Based on SST k-棕 turbulence model, the Reynolds averaged N-S equations are adopted to analyze the ship-ship interaction effects numerically. The results show that: 1) For the ships advancing obliquely in calm water, the resistance of a ship model with another one in close proximity is increased to a certain degree compared with the single-ship sailing case and the lateral forces acted on the two-ship models point towards the fluids between the ship sides; 2) If two-ship models are advancing parallel with opposite drift angles, there is a certain difference of the hydrodynamic pressure distributions when the ship located in the up-flow and back-flow sides; 3) If two-ship models are in a stand-on course, the relative location exerts a great effect on the hydrodynamic force. The ship-ship interaction effects are remarkable for the case that the longitudinal separation between two ships is less than the ship length. At d
