A system and apparatus for condensing boil-off vapor from a Liquified Natural Gas (LNG) container are disclosed. A system for condensing vapor includes the steps of providing contact area (56) within a condenser vessel (10), directing vapor (28) to the condenser vessel (10), providing a condensing fluid (66) and a pump fluid (72), directing the condensing fluid (66) to the condenser vessel (10), varying the flow of the condensing fluid (66) to control the pressure in the vessel (10), contacting the vapor (28) with the condensing fluid (66) to create a condensate, and combining the condensate and the pump fluid (72). An apparatus for condensing vapor includes a vessel (10), a liquified gas input (64) to the vessel, control means (114, 128) on the liquified gas input (64) for varying a first liquified gas stream (66) to control the pressure in the vessel, a vapor input (76) to the vessel, means for condensing vapor in the vessel, and means for combining condensed vapor with a second liquified gas stream (72).
