heal.abstract	The hydrodynamic performance of a vessel is part of early design stage’s investigation. Economic efficiency of the ship is directly related to its hydrodynamic performance. The present diploma thesis focuses on the optimization of the hydrodynamic performance of DTMB 5415M destroyer with modifications concerning appendages only. The hull was parametrically designed within CAESES environment.Three optimization schemes were carried out in order to investigate how local modifications affect the performance of the vessel both in calm and rough water. Two objectives were selected, namely F1 and F2. Their definition was given within AVT-204 ‘Assess the Ability to Optimize Hull Forms of Sea Vehicles for Best Performance in a Sea Environment’, issued by NATO, and they form a summation of resistance and seakeeping qualities related to the operation profile of the ship. They concern both service and maximum speed attained. A multi-objective and two single objective optimizations were carried out by employing NSGA II algorithm and using the same input values. SWAN2 was used for the prediction of the hydrodynamic performance of the vessel in calm water, while Frank code was selected for the evaluation of seakeeping qualities, both at regular and irregular waves.	en
