Numerical Simulation of a Floating Offshore Wind Turbine in Wind and Waves Based on a Coupled CFD–FEA Approach

Journal of Marine Science and Engineering
A floating offshore wind turbine (FOWT) normally suffers from complex external load conditions. It is vital to accurately estimate these loads and the subsequent structural motion and deformation responses for the safety design of the FOWT throughout its

Power Quality‐Oriented Multiloop Design of Floating Wind Turbines Pitch Control

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT Floating offshore wind turbines (FOWTs) face inherent control limitations in above‐rated operating conditions due to right‐half‐plane zeros in the blade‐pitch‐to‐rotor‐speed dynamics, which restrict achievable control bandwidth and may lead to closed‐loop instability.

Influence of steady and turbulent wind on motions, mooring tension, and fatigue performance of a steel OO-Star floating offshore wind turbine

Frontiers in Energy Research
Floating offshore wind turbines (FOWTs) often operate under turbulent wind conditions. However, to enhance computational efficiency, steady wind is sometimes used as an alternative to turbulent wind, potentially resulting in conservative estimates ...

A novel multi-dimensional reliability approach for floating wind turbines under power production conditions

Frontiers in Marine Science, 2022
Floating offshore wind turbines (FOWT) generate green renewable energy and are a vital part of the modern offshore wind energy industry. Robust predicting extreme offshore loads during FOWT operations is an important safety concern.

A Structured Techno‐Economic and Socio‐Regulatory Comparison of Onshore, Fixed‐Bottom Offshore, and Floating Offshore Wind Energy Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Onshore, fixed‐bottom offshore, and floating offshore wind turbines (FOWTs) represent distinct technological pathways for large‐scale wind energy deployment, yet comparative assessments often emphasize descriptive characteristics rather than quantified performance trade‐offs.

Linear Quadratic Optimal Control of a Spar-Type Floating Offshore Wind Turbine in the Presence of Turbulent Wind and Different Sea States

Journal of Marine Science and Engineering, 2018
This paper presents the design of a linear quadratic (LQ) optimal controller for a spar-type floating offshore wind turbine (FOWT). The FOWT is exposed to different sea states and constant wind turbulence intensity above rated wind speed.

Tracking Mooring Lines of Floating Structures by an Autonomous Underwater Vehicle

Journal of Field Robotics, Volume 42, Issue 8, Page 4589-4608, December 2025.
ABSTRACT This study presents a novel method for tracking mooring lines of Floating Offshore Wind Turbines (FOWTs) using an Autonomous Underwater Vehicle (AUV) equipped with a tilt‐controlled Multibeam Imaging Sonar (MBS). The proposed approach enables the AUV to estimate the 3D positions of mooring lines and safely track them in real‐time, overcoming ...

Scaled Physical Modelling of Floating Offshore Wind Turbines Using a Neural Network‐Based Surrogate Model for Aerodynamic Emulation

Wind Energy, Volume 28, Issue 10, October 2025.
ABSTRACT Scaled physical modelling of floating offshore wind turbines is a crucial step in the continued development of floating offshore wind to reach Net‐Zero goals. However, it is an inherently difficult task due to the incongruity between Reynolds scaling (important for wind effects) and Froude scaling (important for wave effects).

Review of Study on the Coupled Dynamic Performance of Floating Offshore Wind Turbines

Energies, 2022
Floating offshore wind turbines (FOWT) have attracted more and more attention in recent years. However, environmental loads on FOWTs have higher complexity than those on the traditional onshore or fixed-bottom offshore wind turbines.
