全回转起重船作业过程中船体和吊物的运动相互耦合，这会对起重船作业造成不利影响。针对起重船船体和吊物的运动特性问题，本文利用AQWA软件以1艘起重能力为12 000 t的超大型全回转起重船为对象建立水动力模型，计算该船在系泊状态下不同吊臂旋转角度、不同环境载荷入射角以及不同吊重时船体和吊物的运动响应并对计算结果进行分析，得到了船体和吊物运动随不同参数变化的规律。计算结果表明，全回转起重船船体和吊物的运动具有很强的相关性。同时对作业过程中环境条件限制和压载水调整提出建议。
The coupled movement between ship and crane load of revolving crane vessel will occur in the process of operation and effects ship performance. For the movement characteristics of ship and crane load, this paper establishes the calculation model of a super large revolving crane vessel the crane load of which is 12 000 t in AQWA software and the motion responses in different rotation angle of lifting arm, different angle of incidence of environmental load and different load weight are computed and the calculation results are analyzed and the change regulations of ship and crane load motion responses with different parameters are obtained. The calculation results show that the movement between ship and crane load are strongly relevant. And some suggestions are given for the environmental conditions limited and ballast water adjustment in lifting operation.
