Initiation of revaporization of liquefied gas, e.g. methane stored in a container 1 having a lining 4, 5 of heat insulation material, e.g. balsa wood is assisted by an impervious lining 9 having a roughened surface in contact with the liquid. The balsa wood lining is initially lined with currugated aluminium foil and the corrugations below the liquid level 12 become flattened by the internal pressure to provide sharp ridges 10. In a modification crumpled foil is used as the inner lining. A paddle 13 is rotated by a motor 19 mounted on the vapour outlet duct 8. |
