A THREE-DIMENSIONAL PANEL METHOD FOR MOTIONS AND LOADS OF SHIPS WITH FORWARD SPEED

A new three-dimensional panel method efficiently calculates motions and wave induced loads of arbitrarily shaped but slender single-hull displacement ships with forward speed in regular waves. Pulsating three-dimensional sources are distributed on the wetted hull surface. The total velocity potential is assumed to comprise a steady, speed-independent part and an oscillatory, speed-corrective part. A linear theory solves the corresponding boundary value problem on the basis of the zero-speed Green function. Numerical evaluation of surface integrals containing derivatives of the velocity potential yield hydrodynamic pressures. An additional term in the roll damping coefficient accounts for viscous resistance to roll. Results for the ITTC containership S7-175 compare favourably with measurements.
