Accurate Predictions of Ultimate Limit State Wave Loads on Bottom Fixed Wind Turbine

Abstract

The breaking wave loads on a bottom fixed monopile foundation has been determined in this project with the aid of a Pressure Impulse Method. The pressure impulse method is the integration of pressure bounded by time within the period of a short time scale impact. A model implemented on MATLAB as an m-file was derived for an idealized wave on a cylinder with azimuth limits with relative length and impact height. Some model parameters of interest were investigated for their influence on the behavior of the structure. The pressure impulse is confined in the upper layer in both the CFD and model outcomes, which is connected to the little breaker height proportion. The model outcome depends on an attack of θmax to coordinate with the impulse pressure. The acting force increases as the azimuthal point limit increases up until π/2 where it reaches its peak.
