ObjectivesThis study analyzes the influence of interceptors on the resistance and motion characteristics of ships in regular waves.MethodsTaking a semi-displacement ship as the research object, the numerical simulation of its resistance and motion characteristics with and without interceptors in regular waves is carried out based on the RANS method and overset mesh. The variation laws of ship resistance, attitude and motion response with wavelength and ship speed are summarized.ResultsThe results show that the resistance reduction effect of interceptors in regular waves is about 1.03%–2.43% higher than that in calm water. The influence of interceptors on the heave and pitch transfer functions increases with the increase in wavelength. The average reduction rates of heave transfer function TF3 and pitch transfer function TF5 under λ = 2LPP conditions are 3.5% and 1.4%. When the phenomenon of green water on deck occurs, the interceptors can reduce TF3 and TF5 by 9% and 3%.ConclusionsThe results of this study can provide valuable technical references for the design and performance prediction of ship energy-saving devices.
