A unified "p-y+M-θ " model for laterally loaded piles considering rigidities of various piles

Yantu gongcheng xuebao
The large-diameter monopiles account for over 70% in construction of offshore wind turbines in China. The current p-y curve design method is primarily suitable for the small-diameter flexible piles.

Effect of Scour on Hydrodynamic Pressure of Offshore Monopile and Site Response Under Seismic Loads

Journal of Marine Science and Engineering
In complex marine environments, monopile foundations are subjected not only to waves and currents but also to seismic loads. The long-term combined action of waves and currents induces scour around the monopile, leading to soil loss, seabed morphology ...

Numerical Simulation and Tests of Lateral Bearing Capacity of Sloped Offshore Monopile Under Vertical Load and Lateral Cyclic Load

Journal of Marine Science and Engineering
Offshore monopile foundations endure complex loads during service. They bear vertical loads from the superstructure’s self-weight and lateral cyclic loads (e.g., wind, waves), while near-coastal seabeds are usually sloped.
