深海立柱式平台概念设计研究

以上海交通大学海洋工程国家重点实验室提出的多柱桁架式立柱平台(Cell-Truss Spar)概念为例,对Spar平台的概念设计方法和过程进行了初步的研究,并对其水动力性能进行理论和数值计算,分析一些影响Spar平台运动性能的参数。设计涉及到两方面的问题:一是设计方法、流程以及结构物的形式;二是水动力性能。整个设计流程是一个不断循环的交互式的过程,需要考虑很多方面因素的影响。

Research on the concept design of Spar platform

As an offshore structure for exploitation of oil and gas in deep sea,the Spar platform has developed quickly during the last decade.This paper presents a preliminary study on the concept design method and process of the Spar platform,as well as theoretical and numerical analysis of its hydrodynamics.As an example,the Cell-Truss Spar platform concept,put forward by the State Key Laboratory of Ocean Engineering in SJTU,is brought in.Generally speaking,two aspects are involved during the concept design: one deals with the design method and structure form,and the other concerns the hydrodynamic behavior.Many effects may have to be taken into account during the design process,which can be described as an interactive flow.
