| Abstract: | The paper analyzes the dynamic response process when the anchor penetrates the seabed based on finite element analysis program ANSYS / LS-DYNA. It analyzes the influence of different factors such as anchor weight, water depth, anchorage height and seabed sediment on the penetration of anchors in the seabed. Ultimately the best safe depth of the subsea pipelines under the effect of the anchor device is determined. |
