纯横移运动是一种特殊的操纵性指标，它可以判断船舶主推进器和侧推器的配合能否抵御环境影响。好的横移能力能降低船舶进出港口的时间，提高船舶停靠码头的作业效率。船厂需要在设计初期通过此指标判断和选定满足要求的侧推器功率。本文基于MMG建模方法建立风载荷下客滚船的纯横移运动数学模型，采用各推进器推力的百分比之和最大的方式进行推力配比，并依据测量高度对风速进行修正。与文献中的某客滚船的模型试验结果的对比验证较为吻合，证明了计算的有效性。最后对3艘客滚船进行了验证和预报，给出了合同设计阶段需满足纯横移运动指标的侧推器功率。
Crabbing is special ship maneuvering characteristics, it can determine whether a combination of main propellers and lateral thrusters resist environmental forces. A good crabbing ability can effectively reduce harbor time for ship and improve port operation efficiency. Ship yards need to estimate the power of thrusters at preliminary design stage. In this paper, crabbing mathematical model of ropax considering wind load based on MMG model is provided, the thrust allocation is determined by the maximum value of the sum of the percent thrust of each propeller and thruster, wind speed is modified based on measuring height. The calculation results and the model test results of a ropax in the literature are compared and verified to be consistent，proved to be validity. At last, three ropax are predicted, the power of thrusters based on crabbing ability in contract design stage is provided.
