Wave effect mitigation on floating offshore wind turbines through feedforward data-driven predictive control

Floating Offshore Wind Turbines (FOWTs) pave the way to accessing deep water regions with abundant wind resources that are unreachable to bottom-fixed turbines. This technology is not widely deployed due to the increased cost of producing energy. A suitable control strategy can improve the power quality and extend the lifespan of the FOWT,...

Optimisation of Floating Offshore Wind Substructures: A Higher-Fidelity Approach

Floating offshore wind turbines (FOWTs) unlock the potential to harness energy from wind in deeper waters. Despite their potential, the major obstacle to large-scale commercial deployment remains the floating substructure's high cost. Multidisciplinary design, analysis and optimisation techniques are commonly employed to improve their cost...

An improved, coupled frequency domain model for floating offshore wind turbines including aerodynamics, hydrodynamics and control

Modelling of Floating Offshore Wind Turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating structure, which makes the dynamic response of the whole system highly complex. A variety of numerical approaches can be used to predict this response.<br/><br/>The frequency...

Comparative feasibility study of a 30 MW disruptive floater solution with a 15 MW PivotBuoy and a benchmark 15 MW semi-submersible floater in the Bay of Biscay

This paper investigates the technical, life cycle, and economic feasibility of a 30 MW upscaled downwind turbine, comparing it to a 15 MW X1 Wind PivotBuoy downwind turbine and a benchmark 15 MW IEA Umaine VolturnUS-S upwind turbine in the 450 MW Sud de la Bretagne I wind farm site. The study is significant due to the rising energy demand, the...

A Finite Element Analysis Investigation of Fatigue and Corrosion of Floating Offshore Wind Turbine Mooring Lines

With the rising demand for renewable energy, floating offshore wind turbines have gained importance, particularly in regions where deep waters prevent the use of traditional monopile structures. These floating turbines rely on mooring lines for stability against environmental conditions, particularly when facing strong winds and high waves....

Large-Eddy Simulation of a Floating Offshore Wind Turbine with imposed motion

As the urge to decarbonise the energy field becomes increasingly important, a growing interest is shown in wind turbine technologies. In particular, the past few years have seen the development of floating offshore wind turbines for applications in deep waters.<br/><br/>In addition to the harsher environment they are facing, these wind turbines...
