Numerical Simulation of Seabed Response Around Monopile Under Wave–Vibration

Journal of Marine Science and Engineering
Monopile foundation is an important foundation form for offshore wind turbines, and the stability of the seabed around it is affected by the combined effects of wave and pile vibration.

Wave (Current)-Induced Pore Pressure in Offshore Deposits: A Coupled Finite Element Model

Journal of Marine Science and Engineering, 2018
The interaction between wave and offshore deposits is of great importance for the foundation design of marine installations. However, most previous investigations have been limited to connecting separated wave and seabed sub-models with an individual ...

Three-Dimensional Analysis of Momentary Liquefaction near Submarine Pipelines [PDF]

, 2007
Wave-induced seabed liquefaction and shear failure have been identified as important mechanisms of submarine buried pipelines failure. Most previous studies evaluated the potential of seabed instability around underwater pipelines using two-dimensional ...

Quantification of rheological parameters in deep‐sea mining plumes

Deep Underground Science and Engineering, EarlyView.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Observations of Backscatter from Sand and Gravel Seafloors Between 170-250 kHz [PDF]

, 2015
Interpreting observations of frequency-dependence in backscatter from the seafloor offers many challenges, either because multiple frequencies are used for different observations that will later be merged or simply because seafloor scattering models are ...
