VolturnUS 1:8 Floating Offshore Wind Turbine

Orono, ME

The launch of VolturnUS 1:8 celebrates an important milestone in the development of a cost-effective, job-creating, innovative U.S. offshore wind technology.

Scope of Work

Cianbro worked with the Advanced Structures and Composites Center at the University of Maine to develop the first grid-connected floating offshore wind turbine. The turbine, named VolturnUS 1:8, is the first offshore wind turbine to be deployed off the coast of the United States/Maine and the first concrete floating wind turbine in the world.

Project Details

  • The VolturnUS technology is the culmination of over five years of collaborative research and development conducted by the UMaine Composites Center, as the Manager of the DeepCwind Consortium. The DeepCwind Consortium Research Program is a unique public-private partnership funded by the Department of Energy, the National Science Foundation – Partnerships for Innovation, the Maine Technology Institute, the State of Maine, the University of Maine, and over 30 industrial partners
  • The 65 feet tall turbine prototype is a one-eight-scale version of a 6 mw, 423 feet rotor diameter design. It is the first floating turbine of its kind in the world, using advanced material systems with a unique floating hull and tower design
  • Data acquired during the 2013 deployments off Castine, Maine, was used to optimize the design of UMaine’s patent-pending VolturnUS floating wind turbine system
  • The program goal is to reduce the cost of offshore wind to 10 cents/kWh by 2020, in order to compete with other forms of electricity generation without subsidies
