摘要
在深水平台的设计与分析中,调整某一结构参数提高某一性能的同时,常常受到其他功能或性能上的约束,因此引起了平台各项功能及性能之间的相互竞争。以一种创新的深吃水多立柱平台(Deep Draft Multi-Spar)为目标,探讨平台结构特征参数如立柱直径、立柱高度、立柱间距和压载舱位置与平台稳定性能、水动力及运动性能、结构要求和功能要求之间的关系。水动力分析和响应计算结果显示,随着DDMS平台吃水深度的降低,垂荡、纵摇和纵荡RAOs均逐渐增大,运动性能降低,并与典型的Spar和半潜平台的RAOs进行了比较。
In the course of design and analysis of deepwater platform,it is restricted by other functions or capabilities when one parameter is adjusted to improve one performance.As a result,some competitions are induced between the functions and capabilities of the platform.Based on an innovative Deep Draft Multi-spar,the relationships of the platform′s structural characteristic parameters and stability performance,structural requirement,functional requirement,hydrodynamic and motion performance are discussed.The objective structural parameters involve column diameter,column height,distance of columns and location of ballast tank,etc.The results of hydrodynamic analysis and motion calculation indicate that the heave,pitch and surge RAOs of DDMS platform increase with the decrease of the draft height.In addition,the RAOs of DDMS platform are compared with those of the typical Spar and Semi platform′s RAOs.
