Liquid cargo moving in holds (sloshing) of a ship sailing in waves affects ship motion. Sloshing forces are taken into account in the equations of ship motion. The motion of liquid cargo in ship holds is described by boundary value problems in which the essential element is the moving free surface of the liquid. This problem is solved by Boundary Element Method. This paper presents the analysis of ship motion effected by moving molten sulphur in partly filled holds. The analysis has been carried out for different regular and irregular waves inducing ship motion coupled with sloshing. A numerical solution of the sloshing boundary-value problem and the equations of ship motion make it possible to develop a visualization of the ship motion in waves.
