A numerical computation method based on B-splines is presented for the hydrodynamic interaction forces between two ships. The B-spline functions are adopted to approximate the fully three-dimensional ship hull geometry and unknown velocity potential in the fluid domain. The results and analysis are given in detail for the hydrodynamic interaction forces between two ships moving on parallel courses. All the computations show that the numerical results are in good agreement with some experimental or other theoretical results.
