| 摘 要： | 管道终端（PLET）是水下生产系统的一个重要组成部分。管道终端的支撑结构与其防沉板基础为一体，具有结构简单、安装方便、重量轻等优点。以我国南海300m水深某油田环境条件作为设计基础，根据结构整体滑动的受力特点和具体的安装方式，考虑了底流的影响，利用SACS软件对在位和吊装两种工况进行了结构分析，确定了结构形式，选用了高强钢。对防沉板基础的承载力、沉降等情况进行了计算分析，结果表明，管道终端结构和防沉板基础满足力学性能和土质要求。

| Abstract: | An oilfield in the South China Sea with water depth of 300 m is taken as the design basis of PLET（pipdine end termination） structure and foundation. The PLET structure was analyzed for in-place and lifting conditions. When high strength steel is used, the analysis indicates that all the structural members have resultant stresses well below the allowable. Due to the nature of the soil at the seabed and bottom current loadings, the foundation has been designed as mudmat structure which will accommodate settlement. The PLET structure and foundation have been incorporated to satisfy strength and bearing capacity requirements. |
