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!
PO154: Multi-Concept Substructure (MCS)
Stefano Vaccarone, CEng. MRina, Offshore Wind Structural Engineer, TotalEnergies
Abstract
Offshore wind turbines are getting larger and larger and being installed in deeper and deeper waters. For such big turbines and depths, monopiles are becoming massive and too heavy, difficult to fabricate and install, with subsequent impacts in projects' economics and planning. Although Steel truss jackets fabrication is feasible, their dimensions are challenging for transport and installation, and would reach the maximum capacity of the supply chain in terms of fabrication time. Gravity Based Substructures' weight, size and amount of ballast are also challenging. The Multi-Concept Substructure (MCS) is a new concept that combines the benefits of jackets, monopiles and GBS, unlocking the use of fixed offshore wind foundations for large turbines and deep waters. The MCS is composed by: * a steel truss jacket structure, to be placed on the seabed, * a monopile, inserted in the jacket * a gravity based component, solid ballast, poured into the truss structure This innovative concept won't require significant investments, as it fits well within the current fabrication capabilities of the supply chain, as well as within the standard installation capabilities of heavy lift vessels. Given the uneasy reduction of LCOE for floating offshore wind, this technology has the ambition of being the missing link between fixed and floating offshore substructures and provide a solution for water depths still unreachable for traditional designs.
