New York Bight - Wind Energy Areas at Sea

Meanwhile:
Massachusetts’ Vineyard Wind is finally approved [1].
The new $3bn project will be over 20 times larger than anything built in the US, and could see up to 84 turbines, offshore from Martha’s Vineyard, near Cape Cod, Massachusetts.

YouTube magically showed me a video, for some reason, I really would like to know their algorithm, about the erosion of the blades on wind turbines.

The edges of the blades start to erode over time and can fall apart if not fixed. The erosion is caused by the salt and sand in the air. Surprising the amount of damage that was done by wee particles.

That is why composite propellers for aircraft usually have thin stainless steel leading edges epoxied on.
Best wishes all.

Glad you said that because that is what I was thinking, why don't they build stainless steel into the blade edges? Seems like a "simple" solution to the problem.

I think because te blades flex too much, I don't know of a stainless alloy that can take that. Hopefully someone else can chime in on that.
Best wishes all.

Huge swathes of ocean used to be out of bounds for wind turbines, as their foundations could only be built in depths of up to 60m.
Not anymore.

A number of companies are developing innovative floating offshore wind platforms, for use in deep waters*.
Four kinds of floating platforms are: spar-buoy, tension leg platform, semi-submersible, and barge.
About 80% of projects plan to use semi-submersible platforms.

In 2022, DOE launched an Energy Earthshot™ to reduce the cost of floating offshore wind, in deep waters, far from shore, 75% by 2035.

Among the advantages of floating offshore wind are the potentially low environmental impact, and the ease of manufacture and installation, as the floating turbines and platforms can be built, and assembled, on land, and then towed to the offshore installation site.
In addition, they can take advantage of the strong winds, blowing in the deeper areas, where it reaches a higher, and more constant speed, due to the lack of barriers, which improves energy efficiency.

* The bulk of the USA’s offshore wind resources [about two-thirds], are in areas where the water is so deep, that conventional foundations [large steel piles, or lattice structures, fixed to the seabed] are not practical.
