Energy expert and assurance provider DNV has released a comprehensive standard for wind turbine load calculations and site assessments, created to guide industry stakeholders.
The standard includes instructions on requirements, principles and guidelines for the assessment of site conditions and the establishment of loads on wind turbines, including support structures.
Recognizing the challenges associated with wind turbine load calculations and site condition assessments, the company has published its DNV-ST-0437, catering to both onshore and offshore applications.
The standard includes project insights and enhancements to International Electrotechnical Commission standards. These additions cover wind extrapolation, tropical cyclones, sea and lake ice, seismic activity and ship impact.
Advanced methodologies for load modeling, such as machine learning-based surrogate models, wind turbine clustering methods and probabilistic-based design principles are also included.
“Stringent industry standards are essential for ensuring the safety, reliability and performance of wind turbines,” says DNV’s Kim Sandgaard-Mørk.
“They allow manufacturers, developers and financiers to evaluate designs and make informed decisions for successful projects. DNV-ST-0437 aims to equip industry stakeholders with the necessary tools and guidance to navigate the complexities of wind turbine load calculations and site assessments in more environments and configurations than before, contributing to the continued growth and success of the wind energy industry by maintaining the highest degree of safety and performance.”
