Posters
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.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO180: OWA Design of Offshore Monopiles Including Seismic Interaction with Soil (DONISIS) project
Christina Starost, Associate - Offshore Wind, The Carbon Trust
Abstract
The global renewable energy sector is expanding rapidly, with offshore wind power gaining prominence, especially in regions like the United States and Asia-Pacific (APAC). As the industry grows, particularly in seismic areas, developers face significant challenges in designing earthquake-resistant support structures for offshore wind turbines (OWTs). A key concern is the complexity of monopile (MP) soil interaction, especially in light of designing foundations against dynamic motion amplification, permanent deflections and rotations, or potentially catastrophic failures caused by ground liquefaction. These challenges are critical to address via closing knowledge gaps since the alternative of design overconservatismcan undermine both the sustainability and the economic viability of offshore wind farm construction in seismic regions. The DONISIS research project, led by Delft University of Technology and supported by 17 academic and industry partners, aims to tackle these challenges. Funded through the Carbon Trust's Offshore Wind Accelerator programme as well as public funding of the Dutch research council NWO and industry contributions, DONISIS seeks to enhance understanding of seismic soil-structure interactions in MP-supported OWTs, with a particular focus on non-linear soil-structure interaction including pore water pressure effects. The project is structured into four work packages: (a) improving constitutive sand modelling with focus on seismic behaviour; (b) conducting physical testing on seismically loaded OWTs using geotechnical centrifuge facilities; (c) 3D Finite Element (FE) modelling of seismic OWT-Monopile-soil interactions; and (d) developing accurate and efficient 1D models for seismic analysis of MP-supported OWTs. The knowledge gained from DONISIS will contribute to the creation of a new 1D seismic design model for MP foundations, which aims to be both accurate and computationally efficient. Ultimately, the project aims to establish seismic design recommendations and best practice guidelines for the industry, ensuring the safe and sustainable deployment of offshore wind energy in seismic regions.
