Propulsion system can experience large power absorption fluctuations during tight manoeuvres. In the case of a turning circle manoeuvre 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 manoeuvring performance. In this work, a series of unmanned free running self-propelled model tests have been carried out in order to investigate the influence of different propulsion system operation settings on the vessel's manoeuvring characteristics.

Abstract
Propulsion system can experience large power absorption fluctuations during tight manoeuvres. In the case of a turning circle manoeuvre 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 manoeuvring performance. In this work, a series of unmanned free running self-propelled model tests have been carried out in order to investigate the influence of different propulsion system operation settings on the vessel's manoeuvring characteristics.| File | Dimensione | Formato | |
