THREE-DIMENSIONAL INTEGRAL-EQUATION METHOD FOR CALCULATING THE EFFECTS OF TANK-WALL INTERFERENCE ON HYDRODYNAMIC FORCES ACTING ON A SHIP

A three-dimensional integral-equation method is developed for predicting the hydrodynamic forces acting upon a ship and the resulting motions of the ship. The effects of tank-wall interference are included. The proposed calculation method is restricted to the zero-speed problem, but in principle provides an exact solution for a body of arbitrary geometry. The integral equations for the radiation and diffraction velocity potentials on the body surface are derived by applying Green's Theorem. They are solved numerically through a discretization of the body in panels, with the velocity potential assumed constant in each panel. The Green function satisfying the tank-wall boundary condition is provided by first considering an infinite number of mirror images and then obtaining a closed-form expression for the resultant infinite series.
