Research and Practice on Marine Environmental Impact Tracking Evaluation Index System of Offshore Wind Power Projects During Construction

Abstract

Based on the analytic hierarchy process, an evaluation index system consisting of 3 first-level indexes and 15 second-level indexes was established. The tracking evaluation of marine environmental impact during construction was carried out in three offshore wind farms in Zhuhai, Yangjiang and Shantou, using the evaluation method based on data analysis, which was the first application in this field. The evaluation content covered the qualitative analysis of the environmental management status of the offshore wind power project during the construction period and the implementation of environmental countermeasures as well as the quantitative evaluation of the ecological environmental impact. The comprehensive evaluation results were obtained, and the existing problems and countermeasures were clarified. At the same time, it was suggested to explore the implementation of the whole process of marine environmental impact assessment system, further reduced the impact of engineering construction on the marine environment, and jointly promoted high-quality economic development and high-level protection of ecological environment.
