Abstract

The ultra large-scale development of floating offshore wind turbines （FOWTs） enables them to generate greater motion under smaller environmental loads. Based on this, a novel 15 MW FOWT multi-column with reduced diameter semi-submersible foundation （MRD） suitable for deep sea applications is proposed. Conduct frequency-domain hydrodynamic calculations based on AQWA, and establish a fully-coupled numerical model with open FAST for time-domain simulation analysis. Assess its performance in comparison to with the UMaine VolturnUS-S （UMaine） reference foundation under rated wind conditions. The free decay test proves that the MRD foundation moderates the natural frequencies in the heave and pitch directions, and minimizes the risk of structural resonance. The frequency-domain analysis indicates that the wave excitation in the heave direction of MRD decreases, while the additional mass and radiation damping in the heave and pitch directions increase, and the RAOs in the surge, heave, and pitch directions shrink. The results of fully-coupled time-domain analysis show that MRD has better surge and heave oscillations than that of UMaine, and the maximum output power rises. The research results can provide theoretical reference for the conceptual design of semi-submersible foundations for deep-sea ultra-large FOWTs.
