Motion response analysis for a Resonance-Free SWATH

Abstract

SummaryThe paper describes the computational method for motion responses on a Resonance-Free SWATH (RFS), which has extremely small water-plane area and it leads to the feature close to the resonance-free in the motion responses. Theoretical calculations based on the strip theory are carried out and compared with experimental results in regular head waves. The influence of forward speed on lift due to hydrofoils and lower hulls are large and numerically modeled well. Hydrodynamic interaction between twin hulls is well computed through the introduction of a practical manner.
