Current simulation methods for pulley-and-weight systems in wave basins test have been proposed as practical alternatives to implementing such systems in physical model testing. This study systematically reviews the implementation process of pulley-and-weight systems-based equivalent current load simulation methods and evaluates their performance by comparing them with physical current generation. A semi-floating wind turbine model is used as a case study to demonstrate the method’s practical application. Current drag coefficients under design draft conditions are obtained and validated through wind tunnel and towing tests. Subsequently, an integrated experimental arrangement is constructed in the wave basin, and comparative tests are conducted under both physical and equivalent current conditions. The dynamic responses, including platform motions, mooring system loads, and nacelle accelerations, are measured and analysed. Results show that the pulley-and-weight method reproduces the dynamic response trends with mean motion deviations almost 10 % and mooring load differences within 7 %, however, discrepancies are observed in extreme value measurements. These findings confirm the method’s applicability for steady current conditions and provide quantitative guidance for selecting equivalent load parameters in FWT basin testing.
