The dynamics and nonlinear wave forcing of a flexible floating structure are investigated experimentally numerically. floater was designed to match sub-harmonic rigid-body natural frequencies typical wind turbine substructures, with the addition bending mode. Experiments were carried out for three sea states phase-shifted input signals allow harmonic separation measured response. We find weakest that motion is driven by even-harmonic difference frequency forcing, linear strongest state. mode...
Abstract Empirical investigations have consistently demonstrated the multi-directional nature of actual ocean waves, a phenomenon that has been paid relatively limited attention in research field floating wind turbines. The present study seeks to reduce this knowledge gap by experimentally investigating response novel 15 MW turbine design when subjected wave conditions. experimental work was carried out deep water basin at DHI A/S (DHI), scale 1:40. In investigation, rotor simplistically...
