Abstract:
A fuel storage container suitable for use in a fuel storage and delivery system for storing pressurized liquefied natural gas fuel at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123.degree. C. (-190.degree. F.) to about -62.degree. C. (-80.degree. F.) and delivering vaporized pressurized liquefied natural gas fuel on demand for combustion in an engine, wherein said fuel storage container is constructed by joining together a plurality of discrete plates of materials comprising an ultra-high strength, low alloy steel containing less than 9 wt % nickel and having a tensile strength greater than 830 MNa (120 ksi) and a DBTT lower than about -73.degree. C. (-100.degree. F.), and wherein joints between said discrete plates have adequate strength and toughness at said pressure and temperature conditions to contain said pressuized liquefied natural gas.
