Contribution to Conference
In order to improve operating economy of a container ship, its hydrodynamic performance is improved by optimizing bow and stern hull-forms with parametric hull form generation method. Different optimization algorithms are deployed to obtain the optimum hull form at the condition of design draft and design speed when displacement is defined as a basic constraint. The paper uses STARCCM+ to calculate the resistance in still water, while added resistance is calculated by STF strip method. By comparing the numerical results, a satisfying hull form can be found. Both powering performance and seakeeping performance are improved.
