Computation of Motion and Added Wave Resistance With the Panel Free Method

Abstract

Computations have been performed to predict motions and added wave resistances for ships at forward speeds. The radiation and diffraction problems of a ship with forward speed are solved with the panelfree method in the frequency domain. In this paper, the effect of the mterms and forwardspeed/zerospeed Green functions (GFs) on the solutions are investigated using two Wigley hull ships. Computed motions, hydrodynamic coefficients, and added wave resistances were compared with the experimental data.
