摘要
作为海洋油气资源开发的基础性设施,海洋平台的安全特性越来越受到人们的重视。本文以某自升式平台为研究对象,基于大型有限元分析软件ANSYS软件平台,分别采用ANSYS的静力分析、模态分析研究了平台在风、流和波浪联合载荷作用下的受力特点,获得了平台的模态振动规律。分析结果显示,该平台具有较好的抗风、抗波浪力能力,但应避免平台的低频振动,而且平台桩腿始终是其较为薄弱的构件。
The safety analysis of offshore platform is more and more important, because the offshore platform is the basic establishment for marine oil and gas exploitation. Certain jack-up platform is the study object, and the ANSYS software is the study base. The mechanical character of the offshore platform suffering from wind, current and wave force was researched by virtue of ANSYS static analysis module. The vibration law of offshore platform was obtained by means of modal analysis module. The research results show that, this platform has good ability to resist wind and wave force. However, the low-frequency vibration of the platform should be avoided. What＇s more, the spud legs are always infirm.
