A wind turbine blade gets maneuvered through tight bends by a special transport vehicle. At about 100 meters in length, the giant blade must be lifted and rotated to clear obstacles. #WindPower #Engineering #China

China completes installation of world's largest single-unit floating offshore wind turbine The world's largest single-unit 16-megawatt floating offshore wind turbine "Three Gorges Pilot" was installed on Saturday in waters off Yangjiang, south China's Guangdong Province. The 16-megawatt floating offshore wind turbine consists of three parts, namely a 16 mw ultra-large capacity wind turbine, a semi-submersible floating platform, and a new mooring system. With a maximum tip height exceeding 270 meters, the wind turbine rotor has a diameter of 252 meters, with a swept area equivalent to seven standard football fields. Unlike traditional fixed-bottom turbines that are physically connected to the seabed, it is installed on a semi-submersible floating platform measuring 80.82 meters long, 91 meters wide, and with a displacement of 24,100 tons. The platform is secured through nine suction anchors, combined with domestically produced high-performance polyester fiber cables and anchor chains for seabed mooring and positioning. "To deal with the harsh sea conditions, our team has developed and applied a new mooring system, a dynamic monitoring system, an active ballast system, and 66 kV dynamic submarine cables for the first time in China," said Pan Hongguan, an offshore wind power engineer from Guangdong Branch of China Three Gorges Corporation (CTG). According to Pan, the new mooring system combines polyester cable and anchor chain, which is like adding a "spring" to the middle of the system, to deliver superior mechanical performance. The "Three Gorges Pilot" wind turbine previously completed its integrated assembly at Tieshan Port in Beihai of south China's Guangxi Zhuang Autonomous Region. It arrived at its target sea area located more than 70 kilometers off the coast of Yangjiang after a long-distance towed voyage across the Qiongzhou Strait which connects South China's island province of Hainan with Guangdong Province on the mainland. After being put into operation, the wind turbine is expected to generate approximately 44.65 million kilowatt-hours of clean energy annually, enough to meet the annual electricity demand of 24,000 households.

The Department of the Environment didn’t answer the question so I will. And I quote: “Bisphenol A is a highly toxic synthetic organic compound used in the epoxy resins of turbine blades. Epoxy resins contain 30-40 per cent bisphenol A and turbine blades are the largest global consumer of epoxy resins. The annual global production of bisphenol A is about 2 billion kilograms and is increasing because the spearing of the environment with wind turbines is today’s fad. Bisphenol A is an endocrine disrupter that has been linked to about 80 diseases including cancers and reproductive disorders. It is lethal for young children. In 2012, the World Health Organisation warned about the potentially carcinogenic properties of endocrine disrupters and concluded that they pose a global threat to public health. The European Food Safety Authority has massively reduced by 1,000 times the dietary intake of bisphenol A to one hundred millionth of a gram per kilogram of body weight per day. All this is public record information which the wind industry must know. The leading edges of turbine blades shed fine dust and blade edges only have a 5-year guarantee. Each blade sheds a minimum of 0.2 to 2.5 grams of bisphenol A in dust per year. This dust is spread wide and far by wind. If one gram of bisphenol A gets into dam waters, 10 million litres of water are rendered unusable. Over the life of a turbine, this equates to pollution of half a trillion litres of water per turbine. This is real pollution, not the alleged pollution of carbon dioxide, the gas of life. This dust from eroding blades has covered large areas of our planet and bisphenol A is leaching into soils and waterways. This is a toxic time-bomb.” Quote from: #auspol
