考虑到自升式结构物站立状态下可能发生倾覆，对风车安装船在自存和作业设计工况下的抗倾覆稳定性进行校核。应用Genie软件建立整船结构模型和完成重量分布，通过Wajac软件计算风浪流载荷的倾覆力矩，以及手算完成稳定性力矩，并考虑动态放大效应与P-delta效应，与安全系数对比完成该风车安装船抗倾覆稳定性的评估，基于评估结果分析自升式结构物抗倾覆稳定性的影响因素和设计方面的考虑。
攷慮到自升式結構物站立狀態下可能髮生傾覆，對風車安裝船在自存和作業設計工況下的抗傾覆穩定性進行校覈。應用Genie軟件建立整船結構模型和完成重量分佈，通過Wajac軟件計算風浪流載荷的傾覆力矩，以及手算完成穩定性力矩，併攷慮動態放大效應與P-delta效應，與安全繫數對比完成該風車安裝船抗傾覆穩定性的評估，基于評估結果分析自升式結構物抗傾覆穩定性的影響因素和設計方麵的攷慮。

Considering the probability of overturning for Jack-ups in elevated conditions, the overturning stability is assessed for the jack-up wind turbine installation vessel.The global FE model and weight distribution are performed by Genie and the over-turning moment by wind, wave and current is calculated by Wajac.The stabilizing moment is derived by hand calculation.The dynamic amplification and P-delta effects are considered.The overturning stability assessment is completed by comparing safety factor with the requirement and relevant factors of overturning stability and effects to the Jack ups design are analyzed based on assessment results.
