Special Issue Information

Dear Colleagues,

Although offshore wind turbines (OWTs) have seen rapid growth in the past decade, the further development of these structures to reduce the levelized cost of energy (LCOE) needs proper experimental and numerical analysis. Therefore, research-driven developments to explore new concepts/structures, testing methodologies, numerical modelling tools and simulation methods are required.

Offshore wind turbines are subject to complicated loads and load effects, which demand a comprehensive numerical modelling representation of the physics. Important factors affecting the design, functionality, structural integrity and performance of offshore wind turbines include-but are not limited to-fluid-structure interaction, controller actions, intense dynamic effects, non-linear loadings, extreme and harsh weather conditions, and impact pressure loads. The interdependence between loads, load effects and structural strength requires more advanced numerical tools, nonlinear modelling and innovative testing procedures.

We invite researchers and scientists to contribute original research articles that will stimulate the continuing progress of the OWTs field, with a focus on state-of-the-art numerical modelling and the experimental assessment of offshore wind engineering. We are particularly interested in articles describing new methodologies, analytical and numerical tools, as well as theoretical methods dealing with engineering problems. Potential topics include, but are not limited to:

  • Innovative experimental methods
  • Scaling and scale effects
  • Statistical methods and environmental resource assessment
  • Wind, wave and current interactions
  • Comprehensive handling of engineering problems, in particular, design aspects
  • Numerical methods for structural and fluid dynamics
  • Computational fluid dynamics (CFD)
  • Finite element methods (FEM)
  • Fluid–structure interaction (FSI)
  • Aero-hydro-servo-geo-elastic models for fixed and floating offshore wind turbines
  • Automatic control methods applied for OWTs engineering problems
  • Robust nonlinear models for fast simulation
  • Comprehensive numerical methods for high-fidelity simulation of behaviour and functionality
  • Verification and validation, code-to-code comparison, as well as experiments
  • Insight into the philosophy and power of numerical simulations
  • Nonlinearities in physical systems and numerical models
  • Coupled effects between floater and mooring system
  • Soil–structure interaction
  • Higher order wave loads and responses
  • Field and laboratory testing and experimental procedures

The growing interest in renewable energy solutions for sustainable development has significantly advanced the design and analysis of floating offshore wind turbines (FOWTs). Modeling FOWTs presents challenges due to the considerable coupling between the turbine’s aerodynamics and the floating platform’s hydrodynamics. This review paper highlights the critical role of computational fluid dynamics (CFD) in enhancing the design and performance evaluation of FOWTs. It thoroughly evaluates various CFD approaches, including uncoupled, partially coupled, and fully coupled models, to address the intricate interactions between aerodynamics, hydrodynamics, and structural dynamics within FOWTs. Additionally, this paper reviews a range of software tools for FOWT numerical analysis. The research emphasizes the need to focus on the coupled aero-hydro-elastic models of FOWTs, especially in response to expanding rotor diameters. Further research should focus on developing nonlinear eddy viscosity models, refining grid techniques, and enhancing simulations for realistic sea states and wake interactions in floating wind farms. The research aims to familiarize new researchers with essential aspects of CFD simulations for FOWTs and to provide recommendations for addressing challenges. Full article

This paper presents a comprehensive review of advanced control methods specifically designed for floating offshore wind turbines (FOWTs) above the rated wind speed. Focusing on primary control objectives, including power regulation at rated values, platform pitch mitigation, and structural load reduction, this paper begins by outlining the requirements and challenges inherent in FOWT control systems. It delves into the fundamental aspects of the FOWT system control framework, thereby highlighting challenges, control objectives, and conventional methods derived from bottom-fixed wind turbines. Our review then categorizes advanced control methods above the rated wind speed into three distinct approaches: model-based control, data-driven model-based control, and data-driven model-free control. Each approach is examined in terms of its specific strengths and weaknesses in practical application. The insights provided in this review contribute to a deeper understanding of the dynamic landscape of control strategies for FOWTs, thus offering guidance for researchers and practitioners in the field.
