摘要
合理地设计半潜式平台结构,使它具有所期望的优异性能和安全性,需要有能分析计算平台的运动响应、结构响应及其统计预报的程序系统。本文介绍的“OSAS—3”程序系统就是具有这些功能的系统,它不仅能计算平台的运动响应、结构响应和预报分析,而且还能进行定常外力计算和设计波法的结构强度校核计算。文中介绍了计算机程序系统、特征和理论计算方法的概要。这个程序系统和国外主要船级社的同类系统具有同样的基本计算功能,经与国外同类程序比较,其相应的计算结果吻合得很好。
To design semi-submersible structures which have intended excellent performances and safety behavior, it is indispensable to develop the program system that can be applied to the analysis of motion responses, structural responses and statistical predictions for the semi-submersibles. This paper presents a computer program system OSAS-3, which can be used for above purposes, e.g. motion and structural response analyses,statistical predictions for the semi-submersible platform, and also for calculating stationary external forces in still water condition and strength check for structures with design wave methods.This program system has the same main functions as similar programs of classificatiori societies abroad. Coincidence between the calculation results of this program and those of the other foreign similar programs is quite good.
