What are wind turbines?

In 2009, Siemens built the world's first prototype floating wind turbine in Norwegian waters, with an installed capacity of 2.3 MW. The small wind turbine, initially designed to have a lifespan of 5 years, still operates offshore, providing clean energy to the Norwegian power grid. Today, Siemens is building the world's first floating wind farm in the sea, 25 kilometers from Peterhead, Scotland. There will be a total of six 6 MW Siemens wind turbines and it is expected to be completed by the end of 2017. By then, this wind farm will be able to provide clean energy to 20,000 homes. For offshore floating power plants, we believe they can be applied to sea areas with water depths up to 700 meters. The sea areas covered by this depth will include the west coast of the United States, the east coast of Japan, and the sea regions of Spain, Portugal, and France. When the wind speed is ttoo fast, generally greater than 25 meters/second, the wind turbine activates protection mode. It stops and the blades become paddled to reduce wind resistance. At the same time, the cabin is made of high-strength steel to minimize the possibility of strong winds lifting the cabin cover. In addition, Siemens blades also feature a special technical aeroelastic blade. For example, we let the wind turbine blades imitate reeds. When the wind blows, the blades can deform and vibrate like reeds to reduce the direct impact of strong winds on the blades. In addition to dealing with typhoons, another enemy is lightning. After all, offshore wind turbines are essentially the highlight of the nearby sea. They are also the most likely to be struck by lightning. We have compiled statistics between 2003 and 2010, 72 wind turbines at an offshore wind farm in Denmark suffered a totalof 310 lightning strikes. Therefore, a reliable lightning protection package is also essential. Because when the water depth exceeds 50-60 meters, the price of underwater foundation installation becomes extremely high, so using floating fans will significantly reduce costs. Additionally, installing offshore wind turbines is a complicated affair. Not only do you have to first install the foundation, the tower and the nacelle, but you also have to install the blades one by one. Additionally, the facility has extremely high requirements for the marine environment, and work must be stopped in the event of bad weather conditions. The cost of construction and installation of offshore wind turbines is therefore very high. However, if floating wind turbines are used, they can be pre-installed around the dock and then transported to designated sea areas by tugboats, which canSignificantly reduce installation costs and time.
