Yes, you read that right—float. You may have seen a wind turbine in the sea before, but chances are you were looking at a “fixed” turbine—that is, one that sits on top of a foundation drilled into the seabed. For the new frontier of offshore wind power, the focus is on floating wind turbines. In this case, the turbines are supported by floating structures that bob and sway in response to waves and wind and are moored with chains and anchored to the seafloor.

Floating wind turbines move (of course) and so do the electrical cables connected to them. This creates potential for interference between mooring lines that keep turbines in place and the dynamic cables for electricity collection. It also creates potential strain in the cables in operation. This work led by Juan-Andrés Pérez-Rúa funded by TotalEnergies in the DTU-TotalEnergies Excellence Centre of Clean Energy (DTEC) collaboration is a first to look at these dynamics in the context of design of wind farm electric collection systems. Very relevant work as the floating wind industry seeks to scale from small commercial projects to GW-scale wind farms of 50-100 turbines.

We are happy to share our latest article, now published in Renewable Energy [Elsevier, In Press]. In this work, we tackle the complex challenge of optimizing inter-array dynamic cable networks for Floating Offshore Wind Farms. Our approach introduces innovative modeling techniques that integrate engineering constraints from both hydrodynamic and thermal analysis, which significantly differentiate this problem from its fixed-bottom counterpart. We further embed these models into a neighborhood search heuristic to enhance tractability and efficiency. The experimental results highlight that introducing new degrees of freedom - such as coupling dynamic and static cables and allowing non-linear trenching - can lead to reduced investment costs, albeit with a significant increase in model complexity. We invite you to explore the full article here: https://lnkd.in/dJuawDTZ Katherine Dykes, David Verelst, Rasmus Sode Lund, and Asger Bech Abrahamsen Likewise, thanks to LARS OBERBECK @Matthieu Hochet jean-philippe roques and Arsim Ahmedi for their their inputs along the execution of this project. #MathematicalModeling #NumericalOptimization #FloatingWindFarms #HydrodynamicAnalysis #RenewableEnergy

MIT engineers have developed a new theory to improve the design and operation of #windfarms. This theory provides a more accurate explanation of how wind turbines interact with each other and how air flows around them. Unlike traditional approaches, the new model aims to optimize turbine placement and performance, enhancing energy production and making wind farms more efficient. This approach could lead to significant advancements in the use of #windenergy.

I have seen offshore floating wind developments in the news a lot recently but I think the Qingzhou IV OWF in Yangjiang, Guangdong tops them all. It is predicted to produce enough power annually to support 30,000 homes by it's self. I know wind turbines get a lot of stick for not looking visually appealing but this one could change a few minds! I am however slightly concerned about the O&M process on these twin turbines. Keen to hear some thoughts from my engineering network on the design? #floatingwind #design #offshorewind #engineering

PRINCIPLE POWER FLOATS NEW DESIGNS FOR OFFSHORE WIND GIANTS Floating wind technology specialist Principle Power has expanded its WindFloat portfolio with the introduction of two new floating wind foundation designs: WindFloat TC and WindFloat FC. These new models are specifically optimized for 15 MW+ wind turbines, marking a significant evolution in floating wind technology. The WindFloat TC features a tubular centre column, while the WindFloat FC utilizes a flat-panel design. Both designs build on existing WindFloat technologies, which support wind turbines mounted on a central column. Key features include a Smart Hull Trim system aimed at maximizing energy production and reducing structural loads, as well as fatigue-resistant architecture tailored for large turbines. Additionally, the compact footprint and shallow draft of these foundations enhance compatibility with existing infrastructure. These advancements in design are expected to improve cost-effectiveness and performance, making them suitable for a wide range of wind turbine models as the floating wind market continues to grow. ⚡ Follow MPS (Modern Power Systems) for all the latest news daily from the global power generation industry ⚡ #MPS #power #windpower #floatingwind #renewableenergy

At the system level, both fore-aft and side-to-side fatigue will be accounted for to ensure that the natural frequencies of the structural components do not coincide with operational frequencies, thereby avoiding resonance and excessive vibration during operation. It is crucial to capture the fore-aft magnitude of extreme high-intensity (HI) wind events in static conditions to assess fatigue separately for the blade and nacelle, ensuring overall structural component integrity and its interaction with the foundation. Fortunately, the short duration of HI winds typically prevents the connection and tower shell plate from yielding due to fatigue, provided they pass the strength limit. #system #level #structural #Windturbine.
Wind turbine nodding, also known as 1st tower fore-aft, refers to the movement of the tower in the direction of the wind. This phenomenon can lead to fatigue and, in extreme cases, catastrophic failure. As such, it's essential for engineers to verify that a wind turbine design can withstand site-specific fatigue loads throughout its entire design lifetime. The dynamic behavior of the blades and nacelle must be separated from the tower in terms of structural natural frequencies to prevent resonance. If the frequency of the blade's torsional or transversal modes is close to that of the tower, nodding resonance is likely to occur. To mitigate this issue, engineers must consider system-level design, ensuring that the wind turbine's components are designed to work together harmoniously. Neglecting this aspect can lead to problematic consequences. Note: This illustration is a scaled-up version of wind turbine nodding, intended to help visualize the phenomenon easily. In reality, the movement is much more subtle and not as exaggerated as depicted here.
