Danes Talk 62 MW Offshore Wind Turbines For North Sea Energy Island
The title of this post, is the same as that of this article on Offshore Energy.
The Danes may talk 62 MW, but that four times larger than one of the biggest today, that I wrote about in Vestas 15 MW Prototype Turbine Produces First Power.
This paragraph says a bit more about the 62 MW turbine.
According to the DEA’s framework document for the draft plan for the strategic environmental assessment (SEA), this could be a 500-metre-tall wind turbine with a rotor diameter of 480 metres and a capacity of up to 62 MW.
This turbine is bigger in terms of capacity, than than some whole farms.

Theres no ground mounted crane that can reach that high. Liebherr can currently do 236m with a crawler crane. Going to have come up with a new way of building them perhaps jacking up the last 250m like tower cranes do?

With a 480 metre rotor, the nacelle must be about 270 metres above the water. Supposing the assembly crane was mounted on a dock with very deep water. The float which would be like a very long monopile, would be built horizontally and turned vertically in a similar way to that I proposed for Balaena Structures oil and gas platform. It would then be moved alongside the dock and ballasted with sea water so that it was the right height for the nacelle fitment. After that the ballast in the monopile would be adjusted so that it was the right height for blade attachment. It would then be towed into position vertically. The blades might get a bit wet, but they should be able to stand up to heavy rain at sea.

One of the problems of wind turbine blade performance is that of erosion caused over time by heavy rain.

That could surely be solved by better materials!
