Offshore Wind Structural Analysis and Design Software

Explore design alternatives, predict performance, and deliver safe, cost-effective offshore wind farm structures with OpenWindPower.

OpenWindPower Fixed Foundation

Fixed Offshore Wind Turbine Analysis Software

Subject to wave, wind, and mechanical loading, OpenWindPower Fixed Foundation makes it easy to predict fatigue and extreme loads for the substructure and nonlinear foundation.

Analyze Wave and Wind Loading

A wave surface profile may be determined from a wave height spectral density function using multiple random seeds. Wind loading can be input as time history or as a random loading developed from various spectra.

Perform Coupled or Uncoupled Analysis

Interface to the Bladed and FAST v7.1 software and account for the full coupling between wave, wind, and the wind-induced mechanical loading for a multimodal response analysis.

Predict Stress Cycles with Fatigue Analysis

The OpenWindPower Fixed Foundation fatigue analysis method uses the Rainflow counting approach to predict the stress cycles resulting from a time history analysis – including the ability to sequentially accumulate the damage from multiple analysis simulations for numerous wind speeds and seastates.



OpenWindPower software is used to design offshore wind turbines.

Shanghai Investigation, Design & Research Institute Co., Ltd.

“With OpenWindPower, the design team iterated designs to determine the best way to protect the tower foundations from ice damage. Their work resulted in anti-ice cones, which flare out where the tower meets the water. The design … protects the tower foundation by providing a much thicker surface area that deflects floating ice more effectively than a narrower surface.”

Featured Projects

OpenWindPower was used for the China Three Gorges New Energy Dalian Zhuanghe III Offshore Wind Farm Project.

China Three Gorges New Energy Dalian Zhuanghe III Offshore Wind Farm Project

China Three Gorges New Energy and Dalian Power Generation, owners of multiple offshore wind developments in China, contracted Shanghai Investigation, Design, & Research Institute (SIDRI) to design an offshore wind farm in the Bohai Sea. The large project, including 72 wind turbines with a combined capacity of 300 megawatts and a 220-kilovolt booster station, would be built among the trenches and caves of the local sea floor. Additionally, the design would have to protect the wind towers from ice floes during the winter months. The size, complexity, and challenges of this project presented what SIDRI called “second-to-none” difficulty.

OpenWindPower was used for the Block Island Wind Farm by Keystone Engineering Inc.

Block Island Wind Farm – Block Island, Rhode Island, United States

Keystone saved their client 20% in installation costs by using Bentley’s OpenWindPower to design steel jacket substructures for America’s first commercial offshore wind farm.
