基于OFFPIPE的海底管道S型铺设计算机辅助优化设计技术

Computer Aided Optimization Technology Based on OFFPIPE for Offshore Pipeline S-Lay Design

OFFPIPE是海底管道铺设设计中广泛使用的功能强大的铺管分析软件,但是,该软件也存在对托管架建模不够精确、手动操作过程较繁琐以及输出结果难于被数据处理软件读取等缺点。文章论述了采用Delphi开发了一套针对OFFPIPE的辅助优化设计软件,具有对托管架精细建模、OFFPIPE外部程序自动控制、OFFPIPE输出文件读取等技术特点,使繁琐的人工设计调整过程完全自动化。该软件大大提高了OFFPIPE的使用便捷性和效率,在海底管道铺设设计领域有很高的应用价值。

Software OFFPIPE is a powerful FEM based computer program which has been widely used in offshore pipelaying design.However,several disadvantages still exist in this software,for example,stinger modeling is not precise enough,output files are difficult to read by data-processing software and manual operations are tedious and numerous.This paper develops the design optimization software with software Delphi to provide aid to OFFPIPE,which possesses some new functions,such as precise stinger modeling,OFFPIPE automatically controled by external software and automatic OFFPIPE output file reading.Thus,the whole design procedure can be automatically completed with the aid of this software.By the method described in this paper,the application convenience and efficiency of OFFPIPE increase greatly,which has a significant value in offshore pipelaying design area.
