The coastlines of the United States, both eastern and western, and the Gulf of Mexico have excellent wind resources. The wind resources are near major population areas whereby power can be generated having a minimum distance to the end user. The continental shelves that surround the U.S. allow placement of wind power systems in both state and federally controlled waters. Employing the technologies generated for oil and gas offshore operations as well as the advancements of large megawatt class generators, will allow great flexibility to provide efficient offshore wind farms. The choice of support of the platform is discussed in the paper. The means and methods for installation of the platform, including cost comparisons are also included in this paper. Wind farms have an expected useful life of 25 to 30 years. This paper discusses the design of the wind farm to accommodate the necessary maintenance required during the useful life of the wind farm. The cost of offshore maintenance is also illustrated in comparison to long-term power purchase agreements. This report illustrates the types of structures, installation costs and maintenance costs which the wind farm developer will be subjected to. The future of offshore technology is discussed regarding the use of ocean bottom conditions to be the most efficient and reliable type of renewable energy.
