Abstract:The structure of gear unit support foundation on the Jack up drilling unit is complex, the inside space is very small, the plates of gear unit support foundation are relatively thick and the well seams are full penetration welded, therefore it is very difficult to complete the structures construction. In this paper, the structures 3D modeling is established with the 3D CAD software olidworks, the virtual assembly for gear unit support foundation block is completed and the animation is made to carry on the simulation analysis of the whole construction process. Through the analysis, the most optimized construction process is obtained to visually describe the whole construction process, guide site construction and to ensure the construction quality of the structure.

1 前言
升降基础结构是自升式钻井平台的关键结构,是升降装置和缩紧装置的载体,为桩腿升降提供导向,起到连接桩腿和主船体的作用。基于它的特殊用途,其板材多为高强度厚板,结构复杂,形式紧密。升降基础分段的建造是整个平台建造的难点和关键,需要根据其结构特点进行建造流程策划。由于其结构复杂,空间狭小,单纯的根据二维图纸对建造流程进行策划难度很大,而且也容易出错。另外,虽然通过CAD绘图方法能将二维再转成三维,可以直观地观察升降基础的结构特点,但由于不能进行仿真,故容易犯同样的错误。
本文以R-550D自升式钻井平台的升降基础为载体,采用简单便捷的三维建模方法对升降基础分段的各个零部件进行建模,利用其仿真功能校验初步策划的建造流程,对可行的流程进行优化,从而确定最优化的建造流程,通过三维视图等轴的形式,直观地描述整个建造流程,指导建造实施。……
