A New Spar Platform and Its Hydrodynamic Analysis

Abstract: 介绍了一种新型的Spar平台.由于Spar平台属柔性连接结构,允许其在一定范围内运动,故二阶漂移力为系统稳定性的控制荷载,而线形波浪力则可导致系泊系统产生疲劳破坏.为此,文中结合分析此新型平台所受水动力特性,比较其相对于现有Spar平台的优势.由于浮筒位于水下一定深度处,新型平台所受线性波浪力和二阶波浪力均大幅度减小,尤其是后者可减至现有Spar平台受力的2%左右,所以大大地改善了平台的稳定性和系泊系统的抗疲劳破坏能力.由于在上部平台和浮筒之间增加了导管架,使得各模块间的连接点大大减小,从而又方便了海上施工作业.
