Potential for floating wind energy is going to depend whether the current cost disadvantages can be overcome by the development of innovative solutions to constructions and installation
to Develop ResourceOffshore wind energy calls for a broad-based, focused, coordinated approach to planning, research and development, and policy development.

Many Technology Needs
Many Stakeholders
• A principal focus is to broaden the wind resource potential through exploration of deep water and far offshore technologies.
• Goal: To overcome the barriers to generating and delivering electricity from U.S. offshore wind farms at a competitive cost by the beginning of the next decade.
• Consult with key parties to identify key issues and obstacles to a sustainable offshore wind industry.
• Develop a Framework that identifies opportunities to take advantage of and barriers to overcome that will lead to successful offshore wind development in the US.
• Design a Organizational Development Plan that recommends the organizational structure, funding levels and sources, and human resources necessary to implement the Framework and realize its potential.
Collaborative ParticipantsGovernment• MMS - lead regulatory agency
Coast Guard and Army Corps of Engineers
EPA, NOAA, Fish and Wildlife Service• Department of Energy • State and Local Jurisdictions
Industry• Wind manufacturers and developers• Offshore oil/gas, general marine• Utility sector
Research Community• National Laboratories• University and research institutes• International liaison / coordination
Framework DevelopedEarly 2004: Massachusetts Technology Collaborative, General Electric, DOE agreed to explore collaboration for development of U.S. offshore wind energy Early pilot research Developed “Framework document” based on
broad stakeholder input
Mid 2005: Framework released addresses challenges and outlines for action: Technology Development Environmental Compatibility Economic and Financial Viability Regulation and Governmental Policies Leadership Coordination
