Giant turbines the size of jumbo jets bobbing on the North Sea may soon become as common off Norway as oil and gas platforms.

Offshore turbines can be twice as powerful as land-based units due to stronger, more sustained winds at sea.
Out of sight from the coast, such wind farms could use modified, more efficient turbines because limiting noise, a key concern for land-based wind farms, is not as critical offshore.
The technology is not tested and costly offshore repairs could quickly drive up costs, analysts say.
