In the design and analysis of deep-water platform,it is often affected by constraints of other functional or performance while adjusting a parameter to improve the platform performance. The SASEM procedure was used to build the 3D hydrodynamic finite element model of ETLP. Then the transfer functions were calculated for motion performance of ETLP by the way of utilizing potential flow theory. The influence of characteristic parameters on ETLP's hydrodynamic performance was studied on the basis of calculations. The research results are valuable for determining the characteristic parameters in the early design of ETLP.%在深水平台的设计与分析中,调整平台某种参数以提高某一性能时,经常受到其他功能或性能的约束.应用SESAM软件建立延伸式张力腿平台的三维水动力模型,采用势流理论进行计算分析,获得延伸式张力腿平台运动响应的传递函数.在此基础上研究各特征参数对平台水动力性能的影响.研究结果对延伸式张力腿平台初期设计时各特征参数的确定具有指导意义.
