A sloshing preventing device (20) with an easy or simple structure or configuration prevents a sloshing phenomenon from occurring in a membrane liquid storage tank (10) of a liquid cargo carrier or floating marine installation (1). The sloshing preventing device has a plurality of floating bodies (24) which are serially arranged in the longitudinal direction or the lateral direction of the carrier or the marine installation, and vertical struts (23) which support the floating bodies against horizontal external force acting on the floating bodies, and guide the floating bodies in the vertical direction. The floating bodies each have the weight for securing the proper draft depth (D). Each floating body floats on a free liquid level (LL) in the tank to divide liquid on the liquid level and around the liquid level, and shifts the natural frequency of liquid vibration to a side of a high frequency zone. |
