This update, a product of joint industry collaboration, marks a significant milestone in enhancing reliability and safety within the wind energy sector.</p> <p>In the fast-evolving realm of wind turbine technology, heightened reliability standards are crucial to keep pace with advancements. 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.</p> </div> “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,” adds Kim Sandgaard-Mørk, Executive Vice President for Renewables Certification at DNV. “By prioritizing reliability and safety, we aim to bolster industry confidence and propel the global transition towards sustainable energy solutions.” <p>“Not all wind turbine blades are created equal,” says Christopher Harrison, Principal Engineer and Service Line Leader for Component Certification, Energy Systems at DNV. “Different design assumptions and methods, along with varying performance during validation tests, can result in differing blade performance over their lifespan. As stakeholders in the wind energy sector, it’s crucial to understand and mitigate these risks.”</p> <p>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.</p> <p>Key highlights of the updated standard include:</p> <p>Enhanced reliability through rigorous requirements and approaches.</p> <p>Alignment with international standards, facilitating streamlined certification processes.</p> <p>Introduction of novel concepts such as damage tolerance, elevating safety standards to new heights.</p> <p>Greater focus on design for manufacture and understanding the relationship between manufacturing quality and reliability.</p> <p>Unlike previous standards solely focused on safety, DNV-ST-0376 sets a new benchmark by incorporating reliability as a cornerstone principle. The initiative focused on three key areas:</p> <p>Quality design standard: DNV revised the blade standard DNV-ST-0376 to address real-world failure modes and defects for large flexible blades in multi-megawatt turbines.</p> <p>Alignment with other international standards: DNV aligned requirements in DNV-ST-0376 with IEC 61400-5 where possible, with input from other certification bodies.</p> <p>Stakeholder education: DNV conducted seminars in Hamburg, Copenhagen, and Shanghai to educate developers, owners, and operators on the relationship between design assumptions, testing performance, and long-term blade functionality, enabling informed decisions in turbine certification.</p> <p>“Our goal was to provide wind turbine stakeholders with the tools and knowledge necessary to navigate the complexities of blade development,” concludes Christopher Harrison. “By working together through this joint industry project, we could drive improvements in standards that benefited the entire industry.”</p> </div> </div> </div> <div class="fl show-keywords_small"> <h2 class="t title-ff fwb fz18 black tr show-keywords-title p20 fl"> Keywords </h2> <div class="fr fz18 keywords"> <i class="iconfont icon-icon-down"></i> <a href="https://www.world-energy.org/search.html?keyword=wind energy">Wind Energy</a> </div> <div class="fr fz18 keywords"> <div class="fixedad ad mt10 mb30" style="width: 630px;
