Numerical Optimization of the Ship Hull from a Hydrodynamic Standpoint

The numerical procedure for an optimization of a ship hull from a hydrodynamic standpoint is presented in the paper. In the procedure, a potential flow solver coupled with the genetic algorithm has been used. As an objective function, the wave resistance has been chosen. The optimization procedure has been applied for the Series 60 (CB=0.60) hull taken as reference hull. Depending on imposed geometrical constraints, several variations of the ship forebody have been obtained. The results from the numerical predictions indicate that the obtained hull forms yield a reduction in wave resistance.
