Description
This dataset represents the foundation construction and equipment installation for a single offshore wind turbine unit with a rated power of >=4, <5 MW. During the construction and installation stage, the main material inputs include concrete, reinforcing steel, structural steel, sacrificial aluminum alloy anodes, rubber fenders, and sandbags, while energy inputs mainly consist of diesel fuel and water used for construction and installation activities. In the decommissioning and end-of-life treatment stage, it is assumed that metallic materials, including reinforcing steel, steel, iron, aluminum, and copper, are recovered at a rate of 90%. Materials such as resin and rubber are treated by incineration, while other materials are disposed of via landfilling. The data are primarily derived from publicly available literature and empirical experience.
Activity Description
The process boundary involves raw material preparation, on-site construction and installation, as well as dismantling, recycling, and disposal phases, but excludes the operation and maintenance phase.

Technology comment
This dataset primarily describes the foundation and equipment installation of offshore wind turbines. It is assumed that all construction materials and equipment are processed onshore and then transported by sea to the offshore work area for construction and assembly, with the transportation distance taken as the weighted average offshore distance of 82 wind farms. During the construction and installation stage, the main material inputs include concrete, steel, copper, aluminum, and resin, while energy consumption primarily consists of electricity used for construction and installation activities. Land occupation associated with wind farm construction is also considered. In the decommissioning and end-of-life treatment stage, it is assumed that metallic materials, including steel, iron, aluminum, and copper, are recovered at a rate of 90%. Materials such as resin are treated by incineration, while other materials are disposed of via landfilling.
