Parametric Design of Maintenance Catamaran and Optimization of Resistance Performance

Yunping Xie, Tianmin Gao, Chenlu Jin, Zijian Zhao

Based on the main influence parameters of the 25m twin-body wind power operation ship type, combined with the parametric design concept, the NAPA Basic language macro program was compiled to realize the parametric modeling of the series ship type.The resistance performance prediction of the ship model is carried out by STAR-CCM+ numerical simulation software, the calculation results are imported into Isight optimization software, MIGA is used to optimize the resistance performance , and finally the optimal combination of ship type parameters is obtained. It can provide some reference for the design of catamaran type wind power maintenance ship.
