Numerical techniques for the prediction of wave effects have achieved an important role in offshore engineering, comparable to physical experiments. For large structures it is appropriate in most cases to use the linear (or weakly nonlinear) potential theory. This permits us to consider structures of quite general geometrical form, for a broad variety of applications. We restrict our attention here to fixed structures and vessels that are free to move in small unsteady motions. Thus we exclude the seakeeping problem for ships that are underway with substantial forward velocity. The panel method, also known as the boundary integral equation method (BIEM), has been widely used for this purpose. The fundamental basis for this method is a form of Green’s theorem where the velocity potential at any point in the fluid is represented by surface distributions of singularities over the boundary surfaces [1]−[4]. Generally, this leads to an integral equation that must be solved for the unknown source strength or dipole moment. This procedure was mainly of theoretical interest until Hess and Smith
