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 the academic community. We look forward to seeing you there!

PO290: A call for standardization of sea fastening interfaces: The potential of life extension and reusing steel structures

Quentin Meissonnier, Head of Project Engineering, Cadeler A/S


Executed properly, sea fastening enables the final safe and efficient transportation of key project equipment such as turbine components for the installation of offshore wind farms. This is a highly critical stage of the entire project, both in terms of manufacturing costs and vessel preparation prior the intricate installation. Optimizing this critical stage must not be underestimated—not least in terms of faster turnaround and cost reduction on steel and vessel time for installation and maintenance of each wind turbine. However, there is untapped potential in focusing on interface standardization to increase the lifetime expectancy and reuse of steel structures from sea fastenings, especially for blades and towers, which are frequently purpose-made for each offshore wind turbine project. Carefully managing our finite natural resources, especially in steel production and consumption, remains critical across industries to further reduce carbon intensity and overall costs. To succeed, we must abandon the outdated 'take, make, consume, and dispose' mentality and move toward an even more circular economy model for optimal resource efficiency. Sea fastenings must be designed for reuse and lifetime optimization across OEMs and transport and installation partners, which would significantly reduce costs both in terms of energy and natural resources and enable faster turnaround at a time when installation vessels are in high demand. We would like to call for a standardization of interface components and updating regulation to ensure the reuse of steel from sea fastenings within the offshore wind industry.
