A great article from the BBC, with a startling set of pictures. How soon before we see these rigs in the Gulf o" Maine?
Ships on Legs
By Giancarlo Rinaldi
BBC Scotland
Rising from stormy seas, the giant turbine towers of an offshore wind farm seem almost miraculous to the untrained eye. But how do you put them there?
Most boats do not have legs. But a jack-up barge has six, protruding high into the air when the ship is in transit.
Extending to a length of 48m from the bottom of the ship, and penetrating up to 5m into the sea bed, the "legs" of these ships provide a stable "ground" in a place where there is only roiling water.
