中文摘要：

该文结合Truss Spar平台的优点,在传统半潜式平台的底部添加垂荡板结构,通过改变垂荡板的质量、安装水深和面积,利用水动力计算软件AQWA,分别从频域和时域两方面,研究了垂荡板结构参数的变化对半潜式平台运动性能的影响。计算结果表明,垂荡板结构能有效抑制半潜式平台的运动,而且垂荡板的质量越大,安装越深,面积越大,对平台运动性能的改善效果越好。

英文摘要：

Combined on the characteristics of Truss Spar,this paper add heave plates structures in the bottom of the traditional semi-submersible platform.By changing the quality and area of heaving plate and installation of water depth,the motion performance effect of semi-submersible platform derives from heave plates structures has been investigated in both frequency and time domains by hydrodynamic calculation software AQWA.The calculation results show that heave plates structures can effectively inhibit the movement of semi-submersible platform.The bigger the quality and area of heaving plate,the deeper the installation,the better the performance of platform motion.
