Abstract
LNG from a carrier is unloaded to an LNG storage tank in configurations and methods in which expansion of compressed and condensed boil-off vapors from the LNG storage tank provide refrigeration to subcool the LNG that is being unloaded. Most advantageously, such configuration and methods reduce the amount of boil-off vapors and eliminate the need for a vapor return line and associated compressor.
