SeaTwirl Uses Ansys Tools to Optimize the Design of Offshore Wind Turbines
“Ansys tools, obtained through the Ansys Startup Program, allowed us to achieve one single simulation environment in which hydrodynamic analyses, CFD and structural FEM could be deployed to speed up the SeaTwirl developing process.”
— Martin Rosander Sr. Structural Engineer / SeaTwirl AB
SeaTwirl AB is a Swedish SME established in 2012. Since December 2016, the company is listed on the NASDAQ First North Stockholm under the STW sticker. SeaTwirl develops and sells innovative, vertical-axis floating offshore wind turbines. They are easier to install, operate and maintain, and offer a better levelized cost of energy (LCOE) versus other turbines. SeaTwirl has a clear vision: to be the industry-leading, floating offshore wind company by 2030.
Overall SeaTwirl challenge:
The SeaTwirl floating offshore wind turbine features a spar buoy supporting a vertical axis wind turbine. SeaTwirl is currently designing a commercial size demo of 1 MW to be installed at a test site in 2020. It is very important for us to be able to simulate different load cases for our designs to validate our technology for future investors, third-party verifications, regulators, insurance purposes and, ultimately, for receiving necessary certificates.
We were able to make important development decisions regarding our design. We actively investigated technical as well as commercial aspects based on the simulation results. We used Ansys software to design and analyze:
