Scour Protection of Underwater Pipelines
Journal of Civil Engineering and Construction, 2018 A detailed literature review on the protection of local scour beneath a submarine pipeline is presented. The review covers two basic parts of countermeasures against the pipeline scour, namely preventing the onset of scour and stimulating the self-burial of a pipeline.

Sorting of sand grains around submarine pipelines under the oblique wave
Shui kexue jinzhan, 2016 Non-equilibrium sediments transport near the submarine pipeline results in local scour, thus endangering the operation of the pipeline. To investigate the sorting of sand grains in local scour hole under regular wave action, an experimental study is ...

Journal of Marine Science and Engineering, 2020 Onshore oil and gas pipelines are often buried beneath the river bed and channel banks. One of the primary reasons for the exposure of buried pipelines is the scouring mechanism that occurs when shear stress induced on riverbed by flowing water exceeds ...

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.

Numerical investigation of wave-induced local scour around a submarine pipeline
, 2014 A two-dimensional numerical model is developed in this work to predict the local scour around subsea pipelines induced by the orbital fluid motion due to free-surface water waves. Instead of being simplified as an oscillatory flow, the motion of the wave

Local scour around two pipelines in tandem in steady current
, 2014 In this study, local scour around two identical pipelines in a tandem arrangement are investigated numerically. Two-dimensional Reynolds-averaged Navier-Stokes (RANS) equations are solved for simulating the flow around the pipelines and the conservation ...
