Description
Summary:Offshore wind power has gained much attention as a clean and renewable source of energy. In cold regions, offshore wind farms (OWFs) face many challenges due to sea ice cover. In response to these challenges, this paper establishes a scheme to evaluate sea ice parameters for the design of wind power projects. We have successfully applied this scheme to the OWF in the Bohai Sea. The scheme is based on data from sea ice satellite images, operational forecasting systems and field tests. The ice period, joint probability distribution function of ice velocity and thickness, and return period (RP) of thickness are investigated. Moreover, we determine the air temperature relationship between the OWF and Laizhou city. Then, the effective ice temperature is calculated for the OWF based on the air temperature. Combining the RPs of ice temperature and thickness, we compute the RPs of bending and compression strengths, which are two key parameters for the ice load design of wind turbine towers. Our scheme is feasible to implement and can provide complete sea ice information for OWFs from the stages of design and construction to operation. •A feasible scheme is proposed to appraise sea ice parameters for the design of offshore wind farms in the cold regions.•The PDF of sea ice thickness and velocity obey the log-normal and exponential distributions, respectively.•The independence of the velocity on the thickness of sea ice are thoroughly inspected to obtain their joint PDF.•Sea ice strengths of recurrence periods are calculated by combining the thickness and the effective ice temperature.
