Research on Risk Assessment Techniques of Offshore Wind Power Projects during Operation Period

In light of the complex operating environment and high maintenance cost of offshore wind power projects, a risk evaluation system is established in accordance with the risk’s features and sources during the operation period of offshore wind power projects. On grounds of the risk evaluation system, a risk assessment method for offshore wind power projects during the operation period is put forward based on the multi-level fuzzy comprehensive evaluation method, and a specific project in the South China Sea is evaluated with the assessment model. The results showed that the risk probability is moderate to low, the consequences of the hazards are moderate, and the comprehensive risk rating is moderate for the assessed project during the operation period. It is necessary to follow the ALARP (As Low As Reasonably Practicable) principle to mitigate the risk. The risk level of offshore wind farms during the operation period can be judged using the evaluation method to provide technical support for prevention and emergency response of the accidents related to the offshore wind power projects.
