Abstract
Propulsion system can experience large power absorption fluctuations during tight maneuvers. In the case of a turning circle maneuver for a twin-screw ship, the power required by the two shaft lines can be completely different; in case of non conventional propulsion system, like cross-connect configurations, a compromise must be met in order to design a safe control system without affecting dramatically the vessel's maneuvering performance. In this work, a massive experimental activity via free running model tests have been carried out in order to investigate the influence of different propulsion system operation settings on the vessel's maneuvering characteristics.| File | Dimensione | Formato | |
