Project objective

Offshore wind business competitiveness is strongly related to substructures and offshore logistics. DEMOGRAVI3 addresses these areas through a very promising solution called GRAVI3. GRAVI3 is an innovative hybrid steel-concrete offshore sub-structure for transitional water depths between 35 and 60m. It will sustainably reduce the levelized cost of energy by up to 15% by combining the following vectors: - Using three concrete caissons, with water ballast, instead of more complex and costly steel solutions and anchoring systems - Using a smaller steel structure - Performing all construction and assembly onshore and towing the complete unit to the site where it is submerged with an innovative and robust method. - Preventing the use of heavy lift vessels and reducing the level of complexity and risk of offshore operations. GRAVI3 has undergone the typical technology development process and is presently at TRL5. The logical next steps is the demonstration at full scale in real operational conditions. Thus, the project fits perfectly to the addressed Call for Proposals as the project will support technology development and bring the technology close to market readiness. The proposed project will design, engineer, build, assemble, transport, install and demonstrate a full scale foundation, equipped with a 2 MW offshore wind turbine, in a consented and grid connected demonstration site. Additionally, the project will undertake further technology development for improved design and perform an in depth evaluation of the technology’s future industrialization, competitiveness and bankability. The core partners are committed to bring the GRAVI3 technology to market intending to 1) form a company with the objective to commercialize the GRAVI3 technology; 2) prepare themselves to take on important segments of the industrial value chain which will be put in place to move the GRAVI3 product forward; 3) foster the use of the technology, namely in the wind farms they are developing.
