Thanks for that information, Jim S. I wasn't exactly sure how the floating system works but that makes a lot of sense. I always thought the idea of a "floating" structure was a bit of a misnomer and there had to be some anchorage in there somewhere! So it is true.

@a.saji: It is obvious to most, that the maintenance costs of offshore devices like this will be higher than the terrestrial based versions.  Of course, they may be offset by the fact that no costs at all will be incurred by land rental or purchase.  I personally would wonder if wind turbines in the open ocean would be better served using Darious rotors, for reduced costs of maintenance and safety.  Terrestrial based turbines with the generators at the top are maintained by people climbing them and doing the maintenance.  This might be easier with the Darius rotor in the open ocean, because the generator and gears are at the bottom.  This would also lower thecenter of gravity, making it more stable on a floating platform.

@apresher: In anywhere maintenance cost is considered as high most of the time.

From past articles I've done, my understanding from suppliers is that offshore turbines (especially in North America) isn't gaining ground like it is in Europe and other places where available land is a factor. Maintenance costs are high for offshore, for example.

I can see the platform surviving a huricane, but not so sure about the composites.  If they build them like the oil rigs, maybe they will only need to replace the blades after big (cat 2+) storms.

Thanks, Elizabeth, for this story. The concrete-composite combo makes a lot of sense. We've covered the use of corrosion-free composites used in pontoons and docks, and combining it with concrete clearly gives stability and weight where needed, as well as lower cost.

They are all anchored. The Floating type are tethered to the bottom through cables and anchors arranged around it. The others are tall enough that they are towed out floating and then sank so that the bottom is firmly on the sea bed. There have been some tv programs on how it was done.

Sounds like those platforms would be a good example to those deploying turbines offshore. I think the floating idea is a good one but anchorage may be a better option, especially to handle severe storms. I suppose it wil be a trial and error situation as some of these early platforms in the U.S. are deployed to see what works.

Hi, Capt. Ron, yes you read correctly. In the story link I posted in my previous comment it says the proposed turbines are taller than the Washington Monument. I suppose they will be built solidly enough to withstand the perfect storm, but I guess it would take those type of conditions to find out what happens.
