A review on vibrations of marine pipelines
- Technical Univ. of Denmark, Lyngby (Denmark)
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.
