Found these some time ago. Definitely worth thinking about...
There are three main types of floating platforms for wind turbines. The three main types off platforms are the Semi-submersibles (Semi-Subs), the Tension Leg Platforms (TLPs) and the Spar Buoys (a spar is a mast or a stout pole).
Several alternatives have been tried to these three main types, including one by MUPFLOST, the CARROT “true” SPAR (Single Point of Anchorage Reservoir), but, so far, none of these alternatives revealed to be viable. The patent (PAT 107474 H) was already accepted by the Portuguese Patent Office and presently is at the public consultation phase.

and...
The high total buoyancy of the floating platform is mainly achieved by the large volume of the three concrete floaters. These floaters have a spherical shape in order to maximize their volume while minimizing the area of wall needed. The bottom of the floaters is flat to facilitate the stand still of the structure in the construction yard, or while grounded in a harbor or in shallow waters. This flat surface is also needed to make the transition between the external spherical shape of the floater and the interior conical shape of the floater hole. This conical hole allows the moorings to cross the floater while allowing them also to sway. The oscillation of the mooring cables is essential to the platform stabilization.

and their variable ballast anchor...
The anchors of the platform are also built with reinforced-concrete. Like in the floaters, the mooring cables also cross the anchor using a hole made on it, so that they may connect to the anchors base. This helps to ensure that most of the anchor structure is compressed. These holes are covered by simple PVC covers in order to prevent the deposition of sediments inside the anchors.
