FLOATBench: A Dataset and Benchmark for Floating Offshore Wind Turbine Tower Fatigue
TL;DR
Floating offshore wind turbines (FOWTs) face challenges in predicting tower fatigue due to varying simulation methods. FLOATBench was developed as a public benchmark dataset containing 582,120 fatigue-damage labels from 19,404 high-fidelity simulations across three tower geometries.
✦ Why It Matters
Engineers can utilize FLOATBench to enhance fatigue prediction accuracy and optimize the design of floating wind turbine towers.
Key Takeaways
- Use FLOATBench for standardized fatigue prediction comparisons.
- Leverage high-fidelity simulation data for design optimization.
- Implement regime-aware evaluation to detect performance shifts.
- Adopt reproducible protocols for benchmarking engineering models.
Full Summary
As offshore wind energy expands into deeper waters, floating offshore wind turbines (FOWTs) are essential for harnessing this resource. However, predicting tower fatigue is complicated by the diverse simulation approaches used in the field.
FLOATBench was created to address this gap, providing a comprehensive dataset with 582,120 fatigue-damage labels derived from 19,404 OpenFAST simulations across three different 22 MW FOWT tower designs. Each tower's data includes 30 cross-sections and is stratified into in-train, interpolation, and extrapolation regimes based on wind and wave conditions.
The benchmark also features a reproducible evaluation harness with three testing protocols, revealing performance differences that random validation methods might miss. FLOATBench is the first of its kind for FOWT fatigue modeling, offering a standardized approach for engineers and researchers to improve design and certification processes.
