柱稳式半潜钻井平台稳性分析

Stability Analysis of Column Stabilized Semi-Submersible Unit

对一艘双钻塔半潜式钻井平台进行稳性分析,建立三维计算模型,根据平台布置进行风载计算和选取进水点,分别对平台的各作业吃水进行完整及破损稳性分析获取平台的极限重心高度曲线,对比设计作业工况证实平台的稳性满足要求。

The paper analyzes the stability of a column stabilized semi-submersible unit. The 3D computing model is established According to the unit arrangement, the wind load computation is done and the inlet point is selected The intact and damage stability analysis for different operation drafts of the unit is done to gain the AVCG curves of the unit, which is compared with the design operation condition. The result verifies that the stability of the unit meets the requirements of class regulations.
