There are three different well-known methods for predicting the manoeuvrability of ships: (1) free running model test, (2) direct manoeuvring simulation using CFD and (3) system-based manoeuvring simulation. In this paper, the manoeuvrability of the KVLCC2 was estimated using CFD with rigid body motion and body force propeller method. The free running manoeuvre at the different time steps were also simulated. The yaw checking ability and the turning ability of KVLCC2 were predicted using CFD and could have been confirmed that the IMO criteria was satisfied. When the results were compared with the model test and system-based method, the free running simulation showed better agreement to that of the model test. It could also be confirmed that the results vary depending on the time step. Overall, the CFD results using the body force propeller method estimated most accurately the test results.

有三种不同的众所周知的方法来预测船舶的操纵性：(1) 自由运行模型测试，(2) 使用 CFD 的直接操纵模拟和 (3) 基于系统的操纵模拟。在本文中，KVLCC2 的机动性是使用 CFD 与刚体运动和体力螺旋桨方法估计的。还模拟了不同时间步长的自由运行机动。KVLCC2 的偏航检查能力和转向能力是使用 CFD 预测的，可以确认满足 IMO 标准。当结果与模型试验和基于系统的方法进行比较时，自由运行仿真与模型试验的结果更加吻合。还可以确认结果因时间步长而异。全面的，
