摘要
导管架滑移下水是安装重型导管架的一种常见的方式 ,2 0世纪 70年代初国外已开始在海上实施导管架的滑移下水 ,80年代初 ,有关导管架滑移下水的数值模拟分析和安装技术已趋于成熟。随着我国对海上深水油田的进一步开发 ,吸收国外的先进经验 ,掌握这方面的分析技术并使之应用于我国深水开发工程尤为紧迫。在参阅OTC论文、国外的相关出版物和规范的基础上 ,对导管架滑移下水过程的分析方法和设计方法进行了论述 ,并结合一个工程算例进行了分析 ,算例中使用的软件为MOSES。
Launch is a common operation for heavy jacket. Early launch jacket was installed in the dearly 1970's. Some powerful computer programs for jacket launch simulation were developed in the 1980's with development of the offshore oil and gas field in deep water. Now it is necessary to apply the latest experience of jacket launch form abroad in China Sea. By the reference of OTC papers, the paper describes the launch simulation analysis methodology and design method, with an engineering example. The computer program for jacket installation simulation, MODES is used in the launch analysis.
