简易导管架平台结构设计及选型研究

简易导管架平台指结构型式简单、重量轻、上部设施较少的海洋油气生产平台。为了更好地进行平台结构设计选型，此文设计了一种单腿三立柱结构型式的简易导管架平台，方案一采用独立桩腿型式，方案二采用将主立柱兼作桩腿的型式，分别从静力、疲劳和倒塌三方面进行了结构设计、分析比较和选型研究。分析结果表明，方案一独立桩腿结构型式的导管架力学性能更优，为今后设计类似简易导管架平台提供参考依据。

Research on Structural Design and Selection of Minimal Jacket Platform

Minimal jacket platform refers to the offshore oil and gas production platform with simple structure, light weight and less topside facilities. In order to design and select platform structure better, a minimal jacket platform with a single-leg three-post structure type was designed in this paper. Option one uses the independent leg type, and option two uses the main column as the leg type. The structural design, comparison and selection research were carried out from three aspects: static force, fatigue and collapse analysis. The analysis results show that the mechanical performance of the jacket with independent leg type is better, which provides reference for the design of this kind of minimal platform in the future.
