Abstract

Abstract: The longitudinal motion amplitude and phase for two ships with forward speed at close proximity in waves are investigated by the frequency-domain potential flow theory, which is based on the mathematical kernel of three-dimension translating-pulsating source. On the foundation of numerical validation for a modified Wigley ship, the frequency-domain method is then extended to the kinematic characteristics for two ships. The two-ship model test is focused on the surge, heave and pitch mode motions. The numerical and experimental results shows that it is applicable to solve the hydrodynamic interaction problem for two advancing ships in waves by the introduction of translating-pulsating source Green function.
