Development of current-induced scour beneath elevated subsea pipelines

Journal of Ocean Engineering and Science, 2018
When scour occurs beneath a subsea pipeline and develops to a certain extent, the pipeline may experience vortex-induced vibrations, through which there can be a potential accumulation of fatigue damage.
