Abstract: The numerical model of the hydrodynamic interaction of bodies (ships in particular), that move in ideal incompressible fluid, has been built. The model is based on the three-dimensional boundary element method, in accordance with which the surface of a body and impenetrable areas of the boundary are approximated by the system of triangular elements. The interaction of the ship with a rectangular (vertical) bulge near a vertical wall in shallow water in the conditions of current is considered. It is shown, that the forces of hydrodynamic interaction substantially differ depending on the size of a bulge and the shape of a ship. Even small current, both in opposing and in the same direction can cause considerable change of the hydrodynamic forces.
