摘　　要：考虑到半潜钻井平台工作在特殊的海域时需要使用动力定位和锚泊定位混合定位方式,半潜平台混合定位模式下的运动过程十分复杂,无法通过建立平台在混合定位模式下的运动方程来分析其控位能力,结合动力定位和锚泊各自的控位能力特点分析,采用先静态分析,再动态频域分析方法,得出动力定位和锚泊混合定位方式下的控位能力。The mixing of dynamic positioning and mooring would be used simultaneously for semi-submersible drilling rig under requirement. The analysis of rig movement under positioning mode of mixing dynamic positioning and mooring is complex, it is almost impossible to analyze the capability of the mixing positioning if rig. According to the positioning characteristic of dy- namic positioning and mooring, the static method was used firstly to analyze the external force of rig, and then the dynamic meth- od was used to analyze the capability of mooring. At last, the capability of mixing was obtained.
