Establishment of a design study for comprehensive hydrodynamic optimisation in the preliminary stage of the ship design

An automated practical multi-objective optimisation scheme is proposed for ship hull modification. A shift transformation and a self-blending method are sequentially performed based on resistance objectives at multi-design speeds. The Lackenby variation alters forms produces initial designs. Subsequently, combines obtained ships to cover design space. All processes by MATLAB coding that connects the ©Maxsurf modeller Resistance in case of panel calculation. After whole shape optimisation, platform defines portions stern bow regions. Particularly, an approximation modelling Least-Square approach investigated construct surrogate model. Optimisation results indicate 11.26% cost function reduction contributes 16.23% lower speed 6.12% higher passenger catamaran boat. Thus, developed in-house code provides optimal cost-effective solution hydrodynamic preliminary stage design.
