Abstract Floating offshore wind turbines are becoming increasingly popular as a promising technology for producing cleaner energy. However, in order to be competitive with fixed offshore wind projects or even onshore wind projects, the costs associated with floating offshore wind turbines must be significantly reduced. To tackle this challenge, this paper presents a comprehensive framework for optimizing the design of floating offshore wind turbine substructures and their components. The innovative open-source frequency-domain dynamic model RAFT is used to take into account the aerodynamic, hy

Floating offshore wind turbines are a promising technology for addressing energy needs by utilizing wind resources offshore. The current state of the art is based on heavy, expensive platforms to survive the ocean environment. Typical design techniques do not involve optimization because of the computationally expensive time domain solvers used to model motions and loads in the ocean environment. However, this design uses an efficient frequency domain solver with a genetic algorithm to rapidly optimize the design of a novel floating wind turbine concept. The concept utilizes a liquid ballast m

Currently, floating offshore wind is experiencing rapid development towards a commercial scale. However, the research to design new control strategies requires numerical models of low computational cost accounting for the most relevant dynamics. In this paper, a reduced linear time-domain model is presented and validated. The model represents the main floating offshore wind turbine dynamics with four planar degrees of freedom: surge, heave, pitch, first tower fore-aft deflection, and rotor speed to account for rotor dynamics. The model relies on multibody and modal theories to develop the equa

Floating Offshore Wind Turbines (FOWTs) are ground-breaking systems in the renewable sector, capable to exploit wind energy in deep-water areas, where the resource is stronger and abundant with respect to onshore and near-cost sites. In this work, a coupled Frequency-Domain (FD) model of the entire system is developed and validated against time-domain simulations. The FD model is implemented in site-specific optimization procedures performed by means of Genetic Algorithm (GA, targeted at reducing the costs of the substructure without an uncontrolled penalization of the structural performance

Offshore floating wind turbine technology is growing rapidly and has the potential to become one of the main sources of affordable renewable energy. However, this technology is still immature owing in part to complications from the integrated design of wind turbines and floating platforms, aero-hydro-servo-elastic responses, grid integrations, and offshore wind resource assessments. This research focuses on developing methodologies to investigate the technical and economic feasibility of a wide range of floating offshore wind turbine support structures. To achieve this goal, interdisciplinary

Abstract Most global wind resources are found in water depths exceeding 60 meters, where using bottom-mounted structures is challenging and costly. Thus, increased the studies on floating offshore wind turbine (FOWT) solutions characterized by complex dynamics between the floating structures and turbines. Nowadays, one key challenge is designing optimum mooring arrangements for large-scale FOWT. A meta-heuristic solution is recommended to solve a complex optimization problem, such as the mooring arrangement of a floating wind turbine. Among these, the Evolutionary Algorithms (EA) use mechanism

Abstract A variety of substructure concepts for floating offshore wind have been developed. Design optimization can be used to efficiently explore this design space and guide further work. Previous design optimization studies have been limited by model simplifications, including the assumption of rigid body motions, lack of substructure flexibility, and a focus on a single floating foundation concept. High computational costs of gradient-free optimization methods have limited the number of design variables considered. In this work, gradient-based optimization methods and a frequency-domain mod

Abstract In wind turbine design, various critical aspects demand attention, including wind turbine design, assessment of floater structure, and optimization of the mooring system. Turbine designers prioritize control system optimization, relying on predicting responses like power generation and nacelle accelerations. Evaluating floater structure involves motion responses and loads on interface positions, like the tower base and mooring fairleads. The latter is crucial for positioning system optimization. These considerations often necessitate a comprehensive simulation of the entire system. Th

Abstract In this study, the tension leg platform (TLP) for floating offshore wind turbines (FOWT) has been numerically optimized to minimize pitch motion and tendon tension responses using a surrogate model and the non-dominated sorting genetic algorithm II (NSGA-II). The target platform comprises a central circular column and three offset square columns with connecting pontoons.

Abstract This report describes the ongoing and planned development of the software package CT-Opt (Current/Tidal Optimization), a control co-design modeling tool for marine hydrokinetic turbines. The commercialization of these turbines has faced significant challenges due to the complex, multidisciplinary nature of their design and the extreme environmental conditions of their operation. This project aims to create a modeling tool that will enable the efficient design of robust, cost-competitive hydrokinetic turbine systems. Rather than using traditional optimization methods, CT-Opt combines m
