摘要
介绍一种新型多立柱Spar平台的安装扶正方法。采用准静态分析方法,设计了平台扶正前的硬舱装载方案及扶正竖立过程的软舱加载方案,并预测了平台扶正过程的运动历程。在Spar平台扶正过程中,对典型倾斜工况计算关键截面处的弯矩及剪力分布,求出最大剪力和弯矩,及其出现的截面位置和平台倾角。
This paper introduces the upending scheme of an innovative multi-spar platform.Based on quasi-static analysis method,a proposal of ballast in hard tank before upending and loading in soft tank during upending is designed and the motion of the platform is predicted.During the upending,through the calculation of the bending moment and shear distribution in critical cross-section of the platform,the maximum shear and bending moment are calculated,the position of the cross-section and inclination of the platform where the maximum shear and moment happened are found out.
