Abstract

Motivated by the importance of slow-speed underway replenishment of vessels in offshore shipping, this study aims to investigate the interaction and wave resistance phenomena between two ships sailing in close proximity, which may lead to lateral drift, yaw, and even collision, posing a great threat to the safety of both vessels. KVLCC2 and Aframax standard model ships were chosen as the research objects. To examine the ship-ship interaction and wave resistance phenomena in regular waves under the conditions of low-speed single ship and staggered navigation, RANS numerical simulation method and overset grid technique were employed. The simulation results indicate that the ship's motion and forces and moments between two ships are sensitive to the wave's wavelength, especially in the range of λ/Lpp=1~1.5, where response peaks were observed. Compared to single-ship navigation, the longitudinal pitching effect of two ships sailing staggered in waves is significant and increases with wave height. This study provides an important reference value for the safe navigation of ships during wave-induced staggered navigation and replenishment operations at sea.
