The invention discloses an offshore floating body with a movable ballast tank. The offshore floating body comprises a working deck and a lower floating body, the working deck is connected with the lower floating body through a supporting stand column; a plurality of channels are uniformly formed in the lower floating body, and ballast tanks are arranged in the channels; the ballast tank can move up and down along the channel under the action of ballast gravity; and a first limiting device is arranged on the ballast tank to limit the ballast tank from being separated from the lower floating body. According to the offshore floating body with the movable ballast tank, in the no-load state, the central buoy and the ballast tank float upwards, and buoyancy is provided by the lower floating body. During full load, the central buoy and the ballast tank sink to provide buoyancy, the overall gravity center is lowered, and the stability is guaranteed. The device is simpler in overall structure and lower in construction cost, and the working area of the upper working deck is larger.

    本发明公开了一种具备可活动压载舱的海上浮体,包括:工作甲板和下浮体;工作甲板和下浮体之间通过支撑立柱连接;所述下浮体上开均匀设有多个通道,通道内设置有压载舱;所述压载舱在压载物重力作用下能够沿所述通道上下运动;所述压载舱上设置有第一限位装置以限制压载舱脱离所述下浮体。本发明一种具备可活动压载舱的海上浮体,在空载时,中心浮筒和压载舱上浮,有下浮体提供浮力。满载时,中心浮筒和压载舱下沉提供浮力,并且降低整体重心,保证其稳定性。该装置整体结构更加简单,建造成本较低,上部工作甲板的工作面积更大。
