FAQS

Find answers

SACS Wind Turbine is an integrated software application for the analysis and design of offshore wind turbine structures. It allows engineers to model the complete system, from the foundation to the turbine, to ensure structural integrity, safety, and compliance against extreme wind and wave loads.

There is no difference in functionality. SACS Wind Turbine is the new name for OpenWindPower Fixed Foundation as of May 2025. The product’s capabilities for comprehensive wind turbine analysis remain the same; the name was updated to better reflect its purpose.

Yes. The SACS Wind Turbine software helps you ensure your designs are compliant with major international standards for offshore wind turbines, such as DNV, IEC, and ISO. This simplifies the regulatory approval process for your global projects.

SACS Wind Turbine is a comprehensive package that includes all capabilities of SACS Offshore Structure Ultimate. It also bundles the advanced SACS Collapse, SACS Pile Structure Design, and SACS Fatigue Ultimate modules, plus interfaces for third-party aeroelastic solvers.

Yes. You can interface with industry-standard aeroelastic solvers like GH Bladed and OpenFast. This allows you to account for the full coupling between wave, wind, and wind-induced mechanical loading for a comprehensive multimodal response analysis.

The fatigue analysis method uses the Rainflow counting approach to predict stress cycles resulting from a time history analysis. It includes the ability to sequentially accumulate fatigue damage from multiple simulations for numerous wind speeds and sea states.

The primary benefit is having a single, integrated solution for all your offshore energy projects. SACS Wind Turbine extends the trusted capabilities of SACS for oil and gas structures with specialized analysis for wind turbines. Instead of using disconnected tools, your teams can apply their skills to both project types within one application. This streamlines workflows, reduces training costs, and makes your business more versatile and ready for the energy transition.
