Tianjin, March 3 (ZXS) -- The reporter learned from Offshore Oil Engineering Co., Ltd. (hereinafter referred to as "CNOOC Engineering") that on March 26, China's first deep-sea floating wind power platform "CNOOC Guanlan", which is responsible for the general contracting of offshore oil engineering, set sail for the Wenchang sea area of Hainan at the Zhuhai site wharf of the offshore oil project, marking that China's key offshore wind power technology has made significant progress and offshore oil and gas development has taken a key step into the "green power era".

According to reports, the "CNOOC Guanlan" has an installed capacity of 7.25 megawatts, consisting of a floating foundation and a fan, with an overall height of more than 200 meters and a total draft of 11000,30 tons. At the bottom is a triangular floating foundation, assembled from 3 steel structure modules, including 1 side columns and 90 middle column, with an overall side length of nearly 35 meters, a height of about 4000 meters, and a weight of <>,<> tons.

Above the floating foundation is a cylindrical column about 83 meters high, equivalent to a 30-story building, and above the column is equipped with a 260-ton cabin, which can direct the fan to rotate and pitch operations, and is known as the "brain" of the fan. The front of the cabin is an impeller with a diameter of 158 meters, which is known as the "big windmill", and the sweeping area of one rotation is nearly 20000,2 square meters, which is about the size of 7.3 standard football fields, driving three large blades to rotate the generator in the nacelle and generate a steady stream of green electricity.

It is understood that the "CNOOC Guanlan" is China's first floating wind power platform with a working sea area of more than 100 kilometers from the coastline and a water depth of more than 100 meters, and its completion and operation have increased the independent development capacity of China's offshore wind power from less than 50 meters to more than 100 meters, laying a solid foundation for China's wind power development from shallow to deep sea.

"CNOOC Guanlan" will be installed in the offshore oilfield area 136 kilometers away from Wenchang, Hainan, after operation, the annual power generation of the wind turbine will reach 2200 million kilowatt hours, which can meet the electricity demand of 3,1 Chinese a year, and the generated electricity is connected to the offshore oilfield power grid through a 5-kilometer-long dynamic submarine cable for oil and gas production, which can save nearly 1000 million cubic meters of natural gas and reduce carbon dioxide emissions by 2,2 tons per year.
