总体设计阶段海上固定平台模块钻机结构重量计算方法研究

模块钻机的重量数据是平台设计的必要输入参数,其准确性直接影响平台的设计。结构重量作为模块钻机重量的重要组成部分,其数据计算的准确性直接影响模块钻机总体重量的准确性。模块钻机总体设计阶段不进行结构建模及校核工作,无法通过结构模型得到精确的结构重量。本文通过统计分析已有模块钻机详细设计阶段的重控文件,得出了一套适用于总体设计阶段的模块钻机结构重量计算方法,能够较为准确地算出模块钻机的结构重量,对模块钻机总体设计工作具有一定的指导意义。

The weight data of modular drilling rig(MDR)is a necessary input parameter for platform design,and its accuracy directly affects the design of platform.Structure weight as an important component of MDR's weight,the accuracy of its calculation directly affects the accuracy of the overall weight of MDR.In the overall design stage of MDR,no structural modeling and checking would be carried out,and the exact structure weight can not be obtained through the structural model.In this paper,a set of calculation methods for the structure weight of MDR suitable for the overall design stage is obtained by statistical analysis of the weight control documents of the detailed design stage of existing MDRs,which can calculate the structure weight more accurately,and has certain guiding significance for the overall design of MDRs.
