The invention discloses an LNG cargo ship active slow swing device. The device comprises an LNG low-temperature storage tank and a base and further comprises a cabin skirt, a variable frequency motor,a gas compressor and a gas pressure damping unit, wherein the LNG low-temperature storage tank is supported on the cabin skirt and is movably connected with the cabin skirt, the cabin skirt is fixedto the base, the variable frequency motor is a power source of the gas compressor, and the gas compressor supplies gas to the gas pressure damping unit; a plurality of air pressure damping units are arranged between the LNG low-temperature storage tank and the base. According to the active slow shaking device for the LNG cargo ship, the motion accelerations, in three degrees of freedom, of heaving, rolling and pitching, borne by the wave side measurement module are converted into electric signals through the measurement module and then transmitted to the control module, and the control modulecontrols the gas compressor to output opposite acting force to act on the LNG low-temperature storage tank to achieve the purpose of active shock absorption.

    本发明公开了一种LNG货船主动缓摇装置,包括LNG低温储罐和底座,还包括舱裙、变频电机、压气机和气压阻尼单元,LNG低温储罐托放在舱裙之上,为活动连接,舱裙固定在底座上,变频电机为压气机的动力源,压气机为气压阻尼单元供气,LNG低温储罐与底座之间设若干气压阻尼单元。本发明提供的LNG货船主动缓摇装置通过测量模块将来浪侧测量模块所受升沉、横摇、纵摇三个自由度上的运动加速度转化为电信号后传输至控制模块,控制模块通过控制压气机输出相反的作用力作用于LNG低温储罐来达到主动缓震的目的。
