LNG (Liquefied Natural Gas) has matured rapidly as a clean fuel in the global energy market. SSLNG (Small Scale LNG) is a new method for more convenient transferring LNG from production plants to the end users. the challenge related to the SSLNG business is a relatively expensive supply chain due to the absence of economies of scale. 
In this Study, a novel method for LNG transportation in the supply chain has been presented. the main idea of this method is to use the mobile LNG containers for exportation & importation in order to improve and facilitate the process of transportation of LNG in economical way, such as elimination of regasification units in the course of loading/offloading of LNG. 
Also in this paper, suitable materials for cryogenic fluid is invested and the proper size of conceptual model of mobile containers with consideration of being practical and easy handling are proposed.
The multi layers arrangement for the suggested containers are Invar, Polyurethane foam and Polyamide and etc. The container sizing also has been selected equal to ISO (International Standard Organization) 40 ft size containers. A conceptual model using finite element method (FEM) for the suggested container has been created. An analysis using ABAQUS CAE 2016 Software has been applied to investigate on the conceptual container strength under periodic loads during charging and discharging containers with LNG.
