DNV has revised the DNV-ST-0376 rotor blade standard, in response to the dynamic landscape of wind turbine development.
The project, tailored to meet the evolving needs of wind turbine developers, owners, and operators, aimed to ensure greater reliability and performance across the industry.
Focusing on addressing the unique requirements of large, flexible blades for multi-megawatt turbines, the revised standard introduces comprehensive measures previously unaddressed in industry norms, DNV said.
During the project, 26 leading companies across the wind turbine sector, including manufacturers, operators, and certifiers, contributed to refining and reviewing the standard.
This inclusive approach ensures a comprehensive framework that caters to the diverse needs of the industry ecosystem, DNV said.
Key highlights of the updated standard include enhanced reliability through rigorous requirements and approaches, and alignment with international standards, facilitating streamlined certification processes.
The standard also includes the introduction of novel concepts such as damage tolerance, elevating safety standards to new heights, and greater focus on design for manufacture and understanding the relationship between manufacturing quality and reliability.
Kim Sandgaard-Mørk, executive vice president for renewables certification at DNV, said: “The pace of modern wind turbine development demands that industry standards keep pace with changing trends and technologies.
“Through the development of industry service documents such as service specifications, standards, and recommended practices, DNV is actively engaged in driving the renewable energy sector forward.
“This update underscores our commitment to driving innovation and quality within the wind energy sector.
“By prioritizing reliability and safety, we aim to bolster industry confidence and propel the global transition towards sustainable energy solutions.”
