A net zero work system for the recovery of refrigeration available from LNG during regasification is described. The system consists of a heat engine operating between an LNG heat exchanger in which regasification takes place and a sea water heat exchanger in which sea water is cooled to 246 K. A portion of the work output from the heat engine is used to drive a heat pump operating between the atmosphere and another sea water heat exchanger in which a second sea water stream is cooled to 246 K. The remaining portion of the heat engine work is used to separate fresh water from the ice-slurry. Peak fresh water output is approximately 6.7 kg water/kg LNG.
