Characterising and suppressing vortex induced vibration

涡激振动已经成为海上设备设计的限制因素，例如将石油和天然气输送到地面的柔性管道。随着石油和天然气价格的上涨，在更深的水域勘探此类资源变得更加经济，这加剧了问题。目前，由于我们目前对振动发生的时间、频率和幅度缺乏了解，因此在设计此类管道时必须采用高安全系数。这项研究将深入了解这种振动的特征，并研究抑制它们的方法。

Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibrations occur and their frequency and amplitude. This study will provide insight into the character of such vibrations and also look at means of suppressing them.
