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.

The paper presents the problem of liquid motion in a 2D partly filled tank. It is assumed that the flow of liquid in tank is a potential, hence it can be described by Laplace equations with appropriate boundary conditions. The problem is solved using the boundary element method. The developed numerical algorithm makes it possible to determine the free surface elevation, the velocity field and the pressure field during the liquid motion in the tank. The area occupied by liquid is represented by a mesh changing in time. Numerical computations are performed for translatory and rotational motion of the tank. The results of numerical computations are verified by experiment.
