FIELD: transport.
SUBSTANCE: invention relates to sea transportation of liquefied gas with boiling temperature of -48°C. To produce fuel as liquefied natural gas for ship (1, 6) first liquefied gas is used. At least one tank (2, 7) is used for second liquefied gas. First liquefied gas features lower boiling temperature than the first one. Heat for evaporation and/or heating of first liquefied gas is partially bled from cargo tank content, Portion of heat is obtained via heat exchange with evaporations of cargo tank content and condensation of said evaporations.
EFFECT: safe use of the ship, reduced number of cooling modules for re-liquefaction, pipelines and electric cables, electric power saving.
