An Influence of Trench Formation on Steel Catenary Risers Based on a Hysteretic Nonlinear Seabed Model [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2017 A steel catenary riser (SCR) attached to a floating platform at its upper end encounters fluctuations in and near its touchdown zone (TDZ), which causes the interaction with the seabed. Subsea surveys and the analysis of SCR’s indicated that the greatest

Dynamic Response of Pile at Waterwave Load and Seismic Load
Shanghai Jiaotong Daxue xuebao, 2021 The pile foundation of offshore wind turbines is not only subjected to the cyclic action of wave load, but also the threat of seismic load. Therefore, the environment of pile in the ocean is complex.
