To study the stability of the sail-assisted ship in the wave, taking a 46 000 t tanker as the target ship, firstly, according to the data of the target ship, the ship 3D modeling was established by using Maxsurf software and its correctness was verified. Secondly, the relative position of ship and wave was divided into 4 cases to analyze the stability of the sail-assisted ship in different ship-wave positions. Results show that when the peak is located in the middle and the wavelength is approximately equal to the ship’s length, the ship’s stability decreases greatly. Finally, the random number was selected by Matlab software to simulate the random waves in the course of ship sailing, and the safety and reliability of the ship with wind wings were calculated. According to the most dangerous situation such as ship sailing at 8 level, the safety of the ship with sail-assisted is lower than that without wing, and the capsizing probability is about 4.77%.
Key words： sail-assisted ship; stability; capsizing probability
