Liquefied natural gas is stored in an insulated tank 4, typically forming part of an ocean going tanker. Boiled off vapour is compressed in a compressor 20 and at least partially condensed in a condenser 50. The resulting condensate is returned to the tank 4. The vapour is mixed with liquefied natural gas in a mixing chamber 32 upstream of the compressor 20. The liquefied natural gas so mixed with the vapour in the mixing chamber 32 is taken from the condensate or from the storage tank 4. <IMAGE> |
