Abstract:

The paper firstly brought forward hierarchical division based on process flow, and constituted layout theory, arithmetic, and layout process. The method was based on operational flow, and different transportation modes were marked out according to the shape and quality to material modality. The sub-space were decomposed into basic layout units. We applied reasonable layout algorithm to mark out the different decks. The storage mode of column and pontoon was projected. Finally the center of gravity was taken into consideration and the general layout was adjusted according to result in an optimal center of gravity.According to the layout programming, we took a project in the scantling design as an example,the layout of rigs system was implemented in details.

Key words: semi-submersible drilling platform, general layout, drilling operation flow, optimization of three-dimensional layout, group technology

摘要：

基于作业流程层次分解布局法，提出了布局理论、算法和布局流程。该方法以作业流程为基础，按材料输送系统输送模式划分子空间，子空间以模块为布局基本单位，对不同空间采用相应优化算法，并对立柱和下浮体的存储区进行规划，然后根据重心对平台布局进行调整，以提高稳定性，完成布局的详细设计。以在建某平台为实例，提出了布局方案，完成了布局设计。
