This project is aimed to study, design and analyze a large transportable vacuum insulated cryogenic vessel that will be attached to a truck in order to keep, maintain and transport by road liquid methane at a temperature of -162 °C.
Considerations such as different pressure loads, dimensions, materials as well as their mechanical properties, constraints, masses, insulation systems and weather-environmental conditions (Northern Europe) are made in the mechanical analysis.
Furthermore, calculations and dimensions satisfy the requirements given by the Swedish Standards Institute (S.I.S) following the standards SS-EN 13530-1: Cryogenic vessels – Large transportable vacuum insulated vessel; Part 1: Fundamental requirements and SS-EN 13530-2: Cryogenic vessels – Large transportable vacuum insulated vessel; Part 2: Design, fabrication, inspection and testing.
The CAD software Pro/Engineer Wildfire 4.0 is used to visualize the models for the chosen designs. In addition, the finite element module Pro/Mechanica is used to obtain results of mechanical analyses in order to determine if the stresses are within margins.
