True E-P. But these structures aren't much more than 36" or 42" rolled steel pipes. A whole lot cheaper than building a spar (which also needs surface support vessels to be anchored). When you figure a commercial wind farm might need 50 to 100 such installations it could add up to a big cost differential.
Spar or Seahorse, I wonder what the risk from iceburgs moght be up there. I know that was a big factor in the design of the Hibernia platform of Canada many years ago.
AGCC seems to be taking care of that...
I suspect a tethered platform would be more survivable than a fixed one. If an iceberg ran over the top of it and broke the tethers, it would just float off (assuming bouyancy wasn't compromised). If the platform had an EPIRB (or similar) it could be tracked and recovered.
