank container, ensuring reliable vehicle functioning during oper-
ation. The study validates design choices for a system of cut-off safety devices and high-
speed valves for incident prevention during vehicle operation. Based on the investiga-
tions conducted, we suggest a means of storing liquefied natural gas in a vehicle tank,
which ensures safe LNG vapour release from the tank into the atmosphere during rail-
road or road transportation. We present a technology of discharging LNG at the custom-
er's site that ensures minimal LNG vapour release into the atmosphere. For the first time
we supply a description and performance specifications for promising transportation de-
vices, such as 40 cubic meter tank cars for LNG and ethylene.
