That image has been posted here before. None of them seem to have been installed yet, but it will happen real soon now (unless somebody missed a trick in the design process).

One was installed this year at Rotterdam, and a 2nd
one is going up in the UK. Quite a few are on order
for offshore use in Maryland and New Jersey.

Just considering the blade length the distance to the horizon for one of these beasts is 48 km or 30 miles. I understand they were only permitted off the coast of Ocean City, MD if they were not visible from the shore. At that distance the water is around 120 feet deep. That's so insignificant compared to the 3 km waters oil rigs operate in.

aren't those deep water oil rigs actively held in position with thrusters?

But is it delivering power into the grid?

Getting it up to the top of it's pylon may count as "installation" for marketing purposes, but you tend not to get paid until the unit has delivered power to the grid.

https://renewablesnow.com/news/ge-installs-12-mw-wind-turbine-prototype-in-rotterdam-673053/

"Installed at a site owned by Sif Holding NV (AMS:SIFG) in Maasvlakte, the Haliade-X prototype will produce data needed for the issuance of a Type Certificate next year, GE said."

So a prototype in place for testing, but no type certificate yet (whatever that might be).


> and a 2nd one is going up in the UK.

That's not installed.

Quite a few are on order
for offshore use in Maryland and New Jersey.

This has also been mentioned before.

Wind turbines get a type rating so that countries (buyers) considering
their use can make decisions about what class to get.

I'm sure they're going to run it at full power into
the grid, at least for some time, but I don't know
its long term future. It has already produced its
first power, reported on 7 November 2019.

news: GE has sent a second blade, manufactured by
its subsidiary, LM Wind Power, for fatigue testing
at the Massachusetts Clean Energy Centre in Boston.
That's in Charlestoen, short distance from us. I'm
impressed, I didn't know it could handle 107-meter
blades, they had earlier mentioned a 90 meter limit.

Uh huh. What storm wind speeds are they rated for?

22,000 miles per hour!

What? Do you think they are going to be easily damaged???

That is the highest class.

Related to the blades. Kind of hard to make them so sturdy, yet
still be light in weight. Especially at over a hundred yards each.

Better than big wooden windmills though, I suppose.

It says class I has gusts of 70m/s, which is 156mph, I
think. What's the significance of the B after the I?

Still hunting.

I think it may be a GE thing. But the declaration makes it sound
like an international agreed upon norm, so there must be an
orginization somewhere that is keeping tabs.

IEC/EN 61400 specifies A-B-C to be high-medium-low turbulence and has
models for normal, extreme turbulence and wind speed characteristics.

Funny thing is that at least the old version (2005) I have states that
classes IA-IIIC are not intended to cover offshore or tropical storms,
but require class S (for Special) design. I'm sure there's been a lot of
progress on this field during the last 14 years and the modern standards
cover offshort wind parks as normal cases.

I dunno. Let's face it, we learn from our failures. How many off shore installations have been damaged by tropical storms?

I had a structural engineer look at a house I am buying and his signature on email reads, "Anyone can make a building stand up, it takes an engineer to make it barely stand up".

That pretty much says it all.
