According to the present invention, a ship having a fluctuation pressure reduction device comprises: one or more pressure chambers maintained at a first pressure and provided in a stern; a mass member vibrating inside the pressure chamber by a deviation between the first pressure and fluctuation pressure generated by rotation of a propeller; an elastic member fixating the mass member to the pressure chamber; and a pressure pump connected with the pressure chamber and configured to adjust the first pressure.
본 발명의 변동압력 저감장치를 구비한 선박은 제1압력으로 유지되고, 선미에 형성되는 하나 이상의 압력실; 프로펠러의 회전에 의해 발생하는 변동압력과 상기 제1압력 간의 편차에 의해 상기 압력실의 내부를 진동하도록 구성된 질량 부재; 상기 질량 부재를 상기 압력실에 고정시키는 탄성 부재; 및 상기 압력실과 연결되고, 상기 제1압력을 조정하도록 구성되는 압력 펌프;를 포함한다.
