提出一种利用Moses软件对FX自升式平台进行完整稳性和破舱稳性分析的方法,该方法简单实用,计算效率高。使用该方法分析平台稳性,得出如下结论:自升式平台的吃水越大,其稳性越差;FX平台完整稳性的危险风向角为15°,破舱稳性的危险风向角为120°,最危险的破舱组合为压载舱2和压载舱4。研究成果可为类似平台的稳性分析提供参考,为平台的安全拖航提供技术支持。
The article proposes a method to analyze intact stability and damage stability of the FXjack-up platform by using Moses. The practical method has high computation efficiency. Through analyzing the stability of platform by Moses, it concludes that the stability of jack-up platform becomes worse with bigger draft. For the intact stability, the dangerous angel of wind is 15~. For the damaged stability, it is 120~. The most dangerous damaged multi-compartments are compartment 2 and 4. The article can provide reference for the stability analysis of platform and technical support for safe towage.
