![]() Considering the generated ice load, the designed structure can maintain a heading angle relative to ice up to 4°. Simulation results show the effectiveness of the proposed ice generation module and its application to station-keeping performance evaluation. The mooring system was modeled and included to reflect the designed operation scenario. Station-keeping simulation in the time domain was conducted for the same floating structure used in the model test. The developed module is connected to commercial dynamic analysis software (OrcaFlex) as an external force input. Using the results of a captive model test conducted in multiple directions, the statistical characteristics of ice loads were analyzed and processed so that an ice load corresponding to an arbitrary angle of the structure could be generated. The developed module was applied to a time domain simulation. An ice load generation module is proposed based on the experimental data measured at the KRISO ice model basin. ![]() However, present methods for performance evaluation in the time domain are not effective in terms of time and cost. To assess the station-keeping performance of floating structures in the Arctic region, the ice load should be considered along with other environmental loads induced by waves, wind, and currents. ![]()
