An appropriate fuel storage container is used in a fuel storage and feed system designed to store pressurized liquefied natural gas (LNGP) at a pressure between 1 035 kPa (150 psia) and 7 590 kPa (1 100 psia) [105 465 - 773 410 kg / m2, absolute pressure] and at a temperature from - 123 ° C (-15 ° F) to - 62 ° C (-80 ° F) and to feed vaporized GNLP fuel in the quantity required for combustion in a engine, wherein said fuel storage vessel is constructed of materials comprising a low alloy steel and ultra-high strength that contains less than 9% nickel and has a tensile strength greater than 830 MPa (120 ksi [84 372,000 kg / m2]), and a transition temperature from ductile to fragile -DBTT - below -73 ° C (-100 ° F). |
