摘　　要：针对3000 t全回转起重船推进器选型及推进布置设计任务,采用模块法和势流软件求解该船的风载荷、流载荷和二阶波浪力,使用规划求解法和全局变量法求解推进器推力分配模型,绘制完整和单一推进器失效模式下的定位能力曲线,结果表明,在无推进器旋转限制角的情况下,采用两种方法得到的各推进器推力的分配方案基本一致,当带有推进器旋转角时,需要采用全局变量法计算,计算结果优于Kongsberg提供的数据。In order to determine the thruster type and layout of 3000 t revolving crane vessel at preliminary design,the module method and potential flow software was used to calculate the environment loads,including wind loads,current loads and second-order wave loads.The program solver method and global variable method were selected to solve the thruster force distribution model,and the DP curves for intact and single failure condition were drawn.The results showed that the thruster force distribution scheme is nearly consistent for the two methods when there is no propeller rotation limit angle.When there is a propeller rotation angle,the global variable method is needed to calculate,as the calculation result is better than the data provided by Kongsberg.
