... of a subsea jumper subject to vortex induced vibration (VIV) and thermal cycle is a difficult and important engineering problem. The paper focus on: State the key points of CRA clad pipe material used for the rigid jumper design, fabrication, and operation; When in areas of significant currents...

... Study of vibrations due to vortex shedding(VIV) in the wake of a cylinder that is exposed to a current is very important, especially for marine risers which are used to extract oil and gas from sea bed. The phenomenon of vortex induced vibration(VIV) has been one of the major concerns...
