Stability design of submarine pipelines is a very important procedure in submarine pipeline engineering design.The calculation of hydrodynamic forces caused by waves and currents acting on marine pipelines is an essential step in pipeline design for stability.The hydrodynamic forces-induced instabilities of submarine pipelines should be regarded as a wave/current-pipeline-seabed interaction problem.This paper presents a review on hydrodynamic forces and stability research of submarine pipelines under waves and currents.The representative progress including the improved design method and guideline has been made for the marine pipelines engineering design through experimental investigations,numerical simulations and analytical models.Finally,further studies on this issue are suggested.
