The U.S. has no floating wind farms on the west coast yet, but a project has just been approved by the government for five floating 6Mw turbines (with a cement ballast system) about 15 miles off the Oregon shore.
Portugal already employs a floating turbine. There are fewer regulations involved since it is not bolted to the seabed, and a 20% higher cost per mega-watt hour.
No resolution yet to the ongoing question of whether there is a self-sustaining, competitive business model for wind energy. I keep watching for it.
