Numerical Modeling of Submarine Pipeline Scouring under Tropical Storms

Submarine pipelines are the lifelines of national economy. Under influence typhoons, high-speed currents and waves continuously erode seabed, leading to suspension or even rupture pipelines. Therefore, it is great importance study sediment transport under action currents. A numerical model scouring deposition combining wave established, which considered tidal current, storm surges, wind waves, sediments in East China Sea. Combining with monitoring actual laying condition pipelines, found that area most serious around KP300. It shown typhoon weather high intensity density will lead noteworthy construction marine engineering.
