Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

There is no such thing as the optimization of platforms - the foundations for wind turbines are custom designed for each turbines (because, strangely enough, they have to carry serious loads) and mixed used is not recommended.

You could optimize cables, but this is already done by having large wind farms which fully use the capacity of a given cable.

The best place to do a mix of technologies is the grid itself - it is completely inefficient to try to have each producer be a perfectly balanced supplier - better to do the fine tuning of the system at the system-level, where all the individual movements are blended and blunted, and the adaptation effort can be smaller, in aggregate.

Wind power

I was referring to floating platforms which can also be used to support wavebob or other water turbines - which would dampen the yaw of the platform - with the above surface element used to support a wind turbine.  I'm not suggesting trying to balance production at a platform level - merely suggesting that if you have a floating platform already built, you might as well use it both above and below the waterline. Of course you may be right in suggesting a mixed load of wind and wave stresses could require a stronger platform that would be more expensive to build.

Ah Jerome, you marvel. I keep trying to find a succinct formulation, to refute all the nonsense about having to balance at the level of one turbine, one wind farm, one technology. And there you've done it in one beautiful paragraph. These words I'll treasure and propagate, with credit where credit's due:

At, I believe an ARPA-E event, one of the companies was a developing of 'bag' storage -- inflating bags at the bottom of the ocean when there is excess energy to provide stabilization of power supplies. Can't, at the moment, recall the company (have their material somewhere ...).  Clearly, this is something that could be associated with offshore wind facilities. Now, that would be dual use of cables, no?
