当管道未埋设时，大多数位置可能存在无支撑的管道跨度。当由于冲刷而形成跨度时，它们可能会不时改变位置，而在管道交叉或海底不平坦（海床不可侵蚀）的情况下，位置是固定的。 Orgill 等人表示，跨度长度可能是管道直径的 10 到 100 倍，与海底的间隙可能在几乎为零到管道直径的 2 倍甚至 3 倍的范围内。 （1992）。当受到流动作用时，这样的管道跨度可能会经历流动引起的振动。对海洋管道的振动进行了全面的审查。审查分为四个主要部分，即稳定电流中无壁圆柱体的振动、波浪中无壁圆柱体的振动、靠近海床的影响以及最后力对振动管道的影响。
When pipelines are not buried, unsupported pipeline spans may exist in most locations. When spans develop due to scour they may change location from time to time, while in the case of pipeline crossings or seabed unevenness (where the bed is non-erodible), the locations are fixed. The span length may vary from 10 to 100 times the pipeline diameter, with a clearance from the sea bottom which may be in the range from practically nil to 2 or even 3 times the pipeline diameter, Orgill et al. (1992). Such a pipeline span, when exposed to flow action, may undergo flow-induced vibrations. A comprehensive review is presented of vibrations of marine pipelines. The review is organized in four main sections, namely vibrations of wall-free cylinders in steady current, vibrations of wall-free cylinders in waves, the influence of he close proximity of the seabed and finally forces on a vibrating pipeline.
