Abstract

Abstract: An analytical study is performed to evaluate the displacement behavior of monopile of offshore wind turbine founded in sandy soil. The system consists of pile, turbine tower and soil modeled as 3D finite element model in ANSYS. An explicit dynamic analysis is performed in a time domain considering soil as an explicit material and wind and wave loads act on the turbine tower as static loads. Behavior of monopile in soil is analyzed by considering soil pile interaction. The study shows that pile displacement and pile tilt angle depends on soil properties and pile embedded length and pile diameter.
