MAN B&W Auxiliary Propulsion System. Remote control system
The el-motor/alternator and clutch control system is integrated with the CP Propeller and main engine system.
The automatic PTI start-up sequence includes, eg interlocks for ‘main engine stopped’, ‘Clutcher in clutched-out position’, ‘el-motor/alternator clutched out’, gearing in the tunnel gear ‘changed to the PTI step-down ratio’, ‘propeller pitch adjusted to zero-position’. And then follows the transformer-start of the el-motor and the clutching in at the tunnel gear. In auxiliary propulsion mode the power absorption of the CP Propeller is controlled to stay within the load range of the el-motor. All electrical circuits of the control system are monitored by the alarm system.
