Negative factors in ensuring the safe operation of liquefied natural gas reservoirs are identified, which manifest themselves during liquefaction, unloading, receiving and regasification of the product. The role of heat losses in ensuring the safe operation of tanks is shown. Methods are analyzed in terms of considering possible variable thermal effects on the outer surface of a tank with liquefied natural gas. A method for thermal calculation of an isothermal tank is presented, which makes it possible to consider the thermal inertia of multilayer insulation when exposed to thermal radiation from a fire of variable intensity.
