以一座预想在我国南海作业、工作水深3 000 m的深水半潜式钻井平台为例,应用MOSES程序对该平台的运动性能和锚泊定位能力进行了系统的分析.首先建立平台的三维湿表面模型,采用三维绕射辐射理论进行计算,获得了作用在平台湿表面上的波浪载荷和平台响应的传递函数.结合南海海况资料,对平台运动响应进行了短期预报.然后采用时域耦合分析法对该平台锚泊系统的定位能力进行了计算.研究结果对该平台的模型试验具有参考意义.

This paper analyzes the motion performance and mooring system of deepwater semi-submersible drilling unit in the district of the South China Sea using the MOSES procedure system. After the 3-D panel model of the unit was built, the 3-D diffraction-radiation theory was used to obtain the hydrodynamic loads on the wet surfaces and the response amplitude operators (RAO) of the unit. According to the environmental data, the short-term motion response to motion performance of the unit is predicted by the spectral method. Then a time-domain calculation was done to analyze the motion of the unit with its mooring system. The research results can be a reference for the model test of unit.
