Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO157: Development of the international design standards for bottom-fixed offshore wind turbines
Tim Camp, Director of Innovation, OWC
Abstract
The offshore wind industry has come a long way since the first offshore wind farm was developed in 1991. However, offshore wind technology is still advancing at pace and design standards need to evolve so that they can continue to define industry best practice. The International Electrotechnical Commission (IEC) standard IEC 61400-3-1 provides authoritative guidance on design loads for bottom-fixed offshore wind turbines but lacks detailed provisions for support structure strength assessment. Conversely, the ISO 19900 series, originally developed in the 1990s by the offshore oil and gas industry, offers extensive expertise in structural design but minimal application to offshore wind. Following a scope revision in 2021 to include lower carbon technologies, future iterations of the ISO 19900 series aim to support the design of offshore wind support structures. To bridge the gap between load and strength guidance, the IOGP JIP35 initiative has explored the integrated use of IEC and ISO standards for offshore wind structural design. Findings indicate that target reliability levels, safety factors, and design return periods of extreme events are broadly consistent between the two sets of standards, supporting their combined use. Furthermore, expert reviews and stakeholder interviews have identified key areas for development within the ISO standards to enhance their relevance to offshore wind projects. This work lays the foundation for a harmonized design framework that leverages the strengths of both IEC and ISO standards to support the evolving needs of offshore wind engineering.
