Abstract
purpose of the project was to optimize the TetraSpar floating offshore wind turbine (FOWT) foundation for installation. The project was a collaboration between Aalborg University, Stiesdal Offshore Technologies, DIS and Siemens Gamesa Renewable Energy over a period of four years from 2017 to 2021. The expected result of the project was an improved TetraSpar concept composed of a hydrodynamically and structurally optimized foundation, an innovative mooring solution, and specification of a complete, safe and cost-efficient set of marine operations.
The project succeeded in reaching the desired results. The TetraSpar-concept was optimized hydrodynamically and structurally, and the mooring system was designed with innovative elements. The developed assembly methods proved the commercial benefits of the concept and during summer 2021, the foundation completed its assembly using traditional materiel and workforce, after being manufactured at and transported by existing facilities and infrastructure. The project, furthermore, investigated and formed initial experience in innovative mooring and O&M concept for future projects.
As a result, the TetraSpar project has built experience and knowledge in methods within design, fabrication, assembly and installation of FOWTs, which will be applied further in the future market and next generation of offshore wind turbines.
