NOVELTY - The arrangement (1) has cylindrical single tanks (2) i.e. cryo tanks, elongated in a longitudinal direction (L) and including an outer casing (4) and a circular cross-sectional surface (6) with a center point (7). The single tanks are connected with a cooling area of a refrigerated lorry over connection lines. The single tanks are tightly arranged next to each other and filled with low-cold liquefied gas e.g. low-cold liquefied nitrogen, low-cold liquefied oxygen and/or low-cold liquefied carbon dioxide. A heat bridge is arranged between the tanks to transfer heat between the tanks.    USE - Tank arrangement for storing and/or transporting low cold liquefied gas e.g. low cold liquefied nitrogen, low cold liquefied natural gas, low cold liquefied oxygen and/or low cold liquefied carbon dioxide, in a single tank for cooling and operating an internal combustion engine of a refrigerated lorry (all claimed).    ADVANTAGE - The single tanks are tightly arranged next to each other and filled with low-cold liquefied gas, thus enabling storage and transportation of the gas under high pressure according to requirement and in a flexible, economical, space-saving manner without changing the tank construction in variable volume ratios. The arrangement is applicable in a versatile manner. The design of the tank arrangement reduces the need of additional insulation material for external thermal insulation of the tank arrangement, increases mechanical stability of the arrangement, avoids installation of additional back stays, and reduces material consumption and weight of the arrangement. The nitrogen is utilized to avoid vaporization of liquefied natural gas. The provision of the connection lines achieves practicability of a filling process of the gas in daily use of the tank arrangement.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for storing and/or transporting low cold liquefied gases in a tank arrangement.
