Résumé
The X-bow concept was developed by Ulstein company, in order to increase the ship hydrodynamic performance. Low resistance, reduced fuel consumption, smoother motion and low acceleration levels are some of the hydrodynamics improvements. A theoretical analysis on the seakeeping performance of a supply vessel with X-bow form was performed by using Aveva Marine Engineering Software and it is presented in this paper. The ship motions and accelerations on irregular waves were calculated and the influence of the roll gyradius and bilge keel was analysed. The conclusion reveals the important influence of the mentioned elements on the ship motions and accelerations.
