Assumed that the coherence of the wind load in vertical is the same to the wind speed, the auto power spectrum and cross power spectrum of the wind load on the tower is formulated. Futhermore, the analysis shows that the contribution of the turbulence is about equal to the vortex shedding for the cross-wind motivation.

With the appearance of a free span pipeline, its loading types and stress state will be changed. Especially when ocean currents pass through it, a periodical vortex shedding is often produced and induces vibration of the free span pipeline. This type of vibration contributes a lot to the fatigue failure of a free span pipeline.
管跨段的出现改变了海底管线所承受的载荷形式和应力状态,尤其是在海流作用下流经管跨时,常伴随着周期性的涡旋发放,引发管跨段的周期性振动,成为管跨段发生疲劳失效的主要因素之一。
