<p>A system for gas supply to dual- fuel or gas engines and BOG reliquefaction, the BOG reliquefaction plant comprising a cryogenic heat exchanger (1), a BOG compressor (2) having a BOG preheater (3), and a nitrogen loop with a compander (4), gas feeding the engines is in the form of LNG from at least one cargo tank (5) and/or condensate from the reliquefaction plant, and the LNG and/or condensate being passed through an LNG evaporator (6) arranged in a closed loop having at least one pump (7) and a heating source (8) for an intermediate medium circulating in the closed loop as to provide for cold duty extraction when producing gas fed into the engines. Further, according to the present invention a LNG optimizer (9) is arranged in front of the LNG evaporator (6) enabling heat exchange by means of available warm and cold duty in the BOG reliquefaction plant and LNG or condensate to be fed as gas into the engines, respectively.</p> |
