The present invention relates to an apparatus and a method for steam jetting and freezing of an icebreaking LNG ship. In the present invention, high-temperature, high-pressure steam generated by a steam boiler is directly sprayed from the outside of a bow unit through a steam injection nozzle through a plurality of auxiliary steam pipes branched from a main steam pipe into a plurality of branches. As described above, the present invention enables a variable unit to change an injection angle of the steam injection nozzle. Accordingly, the present invention makes it possible to crush ice and forward the ice using the high-temperature, high-pressure steam. 본 발명은 스팀 보일러에 의하여 생성된 고온 고압의 스팀이 메인 스팀 파이프로부터 복수로 분기된 복수의 보조 스팀 파이프를 거쳐 스팀 분사 노즐을 통하여 선수부 외측으로부터 얼음에 직접적으로 분사되어지되, 스팀 분사 노즐의 분사 각도를 가변 유닛이 변경시킬 수 있도록 함으로써, 고온 고압의 스팀을 이용하여 얼음을 파쇄와 동시에 전진 운항하는 동작이 가능하도록 한 쇄빙 LNG 선박의 스팀분사 쇄빙 장치 및 방법에 관한 것이다.
