新型S-Spar概念設(shè)計及時域動力響應(yīng)分析(英文)
發(fā)布時間:2021-03-16 11:26
本文概念性地提出了新型Spar平臺S-Spar用于深水和超深水海洋油氣開發(fā)。S-Spar連接軟艙和硬艙的是和中央井同尺寸的圓形立柱。有別于傳統(tǒng)的經(jīng)典Spar和Truss Spar,S-Spar有一個細長的中間段,垂蕩板安裝在中間段增加垂蕩阻尼的同時,封閉的中段可以保護立管免受波流荷載。文中介紹了S-Spar的基本概念,進行了頻域和時域耦合動力響應(yīng)分析,并進行了S-Spar連接的頂張式立管的動力響應(yīng)和VIV疲勞分析,將計算結(jié)果和Truss Spar的計算結(jié)果相比較,結(jié)果顯示新型S-Spar能改善平臺的水動力性能,同時封閉的中央井對立管起到很好的保護作用。
