Īs of 2020, the United States Department of Energy is funding two demonstration projects: University of Maine's Aqua Ventus I, which plans to use a semisubmersible floating concrete foundation design and Lake Erie Energy Development Corporation's (LEEDCo's) 20 MW Icebreaker project Principle Power was planning a 30-MW WindFloat project in 2013 using 6-MW Siemens turbines in 366 m of water near Coos Bay, Oregon to be operational in 2017, but the project was cancelled as too costly. In May 2014, the United States Department of Energy chose an offshore wind projects to receive funding. North America’s first floating wind turbine was the 20 kW Volturn US, which was lowered into the Penobscot River in Maine in 2013. In 2019, the University of Delaware and the Danish Energy and Climate Academy jointly opened the first US skills training program for offshore wind energy professionals. Portsmouth Marine Terminal (VA), Port of Baltimore (MD), Artificial Island (NJ) Port of Paulsboro (NJ), South Brooklyn Marine Terminal (NY), Port of Albany–Rensselaer (NY), New Bedford Marine Commerce Terminal (MA), and Salem Harbor (MA) have all been identified as potential offshore wind ports which would support the manufacture of components and staging areas for off-shore wind farms. Several ports are building or converting facilities to handle the large components and manufacturing facilities such as a blade factories are planned. In December 2020, Congress approved a 30% investment tax credit for US offshore wind farms. The Charybdis vessel is under construction in Texas, scheduled for 2023. Two or three US yards have the capacity to build such vessels. To comply with the Jones Act wind turbine installation vessels for $300 million could economically supply a schedule of 4 GW projects over 10 years. The lack of ships of size needed to transport large equipment needed for wind turbines has slowed the develop of offshore wind farms. ports be carried on U.S.-flag ships, constructed in the United States, owned by U.S. Section 27 of the Merchant Marine Act is known as the Jones Act and deals with cabotage ( coastwise trade) and requires that all goods transported by water between U.S. The Merchant Marine Act of 1920 is a United States federal statute that provides for the promotion and maintenance of the American merchant marine. The Bureau of Ocean Energy Management is the federal agency responsible for determining offshore areas where wind farms may be built on the Outer Continental Shelf. The NOAA Coastal Services Center (CSC) has released a cadastre web tool to illustrate suitability of Eastern seaboard areas. Specifically, the Department of Interior approved “wind energy areas” off the coast where projects can move through the regulatory approval process more quickly. In January 2012, a "Smart for the Start" regulatory approach was introduced, designed to expedite the siting process while incorporating strong environmental protections.
