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!
PO324: Offshore 690 MPa heavy gauge steel plates with low carbon footprint required in modern wind turbine installation vessels
David Quidort, Product Development & Support, ArcelorMittal
Abstract
The demand for modern wind turbine installation vessels (WTIVs) to install large offshore wind farms has recently increased due to the number of active large-scale offshore wind projects and the ever-increasing output power of wind turbines. Jack-up racks used for the legs of WTIVs require stronger teeth to withstand the enhanced wear and fatigue caused by the higher frequency of up and down operations compared to classical O&G drilling platforms. This application specifies high-strength offshore structural steel with a minimum yield stress of 690 MPa and thickness up to 250 mm thickness. For such heavy rack plates, maintaining consistent mechanical properties and low-temperature impact toughness across the whole thickness while ensuring good welding and flame cutting behavior during fabrication is anything but trivial. This paper will detail the key features of 210 mm and 250 mm thick base metal plates recently produced by Industeel in France for the construction of different WTIVs, contributing to Europe's leadership in the offshore wind industry. Helping offshore wind projects companies to control their Scope 3 emissions, plates are manufactured from recycled steel in an electric arc furnace, allowing a substantial reduction in CO2 emissions compared to conventional steels produced via the blast furnace route. The low carbon footprint of the product will also be highlighted.
