Siemens Gamesa and Aalborg Uni to Lead Offshore Wind Cost-Cutting Initiative

first_imgSiemens Gamesa and Aalborg University (AAU) in Denmark will lead the new i4Offshore research and development project focused on significantly reducing the cost of offshore wind power. Officially entitled “Integrated Implementation of Industrial Innovations for Offshore Wind Cost Reduction”, the project is supported by a European Union (EU) Horizon 2020 research and innovation programme grant of nearly EUR 20 million.A total of 15 project partners companies are involved in the project in addition to Siemens Gamesa and AAU. They include Universal Foundation A/S, Bladt Industries A/S, Per Aarsleff A/S, Salzgitter AG, Windar Renovables, Dr. Techn. Olav Olsen AS, NKT Cables GmbH & Co KG, SINTEF Ocean, Bureau Veritas Marine & Offshore SA, Maersk Broker K/S, Deugro Danmark A/S, Fred. Olsen Windcarrier, and Technical University of Denmark (DTU).“Siemens Gamesa is committed to reducing the cost of offshore wind energy, and greatly welcomes this grant. Our constant focus on innovation – along with strong partners, customers, and support such as from the EU – enables us to push the industry forward, delivering a lower Levelized Cost of Energy (LCoE) and higher annual energy production. The R&D work we’ll do during this project has clear goals of benefitting our customers, ratepayers, and society-at-large,” said Jesper Moeller, project lead and Senior Specialist in Offshore Technologies at SGRE’s Offshore Business Unit.The i4Offshore project, which is based on classical engineering disciplines such as structural analysis, geotechnical engineering, production and risk analysis, will test a complete installation of a future version of a full-scale Siemens Gamesa offshore turbine. A new 1,000-ton bucket foundation, a steel jacket, a concrete transition piece and a new cable connection is expected to prove that the technology is reliable, and that production, transport, and installation can be done more cost effectively than today.“One of the challenges of offshore wind energy is that the high cost of building offshore wind turbines has necessitated various governmental subsidies to improve the business case. While all forms of industrial power generation receive governmental support, whether from renewable, fossil, or other sources, our project aims at making offshore wind energy even more cost-effective without external financial support,” said Lars Bo Ibsen, Professor at Aalborg University.The project aims to apply the advanced technologies to reduce the Levelized Cost of Energy (LCoE) from offshore wind. But before the project reaches that goal, the various elements must prove that they can be integrated into an overall solution.“We already have a lot of pieces that we know work separately. Now we are in the process of assembling them into a large puzzle, and testing that they work together. As this is proven, we look to demonstrate to customers, banks, and investors that offshore wind makes even more financial and environmental sense for the future,” Ibsen said.Furthermore, the project will test installation solutions with a minimal environmental footprint. The bucket foundation can be installed virtually noise-free as installation takes place via suctioning into the seabed instead of being hammered down from above, Siemens Ggamesa said.“Using a suction-bucket foundation benefits whales and other undersea life by eliminating the soundwaves which hammering causes. Also, once the wind turbine has exhausted its many years of operational life, the suction buckets, jacket foundation, and transition piece can be decommissioned and removed relatively easily. The materials, including steel, concrete and cables, can be re-used in a highly resource-efficient manner,” said Moeller.last_img
