I have absolutely no clue as to how they yaw the thing. A 1° yaw error with the wind is like 2-3% efficiency penalty, and a penalty on durability.

- dx034 9y agoI guess as with most turbines. Most will remain fixed, only the upper part with generator will rotate. This shouldn't work different to conventional turbines.
- nraynaud 9y agoHow do they rotationally fix the floating barge? Think of the tides.
- cr1895 9y agoIf we're talking about the spar-type hywind base in the video: Its catenary mooring system resists rotation of the turbine hull. How much so, I can't say. I suspect that by far the greatest rotational forces exerted on the structure are coming from wind, not from water, and these would result in low-frequency motions that could be countered by the already rotating nacelle. The smooth spar structure means that surface waves and currents don't result in huge moments about vertical.
