| 摘 要： | 考虑到集束塔式立管比单根塔式立管在总体疲劳分析时更加复杂,利用＂等效＂理论方法对集束塔式立管进行处理,建立集束塔式立管有限元模型,提出集束塔式立管总体疲劳（包括运动疲劳和VIV疲劳）的分析方法,并通过实际的案例给出相关计算结果,证明该方法是正确和合理性的。

| Abstract: | Considering that the global fatigue analysis for the bundled hybrid offset riser （BHOR） is more complex than that of the single line offset riser, the equivalent theory was introduced to deal with the BHOR. A global FE model of BHOR was established, and the analysis method of BHOR global fatigue damage （include motion fatigue and VIV fatigue） was put forward. Numerical results of a practical project proved that this method is fight and reasonable. |
