Looking at the designs presented for floating oceanic wind turbine bases shows, that there is a need to have as much stability as possible, while
moving in response to wave action and tides.<p>By default, all power generating equipment is 100% duty cycle , 24/7/365. For fixed land based machines the various loads and environmental wear
conditions are more or less predictable. Marine instalations on the other hand, are notorious for destroying anything and everything, very especialy
anything with moving parts, due to all of the land based factors, plus operating on an unpredictable moving platform.
Total failure of the entire structure can be initiated by the failure of any one of many bearings/joints where movement between components takes place,deep underwater.
Inspection becomes a challenge and service at sea impossible.
The many failures of underwater tidal generators
bears testimony to the dificulties and challenges.
