Abstract
A pressure vessel for transportation of liquefiable petroleum gas (LPG) is cylindrical with a circular cross-sectional profile. The wall thickness of the vessel (in meters) multiplied by a design strength of the material from which the vessel is made (in megapascals) is less than 0.8 times the internal diameter of the vessel (in meters). The design strength is the yield strength divided by 1.5 or the tensile strength divided by 2.5. The wall thickness is between 3 mm and 11 mm. The diameter is between 1 and 2.6 m. The vessel have have an external insulating and fire resistant cladding. It may also have a cooling plant for cooling the LPG.
