Our Services

Simulations

With a deep understanding of the general dynamics of bottom-fixed foundation wind turbines and floating wind turbines we use different simulation models to analyze wind turbines. Besides commercial simulation tools, we have developed and maintain an in-house simulation model, SLOW with a specific focus on computational efficiency. Our software is the worlds fastest aero-hydro-servo-elastic simulation model, making it a unique solution for streamlined Integrated Loads Analysis in each design phase. In early design stages, we have tailored order-reduction schemes, which accelerate large sets of lifetime load assessments. In advanced design we perform design load calculations (DLCs) according to IEC or DNV standards. 

sowento is expert user of NREL’s OpenFAST, Orcina’s Orcaflex and DNV’s Bladed software for bottom-fixed and floating wind turbines.

sowento develops and maintains a simulation  manager for large batches of Design Load Simulations for offshore wind turbines according to IEC or DNV. The pywento toolbox preprocesses and postprocesses load cases independent of the simulation software. It is designed with a focus on robust runs with automated plausibility checks, tracking of tailored design indicators throughout the design process and results reproducibility at any time.

 

Integrated-design and optimization

Our experienced team of engineers collaborates with clients to develop innovative floating wind turbine designs that maximize energy production while adhering to safety and design load standards. Through meticulous analysis and iterative refinement, we optimize wind turbine systems to enhance performance, reduce costs, and extend operational lifespan.

sowento has unique experience in the simulation of innovative foundation concepts for offshore wind turbines. These include multi-rotor foundations, lightweight designs and weathervaning single point-mooring systems.

Wind turbine control

Leveraging state-of-the-art control algorithms, we engineer sophisticated control systems for wind turbines, ensuring precise operation and stability in diverse operating conditions. We provide baseline controllers for onshore, offshore, and floating wind turbines, very close to industrial practice. Moreover, our FBsowento controller offers the potential of increased control performance and an optimized operation of the wind turbine.

Especially for floating wind turbines with two-turbines on one floating platform, we offer unique master controllers, which find the best tradeoff between the loading and stabilizing the yaw motion best. Get in touch to learn more about our track record.

Lidar-assisted control

We are the world leading team realizing lidar-assisted control for wind turbines. Having worked with different wind turbines, in different sites, on- and offshore, we know the challenges introducing lidar-assisted control. We support our clients in making the right decisions from feasibility studies, to detailed design, analysis and controller optimization, field-testing and commercialization. In our vision every wind turbine is equipped with a nacelle-based lidar and makes use of this unique sensor.

Lidar applications

We have developed and shaped different lidar applications like e.g. lidar-assisted control, lidar data correction of floating lidars, power performance assessment in the induction zone, advanced wind field reconstruction, or motion correction of lidar data from floating wind turbines. Through involvements in expert committees we have shared our knowledge and have supported the industry adapting new lidar applications.

Together with our partners we continuously develop further our methods and support the application of lidars. Get in touch to partner with us.

 

Taylored software solutions

In our understanding taylored software solutions are key to leverage expertise and address the complexity of the problems in wind energy. sowento’s specialized software engineering team develops in-house software as well as client specific software solutions to address the need of translating expertise and knowhow into applicable processes and software programs.
