新型S-Spar概念设计及时域动力响应分析(英文)
发布时间:2021-03-16 11:26
本文概念性地提出了新型Spar平台S-Spar用于深水和超深水海洋油气开发。S-Spar连接软舱和硬舱的是和中央井同尺寸的圆形立柱。有别于传统的经典Spar和Truss Spar,S-Spar有一个细长的中间段,垂荡板安装在中间段增加垂荡阻尼的同时,封闭的中段可以保护立管免受波流荷载。文中介绍了S-Spar的基本概念,进行了频域和时域耦合动力响应分析,并进行了S-Spar连接的顶张式立管的动力响应和VIV疲劳分析,将计算结果和Truss Spar的计算结果相比较,结果显示新型S-Spar能改善平台的水动力性能,同时封闭的中央井对立管起到很好的保护作用。
