多元统计分析在平台上部组块主结构重量估算中的应用

工程前期缺乏较为详细的设计基础数据,在基础数据有限的前提下,通过与已建设施实际数据形成有效的关联对比,为上部组块主结构重量的估计提供一种较为简便的方法。通过收集整理已建导管架平台历史设计数据,采用相关分析、主成分分析、回归分析等多元统计分析方法,完成导管架平台上部组块主结构钢材重量预测模型的建立,从而实现以较少数据,合理推测平台上部组块的主结构重量。

Application of Multivariate Statistical Analysis in Estimating the Weight of Main Structure of Jacket Platform Topside

In the early stage of the project, there is a lack of detailed design basic data. On the premise of limited basic data, through effective correlation and comparison with the actual data of the construction, it provides a relatively simple method for estimating the weight of the main structure of jacket platform topside. By collecting and sorting out the historical design data of the jacket platform, using multivariate statistical analysis methods such as correlation analysis, principal component analysis and regression analysis, the establishment of the steel weight prediction model of the main structure of the jacket platform topside is completed, so that the weight of main structure of jacket platform topside can be reasonably estimated with less data.
