Description
This dataset represents the component replacement, recycling, and disposal of a single offshore wind turbine with a rated power of >=5 MW during its technical service life. For component replacement services during wind power operation, it is assumed that each turbine replaces one blade and 15% of generator components within its technical service life, and the distance from the port to the replacement site is the weighted average offshore distance of 82 wind farms. Therefore, the main raw materials consumed are wind turbine components and blades, while the primary energy consumption is the electricity used for replacement. For the end-of-life treatment of wind turbine components, it is assumed that 90% of metal materials (such as steel, iron, aluminum, and copper) and wood in the wind turbine structure (including the tower) are recovered; resin, glass fiber, plastic, rubber, and other materials are incinerated; and other materials are disposed of through landfilling. The technical service life of the wind turbine is consistent with that of the wind farm, which is set in accordance with official specifications and standards: the technical service life of onshore wind farms is 20 years, and that of offshore wind farms is 25 years. The data are mainly sourced from published literature and empirical values.
