Bravest Wind’s Post

🌊 Excited to share our latest publication in the Journal of Marine Science and Engineering titled "A Digital Twin for Assessing the Remaining Useful Life of Offshore Wind Turbine Structures"! Co-authored with Julio Garcia-Espinosa, Daniel Di Capua, and Andrés Pastor Sánchez our paper explores the application of digital twin monitoring techniques in optimizing offshore floating wind turbine performance. 🌪⚙️ Through a detailed case study using open-source digital twin software, we delve into real-time structural monitoring and predictive maintenance, focusing on controlling composite wind turbine structures' state and forecasting their remaining useful life. 🏗️ Our findings underscore the potential of digital twins in driving efficiency and sustainability in renewable energy, reducing costly inspections and maintenance. 🌱🔧 Read more about our research here https://lnkd.in/dSjC2zc8 📚 #RenewableEnergy #DigitalTwin #OffshoreWind #MarineScience #Industry40

#towhomitmayconcern : RES-GigaTube : Doubled efficiency at half the weight ! #reswindcolumn PCT application published with research report ! https://lnkd.in/e5Bu4Dvv https://lnkd.in/et9qwc6S https://lnkd.in/eVcSpURp #resgigatube Despite the all-steel construction, the wind column has less than half the design weight of a conventional 7 MW horizontal wind turbine. While the HAWT already has to be down-regulated at wind speeds of more than 12 m/s, the wind column can be operated without regulation at wind speeds of up to 15 m/s. Especially for offshore turbines, which are often exposed to strong winds, the electrical yield in this range can be doubled or tripled compared to a conventional HAWT. This is possible because the optimum performance of the VAWT is already achieved at a resulting inflow that is "only" three times the wind speed. The center segment of the three-part rotor blade #resblade is designed as a rod-shaped support element of the cylindrical lattice shell structure, while the nose segment and the trailing edge segment of the rotor blade can be adjusted by a maximum of 9 degrees relative to the center segment, wherein the suction side of the rotor blade periodically changes from the inner side of the orbit to the outer side of the orbit and vice versa, at a diameter alignable perpendicular to the respective wind direction with two turning points to align the asymmetrically profiled rotor blades in both halves of the orbit to the leeward side. The rotor blade is divided into longitudinal sections and has integrated actuators that have a setting and holding function in the respective longitudinal sections. The design of a cable-stayed lattice shell is scalable and can be made both smaller and larger than the 200 m tower shown here.

#towhomitmayconcern : Energy for Down Under ! German patent granted : https://lnkd.in/ea2iajMR https://lnkd.in/eNYWFN2R International pct application The RES-GigaTube https://lnkd.in/d8a3CkN - combinig a new aerodynamic system with a grid shell structure to produce clean energy for the past Covid future, which soon will start ! In the outback of Australia the Res-Giga Tube with flipped over rotor blades converts kinetic energy of wind into electricity, up to 50 MW and more per unit. The Res-Giga Tube is approximately 480 meters high and has a diameter of about 200 meters at its base. The asymmetrically profiled rotor blades are regularly flipped over at nodal connectors of the grid shell structure changing the orientation of their suction side from the outside to he inside of the orbit. Lambda reaches up to five times the wind speed, allowing the suction force resulting from uplift, - which by the way is one third higher in comparison to a symmetric profile - to be balanced between the leeward half and the wind ward half of the turbine's orbit and vice versa. One revolution of the giant tube lasts more than a minute which is important for its impact on the ecosystem as well as for its visible impression. The structure of the Giga Tube is a hyperbolic grid shell with rigid connections between the rotor blades. #OffshoreWind #OnshoreWind #EnergyTransition #EnergySecurity #EnergyIndependence #EnergyPolicy #GreenEnergy #RenewableEnergy #WindEnergy #ClimateSolution #OffshoreWind #OnshoreWind #EnergyTransition #EnergySecurity #EnergyIndependence #EnergyPolicy #GreenEnergy #RenewableEnergy #WindEnergy #ClimateSolution #offshore #asktheinventor #reswindpower #windenergy #ewing #resblade  www.res-institute.com

#newpaper The limit of wind turbine size we thought was possible has continuously changed over time. What will come next? For most of my PhD, I researched 25 MW offshore wind turbines with a multidisciplinary team. The development of large-scale offshore wind turbines is challenged by higher loads, mass/cost growth, and more flexible blades. This inspired the development of the aero-structural rapid screening (ASRS) approach for conceptual-level design to overcome limitations of long-duration design iterations and determine potential solutions that can be studied in further detail. ASRS is demonstrated using a large set of 25 MW rotors for offshore fixed-bottom wind turbines. ASRS introduces a new design variable for passive load alleviation, blade deflection, and emulates a baseline controller to optimize detailed models of the blade and tower. I invite you to read our paper using the link below (free access until Dec 27). 😊 It includes interesting studies of pre-cone angle and blade deflection, downwind vs. upwind, and variations in rotor aerodynamic design. https://lnkd.in/eF7NKntN Thank you to all the co-authors for your great contributions!

Do you want to understand AEP loss across your entire fleet?   PowerCurve has deployed AeroVista with a top four renewable energy operator to assess the AEP impact of blade damages on a very large sample set of more than 1,500 turbines operating in the USA.   The fleet sample consists of 8 different turbine models of varying ages (~2-15 years) and rotor diameters (~80-120m) experiencing a wide variety of climatic conditions.   The results clearly illustrate the deep insight that can be gained when blade inspection data is combined with advanced aerodynamic modelling. The range of AEP losses is from 0% to 2.7%, with a mean of 0.5%.   Learn more about AeroVista here: https://lnkd.in/ea_BfDsb   #WindTurbines #Blades #AEPloss #aerodynamics #AeroVista”
