It is reported, a British companies are beginning to design a large offshore wind generators, its wingspan length can reach 275m,wind  power generation capacity will be common wind turbine generator three times. In present advocate green energy trends, Britain, the United States and Norway’s engineers are a giant wind turbine generator competition. British Arup company design of this kind of sea surface, build new turbine generator (Aerogenerator X), extracting 10 megawatts (mw) and its huge machine measure is twice as common type, believe global energy market will because of the new generator and produce a change.

Leaf wingspan 275m, this simulation rotating sycamores leaves design inspiration comes from the float type oil platform technology. In the technology leading Arup engineering company, and by Rolls-Royce, shell and BP, several blue-chip companies funded academic association cooperation, carries on the wind generator meticulous of design, this wind-driven generator for axial rotation, leaf wingspan can reach 275m. Prediction through 2 years of experiment, 1 units will be built in 2013 ~ 2014. But Britain designer team, including the design of Eden project of lattice liam, still have to XiaoJianZhu firm with other group of fierce competition. Earlier this year and the us department of energy subordinate of renewable energy laboratory close relationship of American wind power company announced that they will plan Clipper in England northeast build called “Great Britain” 10 mw wind turbine generator.
The traditional wind turbines to scaling up is the current British pop practice, the colossus will be fixed on the sea floor, well above the waves about 600 feet. That if the Clipper in technology and feasible in economy of words, each pump unit in the 25 years of life span generated electricity, can supply 5000 ~ 10,000 family use, equivalent to two million barrels of oil generated energy. Meanwhile Norway’s Sway company plans to build a giant floating type turbine, such turbines directly connected to a hundred meters deep sea bed is called “the mast anchor points.” A European union-sponsored extensive investigate program also small wind turbines manufacture 8 ~ 10 mw turbine. In the United States and Danish some companies, the ongoing 9 mw unit extensive hair work. All these design of full size model will be completed within three years.

British cranfield university offshore project director phil lattice Brennan said: a splendid intense athletic contest was going on. The competition winner will have the opportunity to achieve global offshore wind turbines market dominion, Britain in offshore wind power generation may start “, but with some 40 years of gas oil drilling experience, we still have the opportunity to lead the world. New wind turbines in half an immersion type is based on the petroleum platform technology to build, and no traditional wind turbines in the weight limit. A new design of turbine its height is along with the level of traditional turbines half. He added that this technology can create more outspread, 20 mw or greater wind turbine generator. At present already installed the largest wind turbine generator power rating of about three megawatts (mw). In contrast to hundreds of megabytes already coal-fired power plants, the level of about 180 of this new wind turbine units, just north of Scotland is equivalent to a coal-fired power stations al county of capacity. The engineer consider whether wind power line and the key is that it build scale.
The traditional wind turbines size doubled, theoretically can produce four times the wind, but meanwhile wind turbines weight and cost also will increase by eight times. According to introducing, due to the sea can receive nobegining wind at sea transportation and large equipment installation is more convenient also, and the public are rare, consequently offshore wind power against widely viewed as renewable energy in the future. On land huge hoisting equipment and leaf transportation often need to travelling, and plan approved often were needed years. But so far offshore installation of the turbine than terrestrial WTG cost will be expensive out three to five into, and maintain a difficult also vulnerable to corrosion.

An estimated offshore wind power market every year there will be billions dollars growth. Last year the European wind energy association expects European offshore wind installed capacity, will from today’s 2000 megawatts growth in 2030 150 thousand megawatts above. Although Britain without building large wind place must highland and space, but in 2008 Britain has in offshore wind power generation in Denmark, and beyond the installed capacity to 330 lead the world. Besides Britain has also developed a remarkable foresight small wind generators development wind resources planning, they expect in 2012 of offshore wind hair capacity up to 12 thousand megawatts (mw). This is equivalent to install the 2500 elevators the biggest 5 mw unit. British greenpeace’s director John ShuWen said: “we demand for energy will hope on this, but the point is that the British government cannot in order to obtain short-term interests and budget cuts to hinder the development of offshore wind power.”
