This paper presents the effectiveness of a sloshing suppression bulkhead which divides the cylindrical or co-axial cylindrical vessel vertically into several sectors. The sloshing mode is separated into two modes by the bulkhead; one is the sloshing mode of the water column in a U tube, and the other is the sloshing mode in the sector tank. The motion of equation for sloshing in the divided cylindrical vessel is derived from Lagrange's equation. Two sloshing mode are shown by the equations to be decoupled from each other. The vertical bulkheads have the effect of decreasing the participation factor of the U-tube-shaped sloshing mode. The calculated results yielded by the equation for a model vessel and an actual size vessel are compared with the numerical results obtained by the CFD code and model tank test. It is clarified that the vertical bulkheads are effective in suppressing sloshing.
