The impact of sloshing effects due to inner liquid cargo has long been recognized as a crucial parameter in the design stage, spanning decades. Numerous research and engineering literatures have emphasized how these effects can alter the motions of floating bodies, including their natural frequencies. The recognition of sloshing effects has prompted investigations into utilizing them positively, leading to initiatives like the development of anti-rolling tanks. This study delves into the exploration of anti-rolling tanks using the Moving Particle Semi-Implicit (MPS) method. The effects of these tanks on vessel motions are considered through a dynamically coupled problem employing the Boundary Element Method (BEM). The sloshing effects on vessel motions are demonstrated, and their positive implications, such as motion control and manipulation of the vessel's natural frequency, are thoroughly examined. The findings reveal that the natural phenomena of the vessel can be effectively controlled by adjusting sloshing reduction effects. This not only highlights the significance of considering sloshing effects in vessel design but also underscores the potential for utilizing them to actively control and manage vessel motions for improved performance and stability.
