Dynamic Response of Free-Span Sub-Sea Pipelines under Vortex Induced Vibrations

Abstract:

Study of dynamic behavior of pipeline is required to access fatigue life of pipeline welds. Semi-empirical mathematical model is thus proposed to calculate responses of free-span pipelines under vortex induced vibrations. A two equation model interacted through velocity coupling with a non-linear stiffness term for pipeline model and a non-linear damping term for wake is considered. The proposed model is found to represent the real situation of responses to a greater extent.
