【Abstract】 vortex induced vibration on span is an important factor which result in the submarine pipeline failure.Considering the fuzzy character of both span vibration character and hydrodynamic load,this paper presents a fuzzy complicate assessment model of span fuzzy reliability,which under the action of vortex induced vibration,basis on fuzzy theory,system analysis theory,offshore engineering theory,and reliability theory.更多还原
