摘要

An analytical investigation was carried out on the wave induced motions, with and without speed, and lateral drifting forces on two closely spaced, hydrodynamically interacting slender bodies of arbitrary geometry in oblique waves.;The lateral drifting forces were calculated using the "near-field" method which was applied to the monohull ship. Phenomena of standing wave and water shipping are also investigated in this study.;In general, the motion responses without speed effect have been in fairly good agreement with the experimental data. According to the results of study of a single ship at nonzero speed condition, the reasonability of the present analysis for two ships with speed was examined. It was found that the heading effect is significant. The results of lateral drifting force have been compared with other theoretical results.;It is found that the hydrodynamic interactions between two bodies cannot be neglected. The strip method used herein appears to be a practically useful tool to predict the behavior of two adjacent ships in seas.;The conventional strip method was used. The two-dimensional procedure proposed by Kim was employed. It considers the hydrodynamic interaction between two arbitrarily shaped cylinders freely floating in beam seas. Neglecting the surging motions we use 10 coupled equations of motion to obtain the response motions.
