FIELD: ground transportation of liquefied natural gas at pressure of about 1035 kPa to about 7590 kPa and temperature of -123 to -62 C. SUBSTANCE: proposed systems include at least one reservoir made by connecting many sheets from material containing super-strength low-alloy steel containing lesser than 9 wt-% of nickel at tensile strength exceeding 830 Mpa and temperature of transition from ductility to brittle failure is below -73 C; joints between separate sheets possess ultimate strength and ductility adequate for keeping the liquefied natural gas under pressure. EFFECT: enhanced efficiency and reliability. 14 cl, 4 dwg, 3 tbl, 1 ex
