To deal with the uncertainties in modeling offshore wind turbines, we propose a parameter inversion method for pile–soil interaction model based on structural health monitoring results and numerical model. The proposed has model, an objective function selected using both identified results, inverse optimization random search algorithm assumed space. minimum are as situ parameter. is confirmed t...

As wind power technologies become maturer, the monopile foundation of offshore turbine is widely used because its simple structure, few occupied space and low cost. However, under severe sea conditions, impact nonlinear wave load applied against on system structure safety cannot be ignored. In this paper, 5MW National Renewable Energy Laboratory (NREL) was taken as research object, computationa...

Throughout their lifespan, monopile foundations supporting offshore wind turbines inevitably experience horizontal loads from waves, winds, and currents, resulting in cumulative deformation. It has been believed that deformation caused by loading weakens the interaction between pile soil, leading to a reduction ultimate uplift bearing capacity of foundation. However, there is scarcity literatur...

Abstract The growing demand for clean renewable energy sources and the lack of suitable nearshore sites are moving offshore wind industry toward developing larger turbines in deeper water locations further offshore. This is adding significant uncertainty to geotechnical design monopiles used as foundations these systems. Soil testing becomes more challenging, rigid monopile behavior less certai...
