Open publisher page 0 citations

Abstract

Ships hydroelasticity theory is employed to predict the wave induced dynamic response of a hull. There are propeller forces on the stern and slamming forces on the bow which must also be considered. In this paper, the Hamiltonian method is proposed to solve this problem. Results are presented for a 35 000 ton ship under wave and propeller excitation.
