| Abstract: |
| Based on the patent information collected from the Derwent Innovation Database, this paper analyzes the annual patent information of offshore wind and other major ocean renewable energies, analyzes the correlation between the number of patents for offshore wind, the pressure of carbon emission reduction and the number of new installed capacity per year, analyzes the development of offshore wind power technology, and summarizes the key technological fields of offshore wind power. On the basis of patent information analysis, the paper constructs the prediction and analysis model of offshore wind technology. The results show that the offshore wind power technology has been developing rapidly, and the overall technology maturity of offshore wind has reached 0.87, which means it has entered the saturation stage from the mature stage. As a new alternative technology, floating offshore wind has also been developed rapidly. At present, the technology maturity of floating offshore wind has reached 0.54, which means it has just entered the mature stage from the technology expansion stage. The research shows that the patent analysis technology and technology maturity prediction can be effectively used to analyze the key technology fields of offshore wind power, and predict its technology maturity. |
