ship generator set / diesel / propeller shaft-driven
Options and accessories:
For additional shaft motor operation the diode rectifier is replaced by a PWM rectifier similar to the PWM inverter and the system control is adapted accordingly. With this configuration motor operation is provided as follows:
Booster propulsion operation parallel to the main engine to enlarge the propulsion power and the ship’s speed
Take home respectively take away propulsion operation as emergency propulsion drive without main engine in case of a malfunction of the main engine. For this mode the main engine has to be declutched from the propeller shaft
The “Power Take In” mode is also possible to be fed by the main switchboard, which is supplied by auxiliary generator(s) and independent from a WHRS. Summarized this allows a maximum degree of freedom in power distribution between different units by using only one shaft generator converter.
