A Modelling Study of Hamakaze Fowt
Offshore Technology Conference Asia, 2022Abstract Offshore wind farms are venturing into deeper water, where wind is steadier and stronger, to tap on more wind energy. The installation of wind turbines in deeper waters requires the use of a floating wind turbine. Designing the floating platforms is challenging as dynamic effects waves, wind, and currents, have to be considered.

Formulation and Validation of a Novel Actuator Line Model for FOWT Applications
Volume 14: Wind Energy, 2023Abstract The paper presents a novel in-house CFD solver featuring an original formulation of the Actuator Line Model (ALM), implemented into the OpenFOAM software. The new formulation samples the velocities close to the body-force application point, so to eliminate any effect of the oscillations and disturbance from the sampling.

Ocean Engineering, 2023
This paper proposes a semi-analytical MacCamy–Fuchs–Morison (MFM) hybrid hydrodynamic model for very efficient simulations of FOWT responses without resorting to potential flow solvers. First, closed-form expressions of the 6-by-6 added mass matrix and 6-dimensional complex wave load transfer function are derived based on the Morison equation ...

Hydrodynamic Simulations of a FOWT Platform (1st FOWT Comparative Study) Using OpenFOAM Coupled to MoodyCore [PDF]
, 2023 We numerically simulate the hydrodynamic response of a floating offshore wind turbine (FOWT) using CFD. The FOWT under consideration is a slack-moored 1:70 scale model of the UMaine VolturnUS-S semisubmersible platform. This set-up has been experimentally tested in the COAST Laboratory Ocean Basin at the University of Plymouth, UK. The test cases under

Impact of Viscous Damping Linearization on FOWT Control Design
ASME 2023 5th International Offshore Wind Technical Conference, 2023Abstract Control design is traditionally carried out based on simplified linear models and subsequently tested on more realistic non-linear time domain models of a system. Issues with control performance and robustness can be introduced if the linear model is not representative of the real system, requiring additional design and testing ...

FOWT Coupled Model and Comparison With In-Situ Measurements
ASME 2025 6th International Offshore Wind Technical ConferenceAbstract Modeling floating offshore wind turbines is key to improving their performance, reliability, and design efficiency. Aero-hydro-mechanical software packages have been developed to capture the global behavior of the whole system under various environmental conditions.

Semi-Submersible FOWT with Small Mooring Footprint
Offshore Technology ConferenceAbstract A novel Vertically Moored Semisubmersible (VMS) for deep water is proposed as a small footprint and cost effective floating offshore wind turbine (FOWT). In contrast to the stiff tendons in a conventional Tension Leg Platform (TLP), VMS is a ‘soft’ system with long natural periods in its heave, pitch and roll modes and ...

Design of Floating Offshore Wind Turbine (FOWT) “SelfAligner”
2020The CRUSE Offshore GmbH has invented an innovative floating structure foundation for offshore wind turbines by using the forces of nature. The structure is a semi-submersible, self-aligning platform. The foundation is moored at a single point and uses a turret buoy to rotate freely around its anchor point.
