It depends on the soil condition. The Atlantic is still very shallow 15 miles offshore, whereas the Pacific can be significant deeper. The shallower the easier.

Generally yes, but the problem is not the technology; it's our insane and unstoppable demand for energy. Also, it doesn't work to produce electricity offshore Florida and transmit it 2,000 miles to Minnesota.

Some blades may break, it may cause excessive stress to the tower, perhaps the foundation, but if they fall, nobody will be hurt and it is easily salvable.

I can't give details, but slightly higher installation cost than land-based, with perhaps less wear and tear on the clutch and gearbox because of the steadier wind regime.

About 30 years.
