Based on the potential theory, a code using the panel method has been devised to estimate the hydrodynamic interaction forces acting on ships in motion in confined waters, near a bank, in a canal or over a dredged channel. The approach presumes distributing a source layer on the ship’s wetted surface and also on a sufficiently large patch moving over the water boundaries in concern. The source distribution is discretized using constant-density flat quadrilateral panels. Appropriate arrangement and panelling of the moving patch constitute important part of the algorithm. The algorithm was tested by comparing numerical results and analytical results for added masses of isolated ellipsoids in unbounded water, and by comparing the numerical and analytical results for pressure distribution, surge and sway forces and the yaw moment acting on 1/8 of a uniformly moving sphere. Systematic computations of hydrodynamic interaction forces in the ship-to-boundary interaction have been carried out for a ship navigating in restricted waters with complex boundaries. Analysis of the results demonstrates applicability of the developed method to the study of the ship interaction with complex flow boundaries.
