Spiralis Energy’s Post

New CFD Simulation, published today ! After almost a year of continued collaboration between Cape Horn Engineering and tidal energy developer, Spiralis Energy Ltd, we are proud to present the first validation results of our CFD analysis with a 6-meter 1/4 scale test rig deployed at Poole Harbour, UK, in real-world conditions. This is a very valuable first step towards our ambitious plans of deploying full-scale axial tidal energy converters that could revolutionise the renewable energy landscape. We are currently working on a 16m length by 5m diameter "Skelter" to be tested over the harsh winter conditions. Our simulations are key to understanding the loads on the structures and optimising the hydrodynamic shape of the Skelter for maximum performance. Spiralis Energy aims to power up 11% of the national grid using its tidal energy technology. “The UK has the best tidal knowledge in the world. Our technology can deliver a renewable energy source that doesn’t harm sea life and sits within the circular economy framework,” said Chief Executive of Spiralis Energy, Guy Levene OBE Levene OBE. “What makes Spiralis easy-to-scale is that our units have a modular design to enable them to fit into a standard shipping container for affordable transportation anywhere in the world. It’s really quite straightforward – we’re offering a simple, more affordable, more reliable and sustainable energy solution; our technology simply works.” Spiralis is to test two of its Axial Skelter power-generating screws in the waters off Alderney in the Channel Islands. With some of the strongest tidal currents in Europe, and thanks to its unique seabed ownership, Alderney supports project development. The CFD simulations were processed on a High-Performance Computing (HPC) cluster using the best-in-class software package Simcenter STAR-CCM+ in the latest version from Siemens Digital Industries.

As the energy landscape evolves, the demand for #PowerTransformers is soaring, fueled by the global shift to renewable energy sources and the electrification of transportation. However, in seismic-prone regions, ensuring the structural integrity and continuous functionality of these components is critical. In our blog, we dig into the specific challenges of Power Transformer seismic qualification: https://lnkd.in/dhida4xd #SubstationEquipment #SeismicDesign #PowerInfrastructure #StructuralAnalysis #PowerTransformer #SeismicQualification #RenewableEnergy #EarthquakeEngineering

💡 #Highcitedpaper 🌊 Title: State-of-the-Art Review of Vortex-Induced Motions of Floating Offshore Wind Turbine Structures 🔑 Keywords: #vortex-induced motions (VIM); vortex-induced vibrations (VIV); #floating #offshore #windturbine (#FOWT) 🔗 Read More: https://lnkd.in/gJTw9fr8 📜 Abstract: The motivation for this study is the fast development of floating offshore wind energy and the immature methodology and engineering practice related to predictions of vortex-induced motions (VIM). Benefiting from the oil and gas industry, in the past several decades, extensive knowledge and experience on vortex-induced vibrations (VIV) on slender marine structures has been gained. As the learnings from these efforts should be transferred and adapted to the renewable energy industry, a state-of-the-art review on influential VIM research has been carried out in this paper, focusing on: (1) engineering practice, (2) model tests, (3) numerical calculation, and (4) field measurement. Engineering gaps and potential research topics are identified as future work.

👨💻Installing wind turbines is a complex task, so research and development are essential considering the growing size of the turbines and the challenges that follow🏗📑 Among the latest contributions is the paper by Alessio Torrielli from R&D Test Systems, Alessandro Giusti from Siemens Gamesa, Stefano Brusco and maria pia repetto from University of Genoa: “The contribution of higher order modes in the dynamic response of slender vertical structures with application to wind turbine towers" just now published in journal Engineering Structures. Simply put, the research focuses on the vibrations of offshore wind turbine towers placed at the port quayside under seismic excitations. The challenge is that the seismic forces and large vibrations can cause the tilting of the foundation and so compromise the tower’s integrity before offshore installation. This piece of research can be used to assess safety and optimize the design of the temporary foundation at the port quayside. At R&D Test Systems, we are proud of our skilled consultants who contribute to the research and development of wind power.

Prediction Model for Movement and Life Expectancy of Subsea Cables under Wave and Current Action The predominant failure modes of subsea cables are associated with extreme environmental conditions. Wave-forcing during severe storms is less expected and causes more damage. A generalized multiphysics cable model is constructed to predict the movement, damage, and lifetime of subsea cables subject to dynamic wave and current action due to abrasion and corrosion. The present cable lifespan prediction model extended the previous tide-only model by considering the contribution of hydrodynamic forces by waves and the effect of wave and current incident angle relative to the cable. The predicted cable sliding distance at each section of the cable is combined with the Archard abrasion wear model and the corrosion model to predict the loss of cable protective layers and the resulting expected lifespan of the cable. Our new model is the first of its kind that can predict the spatial variation of wave and current loading, cable movement, damage, remaining lifetime, and cable failure modes and location. In addition, spatial and temporal variations of magnitude and direction of wave, current, and tide can be incorporated into the model for realistic large-scale simulations of cable performance in field conditions. The model compares well with previous laboratory experiments and numerical models. The present model was applied for the first time to the European Marine Energy Centre (EMEC)’s wave test site located at Billia Croo off the west coast of mainland Orkney, Scotland, and validated by the cable lifespan data. The 1-year and 100-year return period wave height and period and the average wave and tide conditions are used to drive the present cable lifespan model. It was found that the cable movement is predominantly driven by waves, and the previous tide-only model would predict zero cable movement, indicating the importance of the incorporation of wave contribution into the cable model. Furthermore, besides wave height and period, the wave angle relative to cable was found to be a determining factor for the cable movement and lifespan. The present multiphysics cable model provides a new capability to predict 70% of failure modes currently not monitored in situ and to deploy, plan, and manage subsea cables with improved fidelity, reduced cost, and human risk. https://lnkd.in/dYkwrJqJ Great collaboration between University of Glasgow and Heriot-Watt University. #criticalnationalinfrastructure #subsea #powercables #energy #forecasting #assetmanagement

Our latest work on #tidal #turbine modelling is on "Efficient prediction of tidal turbine fatigue loading using turbulent onset flow from Large Eddy Simulations" (https://lnkd.in/dWY_srz5) led by Hannah Mullings, MEng PhD CEng MIMechE FHEA in collaboration with Orbital Marine Power Ltd. Current IEC/DNV standards (and software) assume idealised conditions for evaluating turbine loading. However, higher fidelity data, e.g. from specific flow conditions or sites, can be generated with #LES (we used our code #DOFAS) to improve confidence in design. It is a relatively "cheap" approach to generate realistic inflow conditions. For turbine #arrays, we show the prediction of loading by LES with actuator line and BEM (in-house code and TidalBladed). TB predicts higher thrust for downstream rows. We hope this approach can be taken up in future design campaings by the whole industry and perhaps expanding to wind turbines too.
