Floating Wind Engineering

We bring our modeling and system’s theory experience into your floating wind project! With our passion and broad experience in challenging engineering questions, we will contribute to our joint project in an efficient and individual way. Our multidisciplinary understanding (wind, structure and offshore engineering) of the coupled dynamics of floating substructures and wind turbines, modern control methods, holistic system optimization and design studies contribute to the realization of floating wind turbines. Whether you are at an early stage of your floating wind project or in the certification phase, at wave tank or prototype testing, in an up-scaling phase, or already in operation, you can benefit from our experience and expertise in the field.

Our engineering expertise enables us to accompany the entire floating wind project and provide solutions.

These are mainly

  • Feasibility studies
  • Simulation and engineering studies
  • Integrated FOWT system design and optimization
  • Technological due diligence
  • Controller design
  • Measurement data evaluation
  • Software solutions

Floating Wind Software Solutions

Our core expertise in software development is delivering modular, scalable, highly flexible and computational efficient products. We aim at user-friendliness while giving the advanced user full access to all possible settings.

The most established and well-known of sowento’s floating wind solutions is the SLOW model (Simplified Low-Order Wind turbine), which we use in-house for FOWT controller design and concept design studies. It represents not more than the main, design-driving dynamics and physical effects, while ensuring a very high computational efficiency (4000x real time). It is available in a nonlinear and corresponding linearized formulation. Building on the validated and well-documented tool, we offer the following solutions:

New developments and innovations need strong decisions. However, sometimes the important information to make such decisions is missing.

We support our customers with our many years of experience and our insight into the technology in making decisions and help them to take the right direction. As an independent consultant, the interests of our customers are our first priority and we work to develop individual and tailored solutions with our customers.

Over the recent years, sowento and OWT have cooperated successfully in developing floating offshore wind structures. sowento was responsible for all coupled analyses and controls and we at OWT transferred their coupled loads into our FE-models of the components. We have formed a strong and reliable partnership and are looking forward to building on this fruitful and efficient collaboration in the future.
