As a non-negligible problem, the suppression of sloshing is very important for liquid storage carriers such as LNG (Liquefied Natural Gas) ships. The effective suppression of impact pressure caused by sloshing liquid improves the safety of the structure. In this paper, the porosity characteristic is combined with the adjustable hanging part, and the effects of this composite anti-sloshing method on sloshing states are studied by CFD (Computational Fluid Dynamics). The results show that, compared with the traditional solid part, the composite method with appropriate porosity can further suppress the sloshing, and the load acting on the hanging porous part induced by the sloshing liquid is smaller. When the porous part near the static free surface moves downward, the damping effect enhances, leading to further improvement of the anti-sloshing effect, but the load acting on the part increases.
