Use advice for data set
| When using this LCA data set, attention should be paid to the specific stages of the wind farm's lifecycle: manufacturing of materials and equipment, transportation and installation, operation and maintenance, and dismantling and recycling. Users should apply the data pertinent to these stages accordingly in their assessments. Due to the complexities of offshore wind farm installations, modelers must account for the transportation energy and emissions associated with sea transportation as calculated from the transportation load and the energy intensity of the different specialized vessels involved. Care should be taken to include the correct parameters for the on-grid electricity provision functional unit. Sensitivity analysis should be conducted to understand the impact of data uncertainties on the overall results. |

Technical purpose of product or process
| The Donghai Bridge Offshore Wind Farm (DBOWF) is designed for the generation of on-grid electricity utilizing wind energy. The offshore wind turbines consist of 27 units of 3.6MW and 1 unit of 5MW turbines to collectively produce renewable energy. The technical complexity of transporting heavy and large components for the wind turbines necessitates a specialized fleet comprising anchored vessels, dredger ships, concrete mixing vessels, crane ships, and cable-laying vessels. This offshore wind farm serves as a major step in increasing China's renewable energy footprint and reducing reliance on fossil fuels. |
