Huang, M. (author)The development of offshore wind energy, especially the steps towards deep water and/or higher density wind farms, revives the prospects of vertical axis wind turbines (VAWTs). Because VAWTs may reduce the cost of floating structures, there is a potential to lower energy costs. However, VAWTs are often assumed to be less efficient and less...doctoral thesis 2023

van der Tholen, Max (author)Floating offshore wind turbines offer opportunities to harvest wind energy at deep-water locations, where the construction of fixed-base turbines is infeasible. The dynamic power cables, which interconnect turbines and transport the generated electricity, are under large dynamic stresses due to the environmental loads and the motion of the...master thesis 2023

Sensitivity of the seismic response of monopile-supported offshore wind turbines to soil variabilityPanagoulias, S. (author), de Winter, C.M.A. (author), Navalkar, S.T. (author), Nernheim, A. (author)The expansion of the offshore wind industry in areas with high seismicity has led to engineering challenges related to the design of the offshore wind turbines (OWTs). Monopiles, i.e., tubular steel piles of large outer diameter, low aspect ratio (penetration depth over outer diameter), and relatively thin pile wall, are traditionally the...journal article 2023

Huang, M. (author), Sciacchitano, A. (author), Ferreira, Carlos (author)Wake losses are a critical consideration in wind farm design. The ability to steer and deform wakes can result in increased wind farm power density and reduced energy costs and can be used to optimize wind farm designs. This study investigates the wake deflection of a vertical axis wind turbine (VAWT) experimentally, emphasizing the effect of...journal article 2023

Muscari, C. (author), Giordani, R. (author), Schito, P. (author)In this work we test a Fluid–Structure Interaction (FSI) method based on the SOWFA+ OpenFAST framework. The linear structural module of FAST is coupled to SOWFA's Actuator Line simulations to perform the aeroelastic analysis of a wind tunnel scaled model (1:75) of the DTU 10 MW turbine. The objective is to give a quantitative description of...journal article 2023

Frontera Pericas, Pere (author)Floating offshore wind turbines (FOWTs) have the potential to harness wind resources in deepwater, which is so far prohibitive for conventional approaches. This, however, comes at a cost: the platform’s extra degrees of freedom (DoFs) introduce complex aerodynamic and hydrodynamic behaviours. Therefore, FOWTs must be accurately modeled to reduce...master thesis 2022

Saccone, Cecilia (author)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that using floating turbines allows them to move to deeper waters, reducing visual and environmental impact and allowing footprint...master thesis 2022
