Abstract

In order to improve seakeeping performance of the slender catamaran, Semi Submerged Bow (SSB) anti-pitching techniques is applied. Based on CFD method to forecast the longitudinal motion of the original catamaran (without SSB) in regular waves, and the calculation results and the ship model test results were compared, results show that the numerical method can effectively predict the longitudinal motion of the slender catamaran in regular waves. Semi Submerged Bow is added to the bottom of two demi-hull respectively, and the longitudinal motion in regular waves is predicted. The results show that the longitudinal motion amplitude of catamaran with SSB is smaller than the catamaran without SSB. The installation of SSB reasonably can effectively improve the seakeeping performance of the catamaran.
