Abstract: Liquefied hydrocarbon gas carried by a tanker (78) is transferred to an import terminal (10) where the liquefied gas is heated to vaporize it and to heat the cold gas to at least ?30° C. but preferably about 0° C., with the warmed gas transferred to a gas receiving facility (20, 83). Vaporizing and heating is accomplished by using a large number (more than 10) of vertically mounted air vaporizers (84) of a known type, which use environmental air that flows down the exterior of the finned tubes in which the liquefied or cold gas flows. In the present invention a large number of individual vaporizers are positioned in close proximity to each other, i.e. within a distance that is smaller than half the vertical height of the vaporizer tubes. Their close proximity allows many units to be installed on a small plot space, and also affects their thermal performance.

Abstract: Liquefied hydrocarbon gas is carried in a tanker (12) to an offshore location where the liquefied gas is to be transferred to an offloading facility (20) such as a barge (21). At the offshore location the liquefied gas is to be heated to change it into a gaseous state and to heat the cold gas to produce warmed gas of at least about 0° C., with the warmed gas transferred to a storage facility (32, 33). Heating is accomplished without using only sea water and the burning of gas, by using air blowers (36, 38, 52) that blow large amounts of environmental air past containment structures (14, 28, 32, 42, 44) such as tanks, pipes and heat exchangers thermally coupled to the tanks and pipes, in which the liquefied or cold gas lies.
