The current study investigated the variability of the main parameters of drifting level ice during ice season and how this variability affects the ice load. The study was carried out on the example of hydraulic protective structures of the floating nuclear thermal power plant in the city of Pevek. Numerical modeling was performed to determine the ice load reduction factor for the case when the vertical wall is formed by the consolidated ice fragments on an inclined structure. Statistical information on the main ice parameters was gathered and provided in the article. Ice loading calculations were conducted by several calculation methods. Based on the results of the study, general conclusions were made on the specifics of ice loading alternation during ice season and conclusions regarding design ice loading on hydraulic structures in the port of Pevek.
