The study analytically investigates wave‑induced motions of two closely spaced slender ships advancing in oblique waves. The authors employ a two‑dimensional strip‑method integral equation approach that incorporates hydrodynamic interaction to model the coupled motions. Numerical results demonstrate that hydrodynamic coupling is crucial, reducing rolling during advancement and confirming the strip method’s effectiveness for predicting the coupled motions of two ships in oblique seas.
An analytical investigation is carried out on the wave-induced motions on two closely spaced, hydrodynamically interacting slender bodies advancing in oblique waves. The two-dimensional procedure, including the hydrodynamic interaction and an integral equation method, is utilized. Numerical results are presented for the coupled motions of two ships. Comparisons are made with the behavior of a monohull and the interaction effect is found to be very important. Different headings and speeds are investigated. It has been found that the rolling motion is reduced while the ships are advancing—a helpful circumstance for cargo transfer between two ships. This study shows that the strip method is a useful technique to predict the hydrodynamically coupled motions between two ships advancing in oblique seas.
