Wind generators would be very price elastic: if an idle shipyard makes a desperate offer, the whole profitability threshold shifts and the energy market is impossible to completely saturate (worst case you'd have so much energy that it would be economical to synthesize hydrocarbons from thin air, to pump them into the ground for CO2 credits). Also, look at it from the other side: the actors (states) who might be interested in propping up shipyards have very little direct use for generic shipping. Even less if there is a shipping glut (which would typically be just the time when the shipyard would need the propping-up). Conventionally, the only realistic thing a state could do to keep the shipyards in business would be to order some warships. With floating wind, this would change, instead of getting something destructive that will keep costing money once it's there you could get something productive.
