Most boats do not have legs. But a jack-up barge has six, protruding high into the air when the ship is in transit.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.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.

If government targets are to be met, the UK could have as many as 7,000 offshore wind turbines by 2020. In the process, it would increase the amount of energy produced by that means about 60-fold.If government targets are to be met, the UK could have as many as 7,000 offshore wind turbines by 2020.

I was part of Global marine and took part in the installation and commissioning of the Worlds first commercial offshore windfarm at Horns Rev, 11 miles off the coast of Denmark. Then we used a 'dumb' jack up barge (it had to be towed) The problems we encountered during installation were setting the project timelines back, weather and the fact that it was a learning curve for all. This vessel certainly makes life safer and easier for all in a hostile environment.Robert, CumbriaI was part of Global marine and took part in the installation and commissioning of the Worlds first commercial offshore windfarm at Horns Rev, 11 miles off the coast of Denmark.

I think this is a wonderful piece of engineering that will deliver a much needed boost to our cleaner, more greener energy needs.What still puzzles me is the amount of opposition to these offshore farms. I cannot see how the wildlife could be severely impacted and if it is then surely the impact is less than the longer term prospects of climate change.It makes me wonder if it is the same people campaigning against these wind farms, who also demand less use of the Coal, Gas and Nuclear power stations. No doubt they would also find a complaint about a safe and efficient Fission Reactor when the technology is introducedJames Doyle, Leicester, UKI think this is a wonderful piece of engineering that will deliver a much needed boost to our cleaner, more greener energy needs.What still puzzles me is the amount of opposition to these offshore farms.

Amazing, but there's really nothing fundamentally new about these vessels. The offshore oil and gas industry has been using jack-up rigs for many years in relatively shallow water. The principle is the same and I'll warrant that most of the technology for these vessels comes from the offshore hydrocarbon industry. Interesting, isn't it, how the technology developed in one energy industry is being used in another energy industry that seeks to supplant (or at least complement) the first?John Levins, Rome, Italy (ex of Kuwait)Amazing, but there's really nothing fundamentally new about these vessels.

I see lots of comments about how it would be great to build such 'wonders' in the UK. I've got news for you: jack-up barges were built in the clyde for 30 years..at the old John Brown Shipyard at Clydebank. I should know - I surveyed them and took them down the river for most of these years. This Chinese one is purpose built and is self-propelled...more like a ship with legs than a barge but the principal is the same. Former jack-ups could not be used as it would be too costly to modify them and remove the drilling derrick. This one is a 'mini'. Some of the Clyde-built ones were very big indeed having legs over 500 ft. in length. Incidentally; a maximum penetration of 5 foot is a dream unless the wind turbines are situated in one special location vis-a-vis sea bed formation. "I know 'cause I was there".Capt.

Why not put the turbines on the sea bed? Sea water is over 800 times denser than air and a non-compressible medium, so an 8 knot tidal current is the equivalent of a 390 km/hr wind speed.

The energy needed to build these barges and turbines is probably comparable to the energy needed to build and decommission conventional power stations. With a tiny fraction of the carbon emissions required to produce the energy. But I'm not an expert so cannot definitely comment. Similarly, those who complain about the relatively high cost of wind power should consider that this will almost certainly decrease as the technology becomes more standard and less novel, a la computers in the last thirty years and cars over the last century.
